Question

I’m trying to see if a string is an IP address. Since IPv6 is rolling out it’s better to support that too, so to make it simple, i just want to replace anything that isn’t a dot or a number.

I found this regex on stackoverflow by searching:

\d+(?:\.\d+)+

but it does the opposite of what i want. Is it possible to inverse that regex pattern?

Thanks!

Try the following:

[^.0-9]+

Matches anything that is not a dot or a number
