Questions

CIDR Calculator FAQ

Can I use this tool for IPv6 addresses?
The live page excerpt and stored notes focus on IPv4 CIDR calculations with Class C examples; IPv6 support is not mentioned in the provided material.
What does the prefix length represent in the results?
The prefix length (mask bits) determines the subnet size; for example, a /26 mask provides 62 usable hosts per the sample output showing 192.168.33.64/26.
How do I interpret the network and broadcast addresses shown?
The network address identifies the start of the block, and the broadcast address marks the end; the range between them contains all assignable host IPs.
Is the calculator accurate for non-standard subnet masks?
The tool processes the CIDR prefix length provided; accuracy depends on the input matching the intended network segmentation.
