I always recommend debugging using the simplest query possible, as close
to the source of possible confusion aspossible.  I also recommend not
making assumptions, even things you think you know must be true.

Given that we have implicated, but not 100% reliably, a change in
gethostname(3), it seems clear that Mario should run hostname(1) on this
computer when it is in various places on the network, and actually see
what values are printed.

I have observed that hosts that use dhcp often set the hostname based on
the domain name provided by the DHCP server.  I have no idea if that is
happening, but it is certainly likely enough that checking is warranted.
