This is a service provided by some DNS hosts, with their own special subdomains, and is not universal. They may also require slightly different options.

Other options include:

• Google (query for txt record): @ns1.google.com o-o.myaddr.l.google.com

• Akaimai (query for txt record): @ns1-1.akamaitech.net whoami.akamai.net

• Cloudflare: @1.1.1.1 whoami.cloudflare

• Cisco (there are four, as far as can tell): @resolver[1-4].opendns.com myip.opendns.com

…and likely others.

exept it does? At least in ipv6 land

IP chicken is another option

For us Linux users (BTW), this wtfismyip script just dumps a text string. Just save it to /usr/local/bin or some other location in your path and make it executable, and install the lynx text www browser if you don't have it installed already.

There are a lot of ways to do this, but this works and I'm lazy...

root@tux:~# cat $(which wtfismyip)
#!/bin/bash

printf "%s\n" "Your fucking IP address is $(lynx -dump -nolist http://wtfismyip.com/text)."

root@tux:~# wtfismyip
Your fucking IP address is 13.107.226.41.

I use thiscomputer.info

It's just text. It shows a bit more than just your IP. And it's easy to remember.

i could see a situation where a host that only speaks IPv4 would need to add my IP to an allow list, and therefore I would need to check what IPv4 address I appear as, even though I am running IPv6.

Glad somebody else posted it. Glad it still exists. Some of the internet is still hilarious and amazing.

ip.me also works well in the terminal with curl. The default response is plaintext
