thanks.
Post by Fabian Santiagomay i ask, what are all of the CNAMEs for the pool? Thanks.
Nobody knows for sure. There can be arbitrary names.

Beware that for port 11371 traffic, you must be able to handle
requests with any Host: header, for the various pools and CNAMEs which
exist, and you must accept requests with no User-Agent: header set, as
at least one major OpenPGP HKP client refuses to set a User-Agent
field when talking to keyservers.
You don't need to accept unknown names on ports 80/443.

and also "keys.gnupg.net", which points to one of those.
Other people can set up their own CNAMEs; Kristian's service is widely
used, including by gnupg.net, but not in any way especially privileged.
