କ'ଣ Subnet Calculator?

▾

An IP subnet calculator finds network address, broadcast address, usable host range, wildcard mask, and number of hosts from an IP/CIDR input like 192.168.1.0/24.

PrimeCalcPro provides professional-grade tools trusted by businesses and academics.

ସୂତ୍ର

▾

f(x)Network address = IP AND subnet mask; Host count = 2^(32−prefix)−2; CIDR = /24 means /24 prefix bits

କିପରି Subnet Calculator

▾

1CIDR /n: first n bits = network; remaining bits = host addresses
2Network address: all host bits set to 0
3Broadcast: all host bits set to 1
4Usable hosts = 2^(32−n) − 2

What's a subnet mask?

Defines network portion of IP (mask 1s) and host portion (mask 0s). /24 = 255.255.255.0.

How many hosts in /24 subnet?

2^(32−24)−2 = 2^8−2 = 256−2 = 254 usable addresses (network & broadcast reserved).

What's CIDR notation?

/24 means first 24 bits are network. Shorthand for subnet mask. 192.168.1.0/24 is cleaner than /255.255.255.0.
