Hello, is there a way to define your own regex character class, such as [[:digit:]].
So, I would, for example, define a regex:

/\b(?:[[:digit:]]{1,3}\.){3}[[:digit:]]{1,3}\b/

and assign it to a:

[[:ipv4:]]

Is it possible to do something like that?

and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
