shallowrs.heade/lookup · Verify this server
Look up a domain, IP address or network (AS number) on heade.rs and return its report. For a domain or IP address: where it's hosted (network, BGP prefix, RPKI, location, cloud region, CDN), registration (RDAP/WHOIS), DNS records and DNSSEC, email security (SPF, DMARC, MTA-STS, BIMI), the certificate, a security-header grade and the response headers, the website's tech stack with end-of-life and vulnerability checks, which AI crawlers it lets in and what it offers agents, and open ports from Shodan InternetDB. For an AS number: its prefixes, RPKI and ASPA, upstreams and peers, internet exchanges and registration. Data is live or mirrored within the hour; a lookup takes a few seconds.
