.SH "NAME"

.SH "SYNOPSIS"

.Vb 1
\&    use Net::Domain qw(hostname hostfqdn hostdomain domainname);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Using various methods \fBattempt\fR to find the Fully Qualified Domain Name (\s-1FQDN\s0)
of the current host. From this determine the host-name and the host-domain.
.PP
Each of the functions will return \fIundef\fR if the \s-1FQDN\s0 cannot be determined.
.SS "Functions"

.ie n .IP """hostfqdn()""" 4
.el .IP "\f(CWhostfqdn()\fR" 4
.IX Item "hostfqdn()"
Identify and return the \s-1FQDN\s0 of the current host.
.ie n .IP """domainname()""" 4
.el .IP "\f(CWdomainname()\fR" 4
.IX Item "domainname()"
An alias for \fIhostfqdn()\fR.
.ie n .IP """hostname()""" 4
.el .IP "\f(CWhostname()\fR" 4
.IX Item "hostname()"
Returns the smallest part of the \s-1FQDN\s0 which can be used to identify the host.
.ie n .IP """hostdomain()""" 4
.el .IP "\f(CWhostdomain()\fR" 4
.IX Item "hostdomain()"
Returns the remainder of the \s-1FQDN\s0 after the \fIhostname\fR has been removed.
