Tools to Work with Media Access Control ('MAC') Addresses

Description

A media access control address (MAC address) of a device is a unique identifier assigned to a network interface controller (NIC) for communications at the data link layer of a network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and Wi-Fi. In this context, MAC addresses are used in the medium access control protocol sublayer. Tools are provided to work with these 'MAC' addresses.

What's Inside The Tin

The following functions are implemented:

as_raw_mac: Convert a charactrer vector of MAC addresses to a 'list' of 'raw' vectors.
canonicalize_mac: Converts a character vector of MAC addresses into canonical form
is_canonical_mac: Test if MAC address strings are in canonical form
mac_match_age: Lookup ages of MAC addresses
mac_match_registry: Lookup registry metadata of MAC addresses
mac_to_binary_string: Convert MAC address character vector to a binary string representation
rebuild_search_tries: Rebuild in-memory search tries
update_mac_age_db: Update MAC Address Age Database
update_registry_data: Update registry data

The following datasets are included:

mac_age_db: MAC Age Database
mac_registry_data: MAC Registry Data
