The internet half of Mutqan Tools: diagnostics for the network, the DNS, the website and the connection you are on, in five areas. Measure your speed and see your public address, query DNS records and registration data, inspect a site's certificate, redirects, headers and crawler files, check links, addresses and your own browser for security and privacy problems, and handle the everyday utilities — short links, QR codes, query strings, email headers and endpoint checks.
Every result is a real measurement with a named source: the Mutqan edge server, a public DNS resolver, a registry's RDAP service, a certificate transparency log, a worldwide probe network, or your own browser. Calculators and generators run locally; network checks are relayed through the Mutqan server within strict limits, store nothing, and are built for diagnosing systems you are allowed to test.
