About /14 Networks
Medium-to-large enterprise allocation. A /14 subnet uses the mask 255.252.0.0 and provides 262,142 usable host addresses out of 262,144 total IPs.

Splitting a /14 Into Smaller Subnets
A /14 divides evenly into any longer prefix. Each row shows how many subnets of that size fit inside one /14, and how many usable hosts each of them carries.

| /15 | 2 × /15 | 255.254.0.0 | 131,070 |

Frequently Asked Questions
What is a /14 subnet?
A /14 subnet uses the subnet mask 255.252.0.0 with 262,142 usable host addresses and 262,144 total IP addresses. It has 14 network bits and 18 host bits.
How many hosts in a /14 network?
A /14 network supports 262,142 usable hosts out of 262,144 total IP addresses. The usable range excludes the network address and broadcast address.
What subnet mask does /14 use?
A /14 subnet uses the mask 255.252.0.0 (wildcard mask 0.3.255.255). This means the first 14 bits identify the network and the remaining 18 bits identify hosts.
How many /16 subnets are in a /14?
One /14 splits into 4 /16 subnets, each with mask 255.255.0.0 and 65,534 usable hosts. Every prefix longer than /14 divides it evenly — the full table is above.
How many /14 subnets are in a /13?
A /13 holds 2 /14 subnets. Each step to a shorter prefix doubles that count, because one bit moves from the host portion of the address to the network portion.
Standards
The figures on this page follow from the following specifications rather than from convention.
- RFC 4632 — Classless Inter-Domain Routing (CIDR)
Defines the /14 prefix notation used throughout this page, and the address-aggregation model that replaced classful addressing.
- RFC 950 — Internet Standard Subnetting Procedure
The original definition of the subnet mask, and of the network and broadcast addresses excluded from the usable host count.
- RFC 1918 — Address Allocation for Private Internets
Reserves 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16, the ranges most /14 subnets are carved from in practice.
