Examples

IP address / CIDR / netmask

IPv4 or IPv6, with or without a prefix — 10.0.0.0/8, 2001:db8::/48, or a dotted netmask like 192.168.1.0 255.255.255.0. A bare address means one host (/32 or /128).

192.168.0.0/24 gives 254 usable addresses, 192.168.0.1 to 192.168.0.254, with broadcast 192.168.0.255 and mask 255.255.255.0. Many routers ship with it as the default LAN.

The addresses

192.168.0.0 is the network address and 192.168.0.255 the broadcast; neither can be given to a device. The remaining 254 addresses are hosts. The mask is 255.255.255.0, the wildcard 0.0.0.255.

Routers that use this network typically take 192.168.0.1 as the gateway and run a DHCP pool over part of the range, for example .100 to .199, leaving the rest for static devices. Nothing in the standard requires the gateway to be .1; it is convention.

Common problems

Double NAT: when an ISP modem and your own router both default to 192.168.0.x, plugging one behind the other either fails (same subnet on both sides) or works with two layers of NAT that break port forwarding. Move one of them to a different third octet.

If you set a static IP, keep it outside the DHCP pool or reserve it in the router; otherwise the router may lease the same address to another device and both lose connectivity intermittently.

Neighbours and alternatives

Its neighbour 192.168.1.0/24 is the other very common default; the two together make 192.168.0.0/23. Splitting this /24 into two /25s or four /26s gives separate segments for IoT or guests. For a network that VPN users must reach, prefer a less common 10.x block over either default.

Subnet math for this /24

With mask 255.255.255.0, any address from 192.168.0.0 to 192.168.0.255 is on-link and anything else, including 192.168.1.x, goes to the gateway. That is why a device statically set to 192.168.1.50 on this network cannot talk to its neighbours even though the addresses look close: they sit in different /24s.

Paste a device's address and mask into the calculator when it refuses to connect; a mask of 255.255.0.0 or a typo in the third octet shows up immediately in the network address.

FAQ

Questions, answered.

Tap a question to expand the answer.

What is the usable range of 192.168.0.0/24?

192.168.0.1 to 192.168.0.254: 254 addresses. 192.168.0.0 is the network and 192.168.0.255 the broadcast.

Can I use 192.168.0.0 as a device address?

No. In a /24 it is the network address. The first assignable address is 192.168.0.1.
