list of hosts on network
The file /etc/hosts is a list of hosts that share
the network, including the local host. It is referred to
by programs that need to translate between host names and
Internet addresses when the name server
is not being used. Each line in the file describes a
single host on the network and consists of three fields
separated by any number of blanks or tabs:
address name aliases ...
The routines which search this file ignore comments
(portions of lines beginning with ``#'') and blank
The Internet address. Unless another
type of address is required by some host on the network,
address should be a Class A address, which takes
the form net.node where net is the
network number from /etc/networks (see
which must be between 0 and 127; and node is a
value which must be unique for each host and be between 0
The fully qualified domain name of the host
(for example, grinch.eng.xyz.com).
A list of alternate names for the host (such as the unqualified node name).
Aliases can be used in network commands in place of the node name.
Internet addresses can actually take one of four forms:
A is a simple 32-bit integer.
A is an eight-bit quantity occupying the high-order byte
and B is a 24-bit quantity occupying the remaining bytes.
This form is suitable for a Class A address of the form
A is an eight-bit quantity occupying the high-order byte;
B is an eight-bit quantity occupying the next byte;
and C is a 16-bit quantity occupying the remaining bytes.
This form is suitable for a Class B address of the form
The four parts each occupy a byte in the address.
