Agreed that this could be achieved by a third party library; and probably already is - but the ipaddress module in Python could also have been one. Therefore I feel it would somewhat complete the already existing networking utilities already included if we were to implement this within the standard library. It is for this reason i also recommend an API that is familiar to people who already use the ipaddress module; as this would be a layer 2 compliment to the existing package.
Happy to discuss,

This is a perfect idea for a third party package to be put on PyPi. Have you looked to see if one exists already?
If, at some point, there is a robust and mature version that is widely used, then it might be worth considering g for the standard library.

Currently in Python 3 we have an ipaddress module which allows easy manipulation of IP version 4 and 6 addresses and networks. Examples of this are getting the packed bytes representation of an address, checking if an address is of a specific type according to the RFC (private, multicast, etc.)
My proposal is that we have something with a similar API for MAC addresses. A lot of these operations that we have for IPv4 and IPv6 addresses are also applicable for MAC addresses. We can take in concatenated, hyphenated or dotted notations. Some of the methods could include packed is_multicast is_broadcast is_universal get_oui
and optionally format outputs
dotted(upper=False) hyphenated(upper=False) concatenated(upper=False)
get_oui could initially just return the OUI part of the address without resolving. However, it is possible that on build of Python we pull down the latest OUIs from IEEE into a python file.
My initial thought if people are in agreement was to have a macaddress.py module. However if the APIs for these are similar enough, perhaps it warrants having a networkaddress.py module that contains both the old ipaddress code and the new macaddress code?
I would be grateful to hear people's thoughts on this.
