It looks like your complicated script just acts on the last search match, just like gn does built-in.

If you're going to bring regex into it, just do /\%(\d\{1,3}\.\)\{3}\d\{1,3} (or use ? instead of / if the match you want is before the cursor) and use ygn, dgn, cgn, etc. to operate on the match (in Vim 7.3.610 or higher). Then you can do it again with ygn to get the NEXT match, or if you deleted it or changed it or something the entire action is repeatable with '.'.

Example, using text:
--------------------
Mine: 192.168.1.101
Yours: 192.168.1.102
--------------------

Place cursor on "Mine". Type /\(\d\+\.\)\{3}\d\+ to select (very loosely) the first IP. Type dgn and then type either dgn again or just . (repeat command) to delete both IP addresses. Yes, I know this toy example could be easily done with :s. But more complicated examples very quickly get to the point where recording a simple macro using gn or gN is much easier than piecing together a complicated regular expression/substitute string for an :s command.

As Gary said, this depends on Vim 7.3.610 or higher. Thanks VERY much to Christian Brabandt for this great feature! I probably use it daily.
