Common Questions
What is CIDR?
Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and IP routing. It uses a suffix (e.g., /24) to indicate how many bits represent the network prefix.
Does this tool support IPv6 compression?
Yes. The IPv6 calculator can take a full address and show its compressed form (using double colons ::), as well as the full expansion.
Is my network data safe?
Absolutely. All calculations (sorting, subnet math) happen locally in your browser. No IP addresses or network data are sent to our servers.
