Hmm, the RDAP-ification of the domain world is kinda crap, the default "whois" command that ships on ubuntu (and friends) doesnt do RDAP, and it seems that some ccTLD's have shut down their whois "port 43" servers without actually doing RDAP, one example being .co (Columbia)

[15:17:34] ben@ossa:~$ whois example.co
getaddrinfo(whois.nic.co): Name or service not known

I guess this basically gives you casual domain privacy for all .co domains???

@benjojo Your whois client is outdated (finding the server is an issue that RDAP solves nicely…)

The real whois server, as mentioned in the reference database (at IANA) is whois.registry.co, which works.

@bortzmeyer Right but .co does not seem to have RDAP, my whois client is whatever ships with Ubuntu 24.04

[15:22:26] ben@ossa:~$ whois --version
Version 5.5.22.

Report bugs to <md+whois@linux.it>.

@benjojo whois has no standard way of finding the right server. Clients rely on various heuristics.

If you don't want Ubuntu to upgrade whois, add "\.co$ whois.registry.co" in /etc/whois.conf.

Or ask .co to enable RDAP.

@bortzmeyer

alas, my soft power in the BGP world does not translate over to the DNS one :)

@benjojo Fixed two days ago: https://salsa.debian.org/md/whois/-/commit/71c87b5e30fdb57109bae753f31a3b41928908f3 .

Maybe somebody who cares about Ubuntu can make backports.

I have still not decided if it is a good idea to implement RDAP here since I am not eager to do JSON processing in C.

@rfc1036 @benjojo And the RDAP scheme is fucked

@alarig @rfc1036 oh my god yes, Insane format, bgp.tools's parser is unending misery that rapidly just descends into "vibe parsing" in the random hope it hits the right thing.

I have no idea who they designed the RDAP format for, but makes zero sense if you have a actual parser that needs static structures to unpack something into
