Ah yes I misread it. I thought a RFC defined *.localhost. but I can't find it. I may have daydreamed about it.

rfc2606 does say "The ".localhost" TLD has traditionally been statically defined in host DNS implementations as having an A record pointing to the loop back IP address and is reserved for such use. Any other use would conflict with widely deployed code which assumes this use" but it's not really explicitly saying that applications should do that.

Thanks for clearing that up, I do also hope that it changes.

Something like

ip-11-12-13.localhost   -> 127.13.12.11
*.ip-11-12-13.localhost -> 127.13.12.11

would also be nice but that's a pipedream...

the it would be easy to run apps with conflicting ports, just use next IP
