May want to out a warning on this tool that if your checking against a long list of strings you may want to use something else. A massive regex can be a huge performance bottleneck. I know from personally killing a production server by using an inefficient regex on large strings of data.

list2regexp will limit each regular expression to matching 10,000 entries by default. Matching against each pattern of 10,000 entries takes around 1 microsecond on a laptop. I've fed it several megabytes of IP addresses and it doesn't choke. That's kind of the point.
