Finding static IP of server [closed]

Question

I have access to a server via its local IP (I use putty) and I know the server has a static IP, how can I found its static(fix) IP? Its OS is CentOS.

Look at the edge router/firewall configuration? Hit whatismyip.com from the server in question? — voretaq7, Nov 27, 2012 at 21:25

Enter ifconfig at the command line.

Note that ifconfig will show the actual IP address assigned to the network interface, where the external sources listed in comments/answers will show the IP as it appears to, er, those external sources. This may be different in some situations, so check both.

For example:

links -dump http://whatismyip.com | egrep "([0-9]+.){3}"

Of course you can use another site, but this is one of most popular.

I assumed that there is some kind of NAT, and public IP is not known on host itself
