An IP subnet calculator determines network address, broadcast address, usable host range, and total hosts from an IP address and CIDR notation (e.g. 192.168.1.0/24).
Formel
- n
- first n bits are network — first n bits are network
Trin-for-trin guide
- 1CIDR /n = first n bits are network, rest are host bits
- 2/24 = 256 total addresses (254 usable)
- 3Subnet mask: /24 = 255.255.255.0
- 4Usable hosts = 2^(32−n) − 2
