/14 Subnet: Mask 255.252.0.0, 262,142 Usable Hosts

A /14 subnet has a subnet mask of 255.252.0.0 and contains 262,144 total IP addresses, of which 262,142 are usable host addresses (the network and broadcast addresses are reserved). A /14 contains 1,024 /24 networks.

Usable hosts in a /14 by platform

Cloud providers reserve more than the usual two addresses per subnet, so the same /14 gives you fewer usable IPs in the cloud than on a standard LAN.

Good to know

A /14 subnet has a 255.252.0.0 mask and 262,144 total addresses (262,142 usable). Each step from /14 to /15 halves the block; each step back to /13 doubles it.

How a /14 is calculated

• The /14 means the first 14 bits are the network portion, leaving 18 host bits.
• Total addresses = 2^(32 - 14) = 2^18 = 262,144.
• Usable hosts (standard) = 262,144 - 2 (network + broadcast) = 262,142.
• Subnet mask = 255.252.0.0; wildcard mask = 0.3.255.255.
