✨ ETHERS(5) — Ethernet address to IP number database ✨

🎀 NAME

ethers — the Ethernet address to IP number database, aka the cutest little lookup list 🦋

💖 DESCRIPTION

okay so /etc/ethers is basically a list 📝 of 48 bit Ethernet addresses paired up with their matching IP numbers, with one line for each IP number:

Ethernet-address  IP-number

bestie, the two items just need to be separated by any number of SPACE and/or TAB characters, no drama 💅. A # at the start of a line kicks off a comment that runs to the end of that line, so you can leave yourself notes 🌸. The Ethernet-address gets written as x:x:x:x:x:x, where each x is a hexadecimal number between 0 and ff representing one byte of the address. It's stored in network byte order (big-endian), so keep that in mind 🫶. The IP-number can be a hostname that gets resolved by DNS, or a dot separated number. Both work, periodt ✨.
