ipv6 subnet calculator
The calculator opens directly in IPv6 mode so you can enter a prefix and quickly see the network, address range and block size.
2001:db8::/32 is reserved for documentation.
Common range for private IPv6 networks.
Yes. It helps visualize the main subnetting outputs for both IPv4 and IPv6, including split scenarios and more detailed planning workflows.
No. IPv6 uses CIDR prefixes such as /64 or /48.
/64 is the common IPv6 LAN subnet size, especially for SLAAC compatibility.
All calculations run locally in your browser. Nothing is sent to the network or to external services.
