192.168.0.0/16: The Home Network Range

192.168.0.0/16 is the smallest RFC 1918 private range: 65,536 addresses from 192.168.0.0 to 192.168.255.255. Nearly every home network in the world uses a /24 from it.

Is an address inside 192.168.0.0/16?

Yes — 192.168.88.1 is inside 192.168.0.0/16. It is address number 22,529 in the block (counting from 0).

What 192.168.0.0/16 is

It holds 256 /24s: 192.168.0.0/24 up to 192.168.255.0/24. Consumer routers each pick one of these as their LAN.

The low numbers (0, 1, 2, 10, 50, 88, 100) are taken by router defaults far more often than high ones, so picking something like 192.168.173.0/24 reduces the chance of a clash.

Who uses it

  • Home and small-office routers

    192.168.0.x and 192.168.1.x are the most common; MikroTik uses 192.168.88.1 and many mesh systems use 192.168.4.x, 192.168.68.x or 192.168.86.x.

  • Kubernetes with Calico

    Calico's default pod CIDR is the entire 192.168.0.0/16. On a cluster whose nodes are on 192.168.x.x, pods and nodes overlap unless you change it.

Conflicts and gotchas

  • Calico default pool. Installing Calico with defaults on nodes in 192.168.1.0/24 makes pod routes shadow the real LAN. Set a different pod CIDR at install time. See the pod CIDR calculator.
  • Using the whole /16 in a firewall rule. It covers every home network of every VPN user too.
  • Office networks in 192.168. Remote users at home are almost certainly on a 192.168 /24. If the office uses one too, some of them will clash. Use 10.x or 172.16.x for businesses.

How to split 192.168.0.0/16

Worked example: into /24s

  1. Going from /16 to /24 borrows 24 − 16 = 8 bits from the host part.
  2. Each borrowed bit doubles the number of subnets: 28 = 256 subnets.
  3. Each /24 keeps 32 − 24 = 8 host bits: 28 = 256 addresses, so 254 usable after removing network and broadcast.
  4. The new mask is 255.255.255.0, so subnets step by 1 in the third octet: 192.168.0.0/24, 192.168.1.0/24, 192.168.2.0/24 … up to 192.168.255.0/24.
Ways to split 192.168.0.0/16
