Subnet Calculator ની ગણતરી કેવી રીતે કરવી
Subnet Calculator શું છે?
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.
સૂત્ર
Network address = IP AND subnet mask; Host count = 2^(32−prefix)−2; CIDR = /24 means /24 prefix bits
- IP
- IP address (IPv4 dotted decimal)
- SM
- Subnet mask (dotted decimal or /prefix)
- n
- Number of usable hosts

- 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
Worked Examples
ઇનપુટ
10.0.0.0/8
પરિણામ
Network: 10.0.0.0; Broadcast: 10.255.255.255; Hosts: 10.0.0.1–10.255.255.254 (16,777,214 hosts)
Frequently Asked Questions
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.
