Net::MAC is a Perl module for representing and manipulating Ethernet MAC addresses.
I wrote the first version over a few evenings/Saturdays in my spare time, after being driven brutally insane by Cisco’s SNMP representation of MAC addresses. Who uses decimal to represent MAC addresses? Cisco does.
Oliver Gorwits sent some patches for version 1.2, became a co-maintainer shortly after.
I offer my props to the excellent Test::More module.
