Network returns a cel.EnvOption to configure extended functions for network address parsing, inspection, and CIDR range manipulation. Note: This library defines global functions `ip`, `cidr`, `isIP`, `isCIDR` and `ip.isCanonical`. If you are currently using variables named `ip` or `cidr`, these fun
