How to Calculate What is My IP Address?
What is What is My IP Address??
An IP address (Internet Protocol address) is a numerical label assigned to each device on a network. IPv4 uses 32 bits (e.g., 192.168.1.1); IPv6 uses 128 bits (e.g., 2001:0db8::1). An IP calculator helps find network address, broadcast, subnet mask, and host range.
Step-by-Step Guide
- 1IPv4: four 8-bit octets (0–255 each), e.g. 192.168.1.100
- 2CIDR notation: /24 means 24 bits for network, 8 bits for hosts
- 3Subnet mask /24 = 255.255.255.0
- 4Hosts per subnet: 2^(host bits) − 2 (subtract network and broadcast)
Worked Examples
Input
IP: 192.168.1.100 / 24 subnet
Result
Network: 192.168.1.0 · Broadcast: 192.168.1.255 · 254 hosts
