Ways of finding your IP

I was chatting with a friend who is doing his AZ-700 and he had found this rather neat way of finding your IP using Google DNS.

dig TXT o-o.myaddr.l.google.com @ns1.google.com +short

This led us down a rabbit hole to find other similar ways of doing it with DNS.

Cloudflare

dig @1.1.1.1 ch txt whoami.Cloudflare +short

OpenDNS

dig +short myip.opendns.com @resolver1.opendns.com

Akamai

dig whoami.akamai.net. @ns1-1.akamaitech.net. +short
