It seems like xip.io stopped existing without any announcements at least to me. The URL responds with ERR_NAME_NOT_RESOLVED.<p>Was there any announcements, and what would be good alternatives?
No announcement that I'm aware of, but I've used <a href="https://nip.io" rel="nofollow">https://nip.io</a> in a pinch before and haven't encountered any issues. Like xip.io, it supports IPv4 only and uses PowerDNS.
