It's not as simple as that. You first need to reliably determine whether it's an IPv4 or IPv6 address (both contain . and : which is generally used for this test), and whether it's IPv4 or IPv6, that will determine how to strip off the port (such as using Regexp::Common for example)... Once you know for certain that you're dealing with an IPv4 OR an IPv6 address, yes, it's easy to strip the port off. I guess the question wasn't clear then. How would you differentiate between a IPv4:port and IPv6.port, as both contain the same set of numbers. Assuming IPv4 is decimal only also won't work as 1:2:3:4::1 is also a perfectly legitimate IPv6 address. Would need to be some kind of regexp checking the amount of "." vs. the amount of ":" characters I guess. IPv4 = 3 dots + 1 colon, whilst IPv6 = at least two colons and one dot. Once you know whether you're dealing with IPv4 or IPv4, a simple split() would be enough to cut the port... The question is more towards determining reliably what you're working with. -- Chris.
