pub fn parse_net(entry: &str) -> Result<IpNet>Expand description
Parses one allow-list entry as a network.
Accepts both CIDR notation (192.168.1.0/24, fd00::/8) and a bare address
(203.0.113.7), the latter becoming a host route — writing a /32 for a
single machine is noise an operator should not have to remember.
