FAQ
What is the difference between CIDR and subnet mask?
CIDR uses a prefix length (e.g. /24) to define the network range, which is equivalent to a subnet mask (e.g. 255.255.255.0). CIDR is more concise.
Does it support IPv6?
Yes. It handles IPv6 expansion, abbreviation, and prefix calculations.
Is my data sent to a server?
No. Everything runs locally in your browser and nothing is uploaded.
