Unix/Linux/MacOSx : Get local IP address
Problem :
How to find out my MacOSX/ Linux / UNIX system ip address, subnet and related networking information from a command prompt?
Solution :
Use this command :
ifconfig
- Ifconfig is used to configure the network interfaces during boot time.
- If no arguments are given to ifconfig command it displays the status of the current active interfaces.
- It displays Ethernet IP address, Mac address, subnet mask and other information.
- ifconfig tool is available to all *nix based OS.
Example output :
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
options=3<RXCSUM,TXCSUM>
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
inet 127.0.0.1 netmask 0xff000000
inet6 ::1 prefixlen 128
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
stf0: flags=0<> mtu 1280
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
