Binary masks
Subnet: 11111111.11111111.11111111.11111111
Wildcard: 00000000.00000000.00000000.00000000
The first 32 bits identify the network. The remaining 0 bits identify addresses inside it.

What this result means
A /32 IPv4 network contains 1 consecutive addresses. For /32, point-to-point and host-route rules differ from traditional subnet reservations.
Use the wildcard mask in access lists and routing policy where a device expects inverse mask bits. Always verify vendor syntax before applying generated values to production equipment.
