Network

Q: Does the subnet calculator support IPv6?

Yes. It covers IPv4 and IPv6, including useful variations for recurring scenarios such as IPv6 and /24 CIDR.

Q: Do ports and protocols help with firewalling and troubleshooting?

Yes. Understanding ports such as 22, 80 and 443 helps when reading logs, reviewing rules and avoiding unnecessary exposure.

Network tools for operations, support and troubleshooting

The network category gathers classic infrastructure and support tasks: my IP, IP locator, subnet calculator, port reference and MAC vendor lookup.

These pages aim to answer quickly without dropping context. Beyond the main result, each tool adds enough technical explanation to help in real environments.
