What the heck is this supposed to do?
This piece of code tries to resolve <ipAddress> as numerical IPv4 addre=
ss *or*=20
a DNS hostname.

If you want to check that a string is a valid IP address, call inet_pto=
n(). If=20
you want to check that an IP address is assigned to the system, create =
a=20
socket and bind to that address.
