Network Calculator - Calculate subnet details for IPv4 and IPv6 addresses.
Enter an IP address with a prefix length to see the network, broadcast, host range, and binary representations. Use the split option to divide a network into smaller subnets. For supernetting, simply lower the prefix length until your supernet is the desired size.

Speed Test - Measure your connection speed to this server.
Tests download and upload throughput for up to 10 seconds or 500 MB each. Shows peak transfer rate. Results depend on browser, network conditions, and server load. For best accuracy, close other tabs and avoid concurrent network activity. Currently capped at 1 Gbps.
