# /14 Subnet Mask ReferenceIPv4

Four tidy /16s under one summary: that is a /14, masked 255.252.0.0, with 262,142 usable addresses. Long-lived institutions often hold several adjacent /16s that summarize into exactly this shape.

The /14 subnet mask is 255.252.0.0, equivalent to 0.3.255.255 as a wildcard. A /14 block contains 262,144 IP addresses (262,142 usable hosts).

- **Block size:** 262,144 addresses (218)
- **Typical role:** Large enterprise and carrier aggregation

## Example /14 networks

Three consecutive /14 blocks, starting at the /14 boundary that contains 198.51.100.0:

| Network | Usable range | Usable hosts |
| --- | --- | --- |
| 198.48.0.0/14 | 198.48.0.1 – 198.51.255.254 | 262,142 |
| 198.52.0.0/14 | 198.52.0.1 – 198.55.255.254 | 262,142 |
| 198.56.0.0/14 | 198.56.0.1 – 198.59.255.254 | 262,142 |

## How to calculate a /14 mask

A /14 mask sets the first 14 bits of a 32-bit number to 1 and leaves the remaining 18 bits as 0. In binary that reads `11111111.11111100.00000000.00000000`, which converts to dotted decimal `255.252.0.0`. Each block covers a contiguous run of 218 = 262,144 addresses, and every block starts at a multiple of that size. The wildcard simply flips every bit, giving `0.3.255.255`.

## Where /14 is used

- Summarizing four neighboring /16 campus or agency blocks at the border.
- Hierarchical enterprise addressing with one aggregate per business unit.
- Registry-style block bookkeeping and audit documentation.

Example: 140.80.0.0/14 covers 140.80.0.0 through 140.83.255.255. Alignment check: the second octet of any /14 must be a multiple of four.

## Frequently asked questions

**What is the subnet mask for /14?**

255.252.0.0, wildcard 0.3.255.255, which fixes six bits of the second octet.

**How many hosts are in a /14?**

262,142 usable of 262,144 total addresses.

**How many /16s combine into a /14?**

Four, provided they are consecutive and the starting second octet is divisible by four.
