For each host on an Ethernet, a single line should be present with the following information: Ethernet-address official-host-name Items are separated by any number of blanks and/or TAB characters. A `#' indicates the beginning of a comment extending to the end of line. The standard form for Ethernet addresses is ``x:x:x:x:x:x'' where x is a hexadecimal number between 0 and ff, representing one byte. The address bytes are always in network order. Host names may contain any printable character other than a SPACE, TAB, NEWLINE, or comment character. It is intended that host names in the ethers file correspond to the host names in the hosts(5) file. The ether_line() routine from the Ethernet address manipulation library, ethers(3N) may be used to scan lines of the ethers file. FILES /etc/ethers SEE ALSO ethers(3N), hosts(5) NOTES The Network Information Service (NIS) was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same; only the name has changed. 19 October 1987 ETHERS(5)
