hosts - hostname to IP address database
The hosts database lists the IP addresses and the hostnames that
translate to these IP addresses. It is used by nonamed(8) in a network
without name servers. A simple /etc/hosts may look like this:
The localhost entry lists a special address that refers to the local host
itself (a kind of /dev/tty for hosts.) You should only list it if
nonamed needs it! The other entries are actual machines. The file may
contain comments marked with '#'.
You can have aliases (more hostnames on the same line), but it is not
recommended, because nonamed can't present them to the system as CNAME
records. An often seen form like
184.108.40.206 darask.home.cs.vu.nl darask
is harmless though, and has the small advantage that you can use the
short name in /etc/ethers so rarpd can match it at boot time.
