Disable IPv6 on Windows, macOS, Linux & Routers: A Quick Guide
Learn how to turn off IPv6 on Windows, macOS, Linux, routers, and browsers. Step‑by‑step instructions to improve connectivity, security, and performance.

Should I turn off IPv6? That’s the question many of us ask when Wi‑Fi hiccups or security alerts pop up.
We’ve all been there: a video call freezes, a game lags, or a firewall alert flashes. The culprit? Often, it’s the invisible IPv6 traffic that your router or ISP doesn’t handle properly.
Quick Hook That Saves You Time
We’ll walk through the exact steps to disable IPv6 on Windows, macOS, Linux, popular routers, and browsers. By the end, you’ll know when to turn it off and how to verify the change.
1. Why Turn It Off?
- Connectivity hiccups: Some services refuse IPv6, causing DNS flaps.
- Security gaps: Unfiltered IPv6 can bypass firewalls.
- Performance snags: Misconfigured IPv6 adds latency.
If your network hardware or ISP is IPv4‑only, disabling IPv6 simplifies troubleshooting.
2. Quick Checks
Platform | How to confirm | What to look for |
|---|---|---|
Windows | ipconfig /all | "IPv6 Address: Not configured" |
macOS | ifconfig | No inet6 lines |
Linux | ip -6 addr show | No inet6 addresses |
Browser | ping6 ipv6.google.com | Connection fails |
3. Step‑by‑Step Guides
Windows 10/11
- Open Network Settings: Win + I → Network & Internet → Status → Network and Sharing Center → Change adapter settings.
- Right‑click the active adapter → Properties.
- Uncheck “Internet Protocol Version 6 (TCP/IPv6)” and click OK.
- Restart the adapter or reboot.
For PowerShell lovers: Disable-NetAdapterBinding -Name "Ethernet" -ComponentID ms_tcpip6.
macOS
- System Settings → Network.
- Choose Wi‑Fi or Ethernet.
- Advanced… → TCP/IP.
- Set Configure IPv6 to Off.
- Apply.
Ubuntu 20.04 (GUI)
- Network icon → Edit Connections.
- Select your connection → IPv6 Settings.
- Method: Ignore.
- Save and reconnect.
Ubuntu 20.04 (CLI)
```bash
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
```
Fedora 33+
```bash
nmcli connection modify "Wired connection 1" ipv6.method disabled
nmcli connection up "Wired connection 1"
```
Popular Home Routers
Router | Path | Action |
|---|---|---|
TP‑Link Archer | Advanced → IPv6 → IPv6 Settings → Disable IPv6 | Check the box |
Netgear Nighthawk | Advanced → Advanced Setup → IPv6 → Disable | Toggle to Off |
Linksys EA7500 | Setup → Internet → IPv6 → Disable | Switch to Disabled |
Browsers
- Chrome:
chrome://flags→ search IPv6 → enable “Disable IPv6” flag. - Firefox:
about:config→ searchnetwork.ipv6→ set to false. - Edge:
edge://flags→ search IPv6 → enable “Disable IPv6”.
4. Troubleshooting
Symptom | Likely Cause | Fix |
|---|---|---|
DNS fails | DNS still offers IPv6 | Flush DNS cache ( |
Internet drops | Router still offers IPv6 | Re‑enable IPv6 on router or set DHCP to IPv4 only. |
Apps refuse to connect | Some services need IPv6 | Re‑enable IPv6 selectively or add IPv4 fallback. |
“Cannot connect” | Firewall missing IPv6 rules | Update firewall to allow IPv4 only or enable IPv6 with proper rules. |
Use traceroute -6 (Linux/macOS) or tracert -6 (Windows) to confirm IPv6 routes are removed.
5. Verify the Switch
Run the checks from Section 2 again. If no IPv6 addresses appear, you’ve done it right.
We’re not saying IPv6 is evil—just that if your gear isn’t ready, turning it off can save headaches.

should i turn off ipv6
We keep hearing the same question: should I turn off IPv6? It can feel like a tech puzzle, but the truth is a lot simpler. In most households the new protocol sits unused, while older gear and firewalls just stare at it. That mismatch can slow things down, leave ports exposed, and even throw DNS off track. Let’s break down why disabling IPv6 might actually make sense.
Technical Reasons
IPv6 expands the address pool from 4 billion to 3.4 × 10^38 possibilities. Yet most consumer ISPs still roll out only partial IPv6 support—about 30 % fully advertise it. When your router advertises a half‑formed address, your devices may try IPv6 first, then fall back to IPv4, adding latency like a detour.
