Recommendations for RDAP client in Bookworm?

[Jeffrey Walton <noloader@gmail.com>]

Hi Everyone,

It looks like Bookworm does not provide a RDAP client.  Searching for
rdap and openrdap in Debians packages does not provide meaningful
results:

    $ apt-cache search rdap
    ruby-discordrb-webhooks - webhook client for discordrb
    libxrdapputils2 - Utilities library for xrootd applications

I see Trixie does offer a RDAP package, however.  Cf.,
<https://packages.debian.org/search?suite=default&section=all&arch=any&searchon=names&keywords=rdap>.

Sunsetting WHOIS is important.  See, for example, the MOBI takeover
and "IANA whois information" (Sept 2024),
<https://groups.google.com/a/mozilla.org/g/dev-security-policy/c/mAl9XjieSkA/m/lF81k0YYAgAJ>.

What do folks recommend on Bookworm?

Jeff
