What Is My IPv6
Your IPv6 address
Detecting…
Details
- All IPv6 found
- None detected
- Status
- Your connection may be IPv4-only, or IPv6 is hidden by the browser or VPN
IPv6 is gathered via WebRTC ICE candidates and your HTTP connection when available.
How to use
- Open the page — IPv6 addresses are gathered automatically from WebRTC and your connection.
- If no address appears, your network or browser may be IPv4-only — that is normal on many connections.
- Click Copy to save the primary IPv6 address for firewall rules or support tickets.
FAQ
What is my IPv6 address?
Your IPv6 address is the 128-bit identifier your connection may use alongside or instead of IPv4. If detected, it appears at the top of this page in hexadecimal form with colons, for example 2001:db8:85a3::8a2e:370:7334.
Why is no IPv6 shown?
Many ISPs, routers, and VPNs still operate IPv4-only. Some browsers also limit IPv6 exposure in WebRTC for privacy. An empty result usually means IPv6 is not active on your path to the internet.
Is IPv6 the same as IPv4?
No. IPv4 uses 32-bit dotted decimal addresses (for example 203.0.113.42). IPv6 uses 128-bit hexadecimal addresses with colons. A device can have both at the same time — this page shows IPv6 specifically.
Can a VPN hide IPv6?
Some VPNs tunnel IPv4 only, leaving IPv6 exposed outside the VPN tunnel. If you use a VPN and see an IPv6 address here, run a WebRTC leak test to confirm it is covered.
How is IPv6 detected on this page?
The page collects IPv6 addresses from WebRTC ICE candidates and from your HTTP connection when the server sees an IPv6 client. Multiple addresses may appear if you have several network interfaces.
Do I need IPv6?
Most websites still work fine on IPv4. IPv6 matters for networks that have exhausted IPv4 space, for some gaming and P2P setups, and for future-proofing dual-stack infrastructure.
Introduction
What Is My IPv6 shows the IPv6 address(es) your browser and connection expose right now, front and center, with a one-click copy button. Below it, a details panel lists every IPv6 candidate found and explains whether your path to the internet is dual-stack or IPv4-only.
IPv6 adoption is growing, but many home and office networks still run IPv4 only. When IPv6 is active, it can appear in WebRTC probes and HTTP connections independently of your IPv4 address — which matters for VPN leak checks and firewall rules. This page surfaces that address without requiring command-line tools.
What is IPv6?
IPv6 (Internet Protocol version 6) is the successor to IPv4, using 128-bit addresses written as eight groups of hexadecimal digits separated by colons. A shortened form collapses consecutive zero groups:
Full: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
Short: 2001:db8:85a3::8a2e:370:7334
| Version | Length | Example | Status |
|---|---|---|---|
| IPv4 | 32 bits | 203.0.113.42 |
Still dominant on most home networks |
| IPv6 | 128 bits | 2001:db8::1 |
Growing; required on some mobile and enterprise networks |
This tool detects IPv6 only — for your primary public address regardless of version, see what is my IP.
Common use cases
- Dual-stack verification — confirm your ISP or router actually provides IPv6, not just IPv4.
- VPN leak audit — check whether IPv6 is exposed outside your VPN tunnel.
- Firewall configuration — copy your IPv6 for AAAA record whitelisting or server access rules.
- Network debugging — compare IPv6 candidates across browsers or after changing router settings.
Best practices
- An empty result is normal on IPv4-only networks — it does not mean anything is broken.
- If you use a VPN, verify it blocks or tunnels IPv6; an exposed IPv6 can bypass an IPv4-only VPN.
- IPv6 addresses can be temporary (privacy extensions) and rotate — copy the current value rather than assuming it is permanent.
- For a full leak audit including IPv4 and local addresses, run the WebRTC leak test; for your public IPv4, see what is my public IP.
