"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 Unix."
