Use ifconfig command to configure a network interface as well as to display information such as ip address, netmask etc:
Code:
ifconfig -a
/sbin/ifconfig 
/sbin/ifconfig eth0
ifconfig | less
Output see 2nd line, look for Word Mask:
Code:
eth0      Link encap:Ethernet  HWaddr 00:30:48:5A:BF:46
          inet addr:10.5.123.2  Bcast:10.5.123.63  Mask:255.255.255.192
          inet6 addr: fe80::230:48ff:fe5a:bf46/64 Scope:Link
