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 secondaries, 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 secondaries 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.
