What Is My IPv6 Address?
Verify native IPv6 connectivity. Queries an IPv6-only public endpoint to reveal your global unicast address without falling back to IPv4.
Best solution
Network diagnostic: What Is My IPv6 Address?; IPv6 Routing & Query Duration.
Start a lookup to see the address visible to ipify.
A VPN, proxy or relay can change the observed address. HTTPS request time is not ICMP ping, packet loss or internet speed.
Clicking Check contacts ipify, which sees the request address. Results stay in this page. No automatic polling.
Keep fast calculators and daily tools pinned right to your desktop.
Methodology & calculation rule
Connects directly to https://api64.ipify.org over an IPv6 transport socket, returning the external IPv6 exit address.
Network observations execute bounded requests to public measurement backends (ipify, Google Public DNS, Globalping, or Cloudflare). Measurements distinguish local client configuration from external internet reachability.
No browsing history, private tokens, or credentials are captured. Results are snapshots of external probe vantage points at the recorded observation timestamp.
Real-World Context & Technical Standards
128-Bit Hexadecimal Addressing
IPv6 uses 128-bit addresses (yielding $3.4 \times 10^{38}$ unique addresses) represented as eight 16-bit hexadecimal blocks separated by colons, with '::' compressing consecutive zero blocks.
Temporary Privacy Extensions
Modern operating systems (macOS, iOS, Windows, Android) periodically randomize the lower 64 bits of their public IPv6 address to prevent third-party website tracking across browsing sessions.
Elimination of NAT Workarounds
Because IPv6 supplies abundant globally unique addresses, consumer devices communicate without Network Address Translation (NAT), simplifying peer-to-peer protocols and SIP communications.

Frequently Asked Questions
Why does my connection report an IPv4 address but no IPv6 address?
Many residential ISPs and older home routers still lack native IPv6 support or have IPv6 disabled in WAN configuration, operating exclusively on legacy IPv4.
What is an IPv6 temporary privacy address (RFC 4941)?
Modern operating systems generate randomized, temporary interface identifiers for outgoing IPv6 traffic that rotate periodically to prevent advertisers from tracking your hardware across networks.
