I'm jumping in here, late, and with no regard to any message that may
have followed this.  Wouldn't this particular problem be resolved by
following the DHCP lease renewal rules: apply for a new lease half way
to expiry?

I haven't ever investigated the SSH protocol, so I could be right out
of turn, but that seems an obvious correction to the problem as Jason
formulated it.

I'll be happy to be corrected and informed.
