anyone knows how looks _good_ ip adress regexp ? I use something like:
(\d{1,3}\.){3}\d{1,3}
but that also matches for example 888.777.444.222, which is of course not good ip adress.
What's your definition of a "good" IP address? Do you care about correct DNS, do you care about whether the address is in use?
To me, this test comes to mind:
sub goodIP { gethostbyaddr pack('C4', split /\./, shift), 2 }
print "Good IP address\n" if goodIP('11.22.33.44');I don't want use any module for this,
Why?
I only want fing proper regular expression for IPs.
You'd better define "good".
