What Is My IPv6 Address?
IPv6 is the newer version of the internet protocol. Addresses are 128 bits long and written in hexadecimal with colons (e.g. 2001:0db8:85a3::8a2e:0370:7334). They were introduced because the supply of IPv4 addresses is limited. Many ISPs and networks now offer IPv6 alongside IPv4 (dual-stack), so your device may have both. This page shows the public IPv6 address that websites see when your connection has IPv6.
If you don’t see an IPv6 here, your ISP or router might not be providing it yet. You can still use the internet with IPv4. To see your IPv4 or both, use What is my IP. For location and network details, use our IP lookup or IP location finder.
How to Use This Tool
Open this page and your public IPv6 (if available) is shown automatically. No form to submit. For IPv4 only, try My IPv4 address. For reverse hostname of an IP, use reverse DNS lookup; for domain records, use DNS lookup.
Features
- Shows your public IPv6 when your network supports it
- Clear message when IPv6 is not available
- No signup; we don’t store your IP
- Works on any device
Why Use This Tool
Some services or firewall rules are tied to IPv6. Developers and admins use it to confirm their server or connection is using IPv6. Pair it with a ping test or traceroute tool for diagnostics. Our DNS lookup shows AAAA records (IPv6) for domains.
FAQs
What is my IPv6 address?
Your IPv6 address is the 128-bit identifier for your device on the internet, written in hexadecimal (e.g. 2001:db8::1). This page shows the public IPv6 that sites see if your network supports it.
Why don't I see an IPv6 address?
Your ISP or router may not have IPv6 enabled. Many home connections still use IPv4 only. You can still see your IPv4 on our What is my IP or My IPv4 Address page.
Is IPv6 replacing IPv4?
They run side by side (dual-stack). IPv6 is used where available; IPv4 is still common. Over time more of the internet is moving to IPv6.
Can I have both IPv4 and IPv6?
Yes. Many networks assign both. Your device will use whichever is appropriate for the destination. Our What is my IP page shows both.
Is checking my IPv6 free?
Yes. The tool is free and we do not store your IP.
