If the IP address does not match the one listed by your hostname, you will need to manually update it to get your service working again.
The Domain Name System brought a method of distributing the same address information automatically online through recursive queries to remote databases configured for each network, or domain.
Even this DNS facility still used static lookup tables at each participating node.