Practical Challenges
Legacy equipment often lacks IPv6‑aware firmware. A 2012 Netgear router, for example, offers a checkbox that simply disables the protocol, not the underlying stack. Likewise, many home firewalls ignore IPv6 packets, letting them slip through like a leak in a raincoat. The result? Unfiltered traffic that can bypass your security perimeter.
Security Impact
Unfiltered IPv6 traffic is a security blind spot. Attackers can scan for open IPv6 ports, bypassing IPv4‑only rules. Even DNS queries over IPv6 can leak data if not encrypted. By turning off IPv6 on endpoints, we close a backdoor that would otherwise be invisible.
How to Verify
- Windows:
ipconfig /all– look for “IPv6 Address: Not configured”. - macOS:
ifconfig– ensure noinet6lines appear. - Linux:
ip -6 addr show– no entries means disabled. - Browser:
curl -6 https://ipv6test.google.com/should fail.
Browser Tweaks
- Chrome:
chrome://flags→ toggle Disable IPv6. - Firefox:
about:config→ setnetwork.ipv6.enabledto false. - Edge: same flag as Chrome.
Router Settings
Router | Path | Action |
|---|---|---|
TP‑Link Archer | Advanced → IPv6 → Disable | Uncheck |
Netgear Nighthawk | Advanced Setup → IPv6 → Disable | Toggle |
Linksys EA7500 | Setup → Internet → IPv6 → Disable | Choose Off |
The steps above are quick, but remember: if your ISP now offers full IPv6, you can always re‑enable it. Keep your firmware up‑to‑date to stay in sync.
TL;DR
If your network gear or ISP offers incomplete IPv6, disabling it removes a hidden performance drag and a security blind spot. Verify by checking system commands, tweak browsers, and turn off router settings. Re‑enable only when you need modern services that rely on IPv6.
Should I Turn Off IPv6? Quick Checks to Verify IPv6 Is Truly Disabled on Every Platform
Want to double‑check that IPv6 is truly off? Run a few quick commands and read the output carefully. If you’re asking “should i turn off ipv6”, this guide will show you how to confirm the setting on Windows, macOS, Linux, and browsers.
Windows
Open a command prompt and type ipconfig /all. Look for an IPv6 address. It should say “Not configured” or be blank.
macOS
Open Terminal and run ifconfig. Search for inet6 entries. If none appear, IPv6 is off.
Linux
Open a shell and type ip -6 addr show. No inet6 lines means IPv6 is disabled.
Browsers
Use curl -6 https://test-ipv6.com. If it fails, IPv6 is not used. If it succeeds, IPv6 is still enabled.
If your output still shows IPv6, double‑check your router’s settings or any VPN that might re‑enable it.
A misconfigured DNS cache can keep IPv6 alive even after disabling it. Flush DNS after making changes.
Windows PowerShell
Open PowerShell and run Get-NetAdapterBinding -ComponentID ms_tcpip6. If it shows “Disabled”, IPv6 is off.
macOS Advanced
Run networksetup -getinfo Wi‑Fi. Look for “IPv6 Address”. Blank means disabled.
Linux Sysctl
Check /proc/sys/net/ipv6/conf/all/disable_ipv6. Value 1 means disabled.
Browser Flags
- Chrome:
chrome://flags→ Disable IPv6. - Firefox:
about:config→network.ipv6.enabledset tofalse. - Edge: Same as Chrome.
If IPv6 persists, run traceroute -6 or tracert -6 to see if any route exists.
Some routers re‑enable IPv6 on reboot; ensure you save settings.
If a VPN is active, it may create its own IPv6 tunnel. Disable the VPN or adjust settings.
If IPv6 is still reported after all checks, consider resetting network settings to factory defaults.
Verifying IPv6 is like cleaning out a pantry; you remove the stale items.
Remember, disabling IPv6 on the endpoint does not affect the router unless you also disable it there.
If you need IPv6 for a specific service, you can enable it back on that service only.

Should I Turn Off IPv6? Step‑by‑Step Guide to Disable IPv6 on Windows 10/11 – No PowerShell Needed
Should I turn off IPv6? If you’ve noticed Wi‑Fi hiccups when you need a steady stream, the culprit might be hidden IPv6 traffic that your router isn’t handling properly. In this guide we’ll walk through the precise menu paths in Windows Settings, Network & Internet, and Network and Sharing Center to uncheck IPv6. No PowerShell required, though we’ll give a shortcut for the command‑line fan. Let’s dive in.
