NAME
       domainname - set or display name of Network Information Service domain

SYNOPSIS
       [name_of_domain]

DESCRIPTION
       Network	Information  Service  (NIS) uses domain names to refer collectively to a group of hosts.  Without an argument, domainname displays
       the name of the NIS domain.  Only superuser can set the domain name by providing name_of_domain.  The domain name is  usually  set  in  the
       configuration file by setting the variable.  The name_of_domain is normally a valid Internet domain name.

DEPENDENCIES
       NIS servers use the NIS domain name as the name of a subdirectory of Therefore, name_of_domain cannot be a or and it must not contain Since
       the NIS domain name can be as long as 64 characters, name_of_domain may exceed the maximum file name length allowed on a given file system.
       If that length is exceeded, the subdirectory name becomes a truncated version of the NIS domain name.

       The  first  14 characters of all NIS domains on the network must be unique; truncated names should be checked to verify that they meet this
       requirement.
