NAME
       defaultdomain - specify host's domain name

SYNOPSIS
       /etc/defaultdomain

DESCRIPTION
       The  file  /etc/defaultdomain  determines  a host's domain name for direct use by the NIS and NIS+ name services. The defaultdomain file is
       read at boot time and its contents used by the domainname(1M) command. Because of its use by domainname, defaultdomain is also used by  the
       LDAP  service  (see ldap(1)). Under certain, narrow circumstances (see resolv.conf(4)), because domainname uses defaultdomain, a DNS client
       can use the contents of defaultdomain.

       The contents of defaultdomain consists of a single line containing a host's domain name.

SEE ALSO
       NIS+(1), uname(1), ldapclient(1M), nisclient(1M), ypbind(1M), ypinit(1M), resolv.conf(4)

NOTES
       The defaultdomain file is created and modified by Solaris installation and configuration scripts. Only users knowledgeable of name  service
       configuration should edit the file.
