1. Lazy way:

Code:

$ grep '192.168.' /directory/*

2. Specific way:

Code:

$ export IP4a='192.168.\b((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){1}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b'

$ grep -E "$IP4a" /directory/*

3. Perfect way (any ip, but only ip4):

Code:

$ export IP4='\b((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b'

$ grep -E "$IP4" /directory/*

This was to be an example which you would need to replace with the directory YOU want to use.
