सबनेट और CIDR कैलकुलेटर — अक्सर पूछे जाने वाले सवाल

What is a CIDR subnet?

Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and IP routing. It specifies the number of leading bits in the subnet mask (for example, `/24` represents `255.255.255.0`).

What parameters does the Subnet Calculator compute?

Given an IPv4 address and CIDR prefix length, the calculator determines the Network Address, Broadcast Address, Subnet Mask, Wildcard Mask, Usable Host IP Range (first to last), and Total Usable Hosts.

What is a wildcard mask?

A wildcard mask is the bitwise inversion of a subnet mask (where 0 indicates match and 1 indicates ignore), widely used in Cisco access control lists (ACLs) and OSPF routing configurations.

Which CIDR prefixes are supported?

The calculator supports all IPv4 CIDR prefix lengths from `/0` (the entire Internet) through `/32` (a single host), detailing special handling for `/30` and `/31` point-to-point links.

Is my network information kept private?

Yes. The subnet math executes 100% in your local web browser. No IP addresses or internal subnet structures are ever sent across the network.
