This is not necessarily wrong, I used to have a dialup account where
connections within the UK would go often go to London, then go round a
tour of Western Europe, and then come back through London. Although
there probably is a fault in your case since you can't connect.

I think Point-to-Point links just work like that, with arbitrary
addresses on either end of the link. My address and gateway have only
the first byte in common.

I don't see what name resolution has to do with the delay, the 39ms is
the round-trip time to the gateway at the ISP.
