IPv4 / IPv6

You reached this page over IPv4. This host is dual-stack: your client picked the family, and the server can only ever see the address it was reached from.

/ipv4your IPv4 address, or an error if you connected over IPv6
/ipv6your IPv6 address, or an error if you connected over IPv4
curl -4 www.ipecho.meforce curl to connect over IPv4
curl -6 www.ipecho.meforce curl to connect over IPv6

To see your IPv6 address from a browser you need a hostname that only resolves over IPv6. From the command line, curl -6 www.ipecho.me does the same thing.

Endpoints

curl/wget get plain text, browsers get HTML. Append .txt, .json or .html to force a format.
