The ethers table stores information about the 48-bit Ethernet addresses of workstations on the Internet. It has three columns:
| Column | Content | Description |
|---|---|---|
| Addr | Ethernet-address | The 48-bit Ethernet address of the workstation |
| Name | Official-host-name | The name of the workstation, as specified in the hosts table |
| Comment | Comment | An optional comment about the entry |
An Ethernet address has the form:
n:n:n:n:n:n hostname
where n is a hexadecimal number between 0 and FF, representing one byte. The address bytes are always in network order (most significant byte first).
