- Input
- 192.168.1.10/24

CIDR /24 explained
/24 is the most recognizable prefix in small IPv4 networks because it aligns exactly three network octets.

Numbers in a /24 network
- The /24 mask is 255.255.255.0. In traditional IPv4, 8 host bits remain.
- That creates 256 total addresses; in common networks, 254 are usable by hosts.

Mask
- Input
- /24
- Expected output
- 255.255.255.0
Often informally called a class C mask.
Frequently asked questions
Does /24 always have 254 hosts?
In traditional IPv4 unicast, yes: 256 addresses minus network and broadcast.
Can I split a /24 with VLSM?
Yes. The tool can allocate smaller subnets inside the base block.
