in thread How to increment a MAC Address?

The components of a MAC address, when expressed as a group of six octet values, are expressed as hexadecimal values (eg. FE:DC:BA:01:23:45) - Your code does not account for this with the maximal octet value of 99 (decimal) provided by your code.

Although in stating this, I should note that this is a problem too with the problem description in the original thread post.

perl -le "print unpack'N', pack'B32', '00000000000000000000001000000000'"

yes, i know 99 is not valid, just that im simulating something out here, where i require the value as 99 and not in hex.	[reply]

if $_ holds your string, then this should increment it `$_ = join ":",unpack "A2"x6, substr( ('0' x 12 . (1 + join '',split /:/,$_))), -12)` [download]	[reply] [d/l]
