"The core of domain name system (DNS) is the invention of a
hierarchical, domain-based naming scheme and a distributed database
system for implementing this scheme. This allows local control of
segments of the overall database, yet the data is available across
the entire network through a client-server scheme. This database of
domains is maintained by interNIC (Network Information Center).
Robustness and adequate performance are achieved through
replication and caching."
"Program called name server constitutes the server half of DNS's
client-server mechanism. Name servers contain information about
some segment of the database make it available to clients called
resolvers. Resolvers are just library routines that create queries
and send them across a network to a name server...."
"Configuring a DNS server requires several files and databases
to be modified or created. The process is time-consuming, but
luckily has to be done only once for each server. First I'll assume
you already have a copy of the Domain Name Server software. It is
probably called named or in. named depending on your flavor of
