Recently, I saw icanhazip.com pop up in my pFsense firewall logs. It was immediately blocked but the name piqued my interest, so I did a little digging which revealed an interesting backstory.
It’s owned by Cloudflare:

…but it hasn’t always been theirs: icanhazip: How a simple IP address tool survived a deluge of users. Pretty interesting, at least to me as I have never encountered it before.
I have it still blocked as nothing I’m doing seems hampered by blocking icanhazip.com’s ip range. Anyone else ever encounter icanhazip.com?
I actually worked with Major back when he initially created icanhazip.com. It’s still my go-to for resolving my public IP for scripts that need it. (IE. hand rolled DNS for my home lab k8s cluster).
Wow! It certainly a small world after all.
