Regex and subnets

[Keenanix]

Hi all!
Help write a regular expression. You have to filter by url + filter exclude subnets.
For example:
example.com/articles/ and exclude subnets 111.222.333.*  222.333.444.*  222.333.*.*  🤔

Can you provide some example events otherwise we have little chance of giving you any useful response?
