IPv6 Range to CIDR
IPv6 Range to CIDR Converter
Convert an IPv6 address range to CIDR notation if possible.
How It Works
The tool analyzes the binary representation of start and end addresses to determine if they form a valid CIDR block and calculates the prefix length.
Understanding Results
If the range forms a valid CIDR block, the notation is shown. Some ranges may require multiple CIDR blocks to represent.
