I found this quite amusing as it seems as if Google is trying to impersonate Cloudflare's 1.1.1.1, whereas 010.010.010.010 is indeed the octal representation of 8.8.8.8. Credit: IPv4 addresses are silly, inet_aton(3) doubly so. https://www.netmeister.org/blog/inet_aton.html

For me the link on HN is to https://dns.google/ but I'm pretty sure it's supposed to be to https://010.010.010.010/ (which redirects, for me). Did the admins change it?

Earlier quoted context omitted.

I was just about to edit my comment: either that is the case or HN automatically runs a reverse DNS query to get the domain name associated with the IP address in the submission URL?

More likely they do an HTTP request and if there's a redirect they update the link.
