[CALUG] vim regex challenge

[Jim Bauer]

Try this

s/\.\d\{1,3}\.\d\{1,3}$//

Match '.', followed by 1-3 digits, followed by a '.' followed by 1-3 
digits at the end of the line.  You only need to escape the { not the }.
If you leave out the '$' it'll match and remove the first 2 octets 
instead of the last 2.

This is matching a '.', followed by a digit (\d), followed by anything 
up to end-of-line.  The '*' is greedy so it always matches as much as 
possible.

This is matching a '.', followed by 1-3 digits, followed again by 
anything up to end-of-line.
