MAC.address - Find, Validate and Identify Device MAC Addresses

Tools to work with MAC (Media Access Control) addresses: list the MAC addresses of the local network interfaces and of the neighbors in the ARP cache on Linux, macOS and Windows, extract MAC addresses from free text, validate and normalize their notation, check the multicast and locally administered bits, generate random addresses, derive IPv6 interface identifiers (modified EUI-64), and identify the manufacturer using the public IEEE (Institute of Electrical and Electronics Engineers) MA-L, MA-M and MA-S registries <https://regauth.standards.ieee.org/standards-ra-web/pub/view.html#registries>.
