NAME
       domainname - display or set the name of the current NIS domain for this system

SYNOPSIS
       domainname [nameofdomain]

DESCRIPTION
       The  domainname	command, when used without an argument, displays the name of the current domain. When used with argument, sets the current
       Network Information Service (NIS) domain name to the specified domain name.

       A domain is a logical grouping of networked-connected systems established for the purpose of sharing  a	common	set  of  NIS  data  files.
       Domains are only used by NIS.

       The  NIS  maps  for a particular domain are stored in the directory /var/yp/domainname on each NIS server.  Each NIS  map contains a set of
       keys and associated key values. For example, in a map called hosts.byname, the host names stored there constitute the keys. The correspond-
       ing internet addresses of each host constitute the associated key values.
