Synopsis:
$convert(<ip address|hostname>)
Technical:
This function does a DNS lookup on the given address. For an IP address,
it attempts to find the corresponding Internet hostname. For a hostname,
it attempts to find the corresponding IP address.
Practical:
This function does effectively the same thing as $ iptoname () and
$ nametoip (). It is mostly useful when you want to convert an address,
but you aren't sure if the input will be an IP address or not.
Returns:
IP address or hostname corresponding to input, or nothing on error
Examples:
$convert(some.school.edu) returns IP address for "some.school.edu"
$convert(192.168.1.1) returns hostname for "192.168.1.1"
See Also:
iptoname (6); nametoip (6)
