No difference whatsoever, as you may have noted
that both hostnames resolve to the same IP address.
Likely they are different folders on the same server.
This would be an example of "name based virtual hosting",
which is possible since the implementation of HTTP 1.1

The server recognizes the browser's request by
name ( and serves from the
web folder configured to receive that request. sends you to some
other folder in the same way, or perhaps it
is unconfigured and sends you instead to the
'default' folder at that site.  Seems unusual that
it would be in DNS and not specifically configured,
but that's a possibility.

You said that already, too.  I feel sorry for them,
maybe  ;-)

Nonetheless, welcome to the world of FreeBSD.
