What is Name Servers
A name server is an Internet host running software capable of processing DNS requests. A popular free software name server is BIND Named, for UN*X hosts.
Primary and Secondary Name Servers
Typically, a single name server will be configured as the primary name server for a domain. For backup purposes, a number of other name servers may be configured as secondary name servers. From the standpoint of DNS, there is no difference between primary and secondary name servers, since the resolving algorithm simply uses a domain's NS records in the order provided. Typically, the primary name server is listed first, followed by the secondary, but this is not a requirement. In fact, if a group of domains is served by a set of name servers, the ordering of the name servers may be mixed among the domains, to facilitate load balancing.
A domain's primary name server will have a file on disk containing the RR definitions for that domain. Typically, secondary name servers do not have to be known to the primary. However, some sites, not wishing to publicly distribute copies of their entire domain, restrict zone transfers to preconfigured hosts. Secondary name servers depend on zone transfers for their operation.
Typically, a secondary name server will perform a zone transfer to acquire a complete copy of the primary's RR database, often saving this copy on disk. Periodically, the primary's SOA record for the domain is checked for changes in its SERIAL field. Upon detecting a change, the secondary performs another zone transfer to acquire the updated information. Therefore, the SERIAL field in a domain's SOA record must be changed every time a change is made within the domain.
The timing of secondary updates is governed by several fields in the domain's SOA record. The secondary check the primary's NS record every REFRESH seconds. If one can not perform a scheduled check, it retries every RETRY seconds. If a check can't be performed for EXPIRE seconds, then all the secondary's records for that domain are discarded, and it begins to return errors to lookup requests.
