The problem is i am not able to find appropriate regex for this pattern.

Answer 1

I would suggest to not solve all problems with one regular expression.

It seems that your initial string contains values that are separated by ",". So split those values with ",".

Then iterate the output of that process; and "join" those elements that are IP addresses (as it seems that this is what you are looking for).

And just for the sake of it: keep in mind that IP addresses are actually pretty complicated; a pattern "to match em all" can be found here
