.el .IP "($hostname, \f(CW$domain\fR) = split_domain ($fqdn)" 4
.IX Item "($hostname, $domain) = split_domain ($fqdn)"
Cut a fully-qualified hostname into the hostname part and the domain
part, splitting at the \s-1DNS\s0 registry boundary.

.Vb 2
\&    "www.foo.com" => ( "www", "foo.com" )
\&    "www.foo.co.uk" => ( "www", "foo.co.uk" )

Cut a fully-qualified hostname into the hostname part and the domain
part, returning just the domain.

Return \f(CW1\fR if the domain is valid, \f(CW\*(C`undef\*(C'\fR otherwise.  A valid domain
(a) does not contain whitespace, (b) contains at least one dot, and (c)
uses a valid \s-1TLD\s0 or ccTLD.
