I would like some built in functionality to support common tasks associated with working with IPv4 and IPv6 addresses.
For examples of common tasks, I'd personally like to see a function to convert IPv4 to a numeric value and back.
For IPv6, I'd like to see something similar to the inet6_ntoa() and inet6_aton() functions implemented by many other languages, and possibly also the ability to represent them easily in formats required by commonly used geo-location lookup datasets such as Maxmind, etc..
From what I can gather, our best options currently seem to be outlined here on by Chris Hemedingers SAS Dummy blog and on this SAS Community post.
