AltF DomainOps reads a domain's public DNS and registration records and returns a readiness score out of 100 with a plain-language finding for each check: address records, nameserver redundancy, mail routing, SPF, DMARC, CAA, RDAP registration data and, if you supply a selector, DKIM. It queries Google Public DNS over HTTPS and the RDAP.org bootstrap service and never connects to the website itself, so it reports nothing about page content, uptime, TLS certificates or performance.
