feature: Support CIDR notation in IsIP validator #727

Open grimurd opened 4 years ago

grimurd commented 4 years ago

Description

Currently the IP validation fails when a IP subnet using CIDR notation is given.

Example values

192.168.1.1/32
2001:db8::/32

Proposed solution

Add an additional argument to the IsIP validator specifying whether CIDR notation is required, optional or forbidden. Default the argument to forbidden to maintain backwards compatibility.

Optionally the CIDR prefix could be validated. It can only have value 0-32 for IPv4 or 0-128 for IPv6

Hi, we use validator.js internally and they seem to have a isIPRange() validator but it haven't been imported to class-validator yet. Feel free to open a PR

It only support ipv4 so you would also have to open an issue there to ask a feature request for IPv6 range
