MacTools

MacTools is a MAC-centric library for aiding in network handling and automation.

Full test coverage and fully type annoted.

Installation

This is a publicly available library on PyPI and can be installed with:

pip install mactools

Features

MacAddress

MAC object similar to Python's ipaddress library. Performs validation on creation and allows quick and easy format changing for the user. Accepts EUI-48 and EUI-64 formats.

Usage

Built-in MacAddress attributes allow for conversion between the common formats of either delimiters, decimal, or binary. Such as:

from mactools import MacAddress
mac = MacAddress('00:11:22:AA:BB:CC')

# returns the MAC without an delimiters or spaces (001122AABBCC)
mac.clean

# returns the MAC with period delimiters (0011.22AA.BBCC)
mac.period

# returns the decimal/numeric form (73596058572)
mac.decimal

# returns the OUI (00:11:22)
mac.oui

The full format list includes: clean, colon, period, hyphen, space, oui, decimal, binary

IPv6 Support

This library has some methods for simplifying IPv6 SLAAC-based address creation:

# returns the IPv6 Suffix/Interface ID in EUI-64 per RFC 4291 (0211:22ff:feaa:bbcc)
mac.eui64_suffix

# returns the Link-local address (fe80::0211:22ff:feaa:bbcc)
mac.link_local_address

# returns a Global Unicast Address (2001:db8::) as `ipaddress.IPv6Address`
mac.get_global_address('2001:db8::0211:22ff:feaa:bbcc')

OUICache

Local cache of the IEEE OUI MA-L, MA-M, and MA-S registries for quick look-ups without needing to consistently hit API endpoints for individual queries.

MacAddress currently automatically performs the look-up on creation.

The full information is available, including OUI, Vendor, Address, etc.

The cache also contains specific references to commonly defined non-vendor OUIs such as Multicast, IEEE protocols (STP, LLDP, etc), Locally administered and others.

Usage

Intakes a string MAC/OUI or MacAddress object for either vendor or full record from the IEEE OUI MA-L registry. The cache will be built if one is not present (or if manually prompted) or the version of the code has changed.

from mactools import get_oui_cache

# the `mac` defined above already has the look-up performed and recorded on creation, if the record was found

vendor = mac.vendor

cache = get_oui_cache()
oui = '01000C'

# These methods would also work with the `mac` defined above as well 
vendor = cache.get_vendor(oui)

vendor will be the string of vendor registered to IEEE. It will also identify common protocol MACs (such as Spanning Tree, Cisco/Extreme, etc.) and randomized MACs (locally administered).
