Web Analyzer

Six things for one domain: the server's IP address with its location and ISP, the network (AS number) that announces that IP, DNS records plus SPF, DKIM, DMARC, and DNSSEC checks, whois data and the domain's expiry, the SSL certificate and TLS versions, and its status on blacklists (DNSBLs). Each card is a compact version of its standalone tool; "See details" opens the full result.

Each card loads on its own. DNS and the server location finish within a second, while whois has to ask the registry and the blacklist check queries dozens of lists, so they can take several seconds. If one card fails to load, the others are unaffected.

The summary adds up the checks of all cards. Fail means something needs fixing, such as an expired certificate, an IP on a blacklist, or a domain with no IP address. Warning means it works but is not ideal, like SPF without -all or a domain expiring within 30 days. The network card is informational only, so it is not counted.

Yes. For an IP, the DNS card shows its reverse DNS, whois shows the owner of the IP block, and the blacklist check queries that IP directly. The SSL card still tries port 443 on it.

Yes. curl 'ipku.in/en/tools/web-analyzer?q=example.com' runs every check at once and prints plain text, and /api/analyze/example.com returns JSON. Since it waits for the slowest check, it can take up to half a minute.
