Sed match exact

Question

I'm currently using 's/string/new_string/g' to go through some CSV files, however I'm running into difficulty in the following scenario:

I want to replace instances of '192.168.0.11', however it's also catching instances of '192.168.0.111'.

How can I ensure sed only grabs '192.168.0.11' and not '192.168.0.111'? I'll obviously have to repeat this for many variables, so something easily scalable would be appreciated.

Thanks!

I'm not sure what the regex you are using is, but if you want an exact match of '192.168.0.11' you can use: s/\<192\.168\.0\.11\>//g

The \<\> force an exact match.
