Just noting it does not match: 001.002.003.000:0012345 Which may be good for some people, bad for others. Even 0.0.0.0 is a valid IP Address for some purposes, and not for others.

you have right, this was early stage of regexp, so everyone should rewrite it.

You don't find valid numbers like 247 with 2[0-5]{2} Should be 2[0-4]\d|25[0-5]
