Nico isn't understanding the original question :-)

Martin's laptop is travelling, and he want to be able to SSH *to* the
laptop.  So "DHCP telling the laptop where it is" is not the answer to
"how does the outside world know where to reach the laptop".

DynDNS is one approach, or "have OpenSSH query 3 different FQDNs
and try to connect to them in sequence" (which was the original question).
