Why Choose Our IP Tools?
Accurate CIDR Calculator
Easily calculate network addresses, broadcast addresses, and the number of usable hosts for any IPv4 CIDR block. Perfect for network planning and routing.
IPv4 & IPv6 Bridge
Seamlessly convert legacy IPv4 addresses into IPv4-mapped IPv6 formats (e.g. ::ffff:192.0.2.1), and extract original IPv4 data from IPv6 mapped strings.
Massive Range Counting
Powered by BigInt engines, our tool can calculate the exact number of IPs between any two addresses, even supporting astronomical numbers in IPv6 networks.
