Hello, I'm registering an issue because I need something while using zod-mock.
It would be nice to have support for z.string().ip().

In my project, I have ip type support via the mockeryMapper function,
but it would be more comfortable to have it built into the library.

With your permission, I would like to register a PR to address this issue.
