About This Subnet Calculator
This advanced subnet calculator supports both IPv4 and IPv6 networking. Use it to calculate network addresses, broadcast addresses, and valid host ranges from a CIDR notation input. The VLSM splitter helps you divide a larger network into equal-sized subnets, while the supernet tool finds the smallest enclosing network for a list of CIDRs. All calculations run entirely in your browser — no data is sent to any server.
How to Use
- IPv4/IPv6 Calculator: Enter a CIDR (e.g.
192.168.1.0/24) to see full network details. - IP Validator: Check if a single IP address belongs to a given subnet.
- Bulk Validator: Paste a list of IPs to validate them all against one subnet at once.
- VLSM Splitter: Split any CIDR into N equal subnets and see each subnet's full details.
- Supernet: Enter multiple CIDRs to find the smallest single network that contains all of them.
- IP Info: Analyze any IP address — class, type, binary, hex, and decimal representations.