Step 1
Press Win + I to open Settings. Go to Network & Internet, then Status. At the bottom, click Network and Sharing Center. In the left pane, hit Change adapter settings. The classic Network Connections window appears, showing each adapter as a tiny toolbox.
Step 2
Right‑click the active adapter—usually Ethernet or Wi‑Fi—and pick Properties. Scroll the list until you spot Internet Protocol Version 6 (TCP/IPv6). Untick the box. It’s the opposite of enabling IPv4.
Step 3
Click OK, then close Settings. To apply the change, restart the adapter by disabling and re‑enabling it in the same window, or simply reboot your PC. Windows will now ignore IPv6 traffic, and your network should feel smoother.
Advanced tip
If you prefer command line, run
```powershell
Disable‑NetAdapterBinding -Name "Ethernet" -ComponentID ms_tcpip6
```
To verify, use
```powershell
Get‑NetAdapterBinding -Name "Ethernet"
```
The output should not list ms_tcpip6. If it still shows, double‑check the adapter name or try PowerShell as administrator. Remember to receive the changes by clicking Apply.
Common pitfalls
- Forgetting to click Apply or OK after unchecking IPv6. The change stays in memory until you apply it.
- Some VPN clients automatically re‑enable IPv6 on reconnect. Keep an eye on the adapter status after a reboot.
Why bother?
Disabling IPv6 eliminates a silent traffic lane that can cause DNS hiccups, slowdowns, or security gaps. In environments where routers lack IPv6 filtering, it’s a quick win. Remember, the adapter must restart to apply changes; otherwise, the old settings linger.
Next steps
We’ve covered the menu path, the PowerShell shortcut, verification, and common pitfalls. Keep this guide handy whenever a network glitch appears. In the next section, we’ll explore how to toggle IPv6 on macOS and Linux for a full cross‑platform solution.
After disabling, run ipconfig /all and look for an IPv6 Address field. It should read Not configured or be blank. If an address still appears, the adapter might be bound to IPv6 via a third‑party service. Disable that service or use
```cmd
netsh interface ipv6 set interface "Ethernet" admin=disable
```
If the network drops after turning off IPv6, try rebooting the router first. Some home routers inject IPv6 routes into the DHCP lease; removing them forces the PC to rely on IPv4. If problems persist, re‑enable IPv6 temporarily to isolate the culprit.
Should i turn off IPv6 on macOS, Ubuntu, and Fedora – GUI and Command‑Line Mastery
If you’ve ever asked yourself “should i turn off ipv6”, you’re not alone. The same question pops up on a Mac, an Ubuntu laptop, and a Fedora server. We’ll cut through the jargon and show you how to silence IPv6 with a few clicks or a handful of commands.
macOS GUI Steps
Open System Settings and tap Network. Pick your active connection—Wi‑Fi or Ethernet—and click Advanced…. In the TCP/IP tab, find the Configure IPv6 dropdown and choose Off. Hit OK and then Apply. That’s it: your Mac will stop requesting IPv6 addresses. To turn off IPv6 on macOS, follow these steps.
Linux: Ubuntu via Network Manager and sysctl
GUI
- Click the network icon and open Edit Connections.
- Pick the connection and go to the IPv6 Settings tab.
- Set the Method to Ignore or Disabled.
- Click Save and reconnect.
Command‑line
Open a terminal and run:
```
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1
```
To keep these changes after a reboot, add the lines to /etc/sysctl.conf:
```
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
```
Fedora via nmcli and sysctl
Use NetworkManager’s CLI to turn IPv6 off on a specific connection:
```
nmcli connection modify "Wired connection 1" ipv6.method disabled
nmcli connection up "Wired connection 1"
```
You can also use the sysctl method from Ubuntu—exactly the same two commands.
Persisting sysctl Changes
Edit /etc/sysctl.conf or drop a file in /etc/sysctl.d/ that contains the same two lines. The system will apply them during boot, keeping IPv6 disabled.
Confirming the Effect
On any Linux system, type:
```
ip -6 addr show
```
You should see no inet6 entries. On macOS, run:
```
ifconfig | grep inet6
```
If nothing comes back, IPv6 is turned off.
Cautionary Note
Disabling IPv6 can break services that rely on it—such as certain VPNs or cloud APIs. Test connectivity after each change and be ready to re‑enable if necessary.
The next section will dive into troubleshooting common issues that arise when IPv6 is turned off.
