AFAIK, this is a configurable parameter in most routers ( CISCO and
Cyclades for sure), also most routers have an other configuration
parameter: the DNS(s) names so if necesary it could do a DNS lookup for
its name stripping the name part and retaining the domain.
Of course real routers have this as a configuration option for that
service apart.
The way this information is stored internally it has no meaning for
that problem.
