The networks database associates network names with network numbers, enabling some applications to use and display names rather than numbers. The networks database is based on information in the /etc/inet/networks file. This file contains the names of all networks to which your network connects through routers.
The Oracle Solaris installation program configures the initial networks database. However, if you add a new network to your existing network topology, you must update this database.
The networks(4) man page contains the complete syntax for /etc/inet/networks. The basic format is shown here:
network-name network-number nickname(s) #comment
Official name for the network
Number assigned by the ISP or Internet Registry
Any other name by which the network is known
Any note that you want to append to an entry in the file
You must maintain the networks file. The netstat program uses the information in this database to produce status tables.
A sample /etc/networks file follows.