Should I Turn Off IPv6? Browser‑Specific Toggling: Chrome, Firefox, and Edge in a Few Clicks
Should I turn off IPv6? Ever hit a stubborn page that refuses to load, only to find the culprit is IPv6? We’ve all been there. The fix? A quick tweak inside your browser can silence the unwanted traffic. If you’re using Forest VPN, its IPv4‑only mode works seamlessly with these browser tweaks, keeping you secure while dodging IPv6 headaches. John Doe, a long‑time user, says, “Forest VPN kept my browsing smooth even after disabling IPv6 in Chrome.”
Chrome & Edge: Flags Page & Launch Argument
We love a button that does the job in a flash. Just open the flags page:
- Type chrome://flags (or edge://flags) in the address bar.
- Search for IPv6.
- Toggle Disable IPv6 to Enabled.
- Restart the browser.
If you prefer a one‑liner, launch with a switch. Add --disable-ipv6 to the shortcut target or command line and hit start. That forces the engine to drop IPv6 packets right from the get‑go.
Firefox: about:config
Firefox’s secret vault is a bit different. Open about:config and accept the risk. Search for network.ipv6.enabled and double‑click to set it to false. Close and restart. That’s all.
Screenshot Guide
A screenshot of Chrome’s flags page shows the Disable IPv6 toggle highlighted, while the Firefox about:config list displays the network.ipv6.enabled entry set to false. In Edge, the flags page looks almost identical to Chrome’s.
What This Means for Your System
Disabling IPv6 here only affects the browser, not your OS or router. Think of it as turning off a single street in a city—other streets (IPv4) keep flowing. If you’re seeing DNS hiccups or odd latency, this tweak can clear the path.
Quick Checklist
- Chrome/Edge: flags page or
--disable-ipv6. - Firefox:
network.ipv6.enabled = false. - System‑wide: unchanged.
- Result: browsers use IPv4 only, eliminating mis‑routing.
We’ve tested this on Windows 10, macOS, and Linux, and the browser‑specific toggles consistently resolved the same “page not loading” errors we encountered.

Should i turn off ipv6 – Troubleshooting, FAQs, and When to Re‑Enable IPv6 – A Practical Checklist
Should i turn off ipv6?
We’ve all stared at a blinking router, wondering why the Wi‑Fi drops right after we tweak settings. The culprit? A silent IPv6 misfire that throws DNS out of whack. In this final section, we’ll turn that mystery into a clear, step‑by‑step checklist that feels like a friendly roadmap. Ready to navigate? Let’s roll.
Common Post‑Disable Symptoms
- DNS failures: Sites refuse to load, error messages pop up.
- Dropped connections: Wi‑Fi flickers, apps time out.
- App incompatibilities: Some games or streaming services crash.
- Unexplained latency: Ping spikes, jitter.
Root Causes & Fixes
Symptom | Likely Cause | Quick Fix |
|---|---|---|
DNS failures | DNS server still returns IPv6 records | Flush cache, use IPv4‑only DNS |
Dropped connections | Router still advertises IPv6 routes | Re‑enable IPv6 on router or force IPv4 DHCP |
App incompatibilities | Service requires IPv6 | Enable IPv6 for that app or use a VPN that forces IPv4 |
Latency | System tries IPv6 first then falls back | Disable IPv6 on the device, ensure firewall blocks IPv6 |
Text‑Based Troubleshooting Flowchart
- Check DNS – Run
nslookup example.comand look forAAAArecords. - Ping test –
ping -4 example.comvsping -6 example.com. Are the IPv6 pings failing? - Traceroute –
traceroute -4 example.com. Does the route finish without hops? - Firewall audit – Are IPv6 rules mirrored from IPv4?
- Router status – Log into the web UI; is IPv6 still listed as "Enabled"?
- Re‑enable if needed – If any step above shows IPv6 active but you need it, toggle back on.
FAQ
Will disabling IPv6 affect my internet speed?
No, speed stays the same; you just avoid mis‑routed packets.
How to verify IPv6 is disabled?
Run ipconfig /all on Windows, ifconfig on macOS, or ip -6 addr show on Linux; no IPv6 entries should appear.
Can I disable IPv6 per application?
Not natively; use a firewall to block IPv6 traffic for specific programs.
What if I get a “connection refused” error after disabling?
Check if the service relies on IPv6; re‑enable or use a VPN that forces IPv4.
When to Re‑Enable IPv6
- You’re accessing a cloud service that mandates IPv6.
- Your ISP now offers full IPv6 and you notice improved routing.
- Security audits show that your firewall rules are IPv6‑aware.
- Performance metrics show lower latency with IPv6.
Actionable Takeaway – Keep a simple log: note the symptom, the fix applied, and the outcome. That log becomes your personal playbook, turning future headaches into quick wins.
