fuzzyping has asked for the wisdom of the Perl Monks concerning the following question:
I'm trying to match IPv6 addresses and having some difficulty. IPv4 is very standard and predictable, but the address architecture for IPv6 allows for a number of "short-hand" representations. It's entirely possible to see anything from :: to ::1 to 0:0:0:0:0:0:0:0. An example "short-hand" might be to represent FF01:0:0:0:0:0:0:101 as FF01::101.
I expect that I can use /\w*\:\w*\:\w*/ to verify the input line contains an actual IPv6 address, but I'll need to be able to extract the address. What could I use that would match 0:0:0:0:0:0:0:0 as well?
Thanks!
