One can always dig their own IP address

  dig TXT -4 +short o-o.myaddr.l.google.com @ns1.google.com

That's neat! I can also find my upstream DNS servers recursive resolver IP by leaving the @ns.google.com off. Looks like my upstream resolvers are using IPv6 :)

Also, I can find the resolver IP for popular public resolvers this way too.

This is probably the coolest thing I will learn about today.
