DNS diagnostics in one report
Run DNS health, DNSSEC, backup-readiness, dangling CNAME and registration checks from one domain.
Individual tools
Open a focused checker when you need a narrower report or a specialized input.
DNS propagation
See what DNScale's authoritative nameservers serve right now, alongside what public recursive resolvers currently cache.
SPF validator
Validate your SPF record: check syntax, count DNS lookups, and catch common mistakes before they cause email delivery failures.
DKIM validator
Enter your domain and DKIM selector to validate the key — check algorithm, key length, and mandatory tags in seconds.
DMARC validator
Validate your DMARC policy: check enforcement level, alignment settings, reporting addresses, and subdomain coverage.
WHOIS
Look up domain registration details — registrar, expiry date, nameservers, and status codes — straight from the registry.
DNS lookup
Resolve any DNS record type directly — like dig in your browser. A, AAAA, CNAME, MX, TXT, NS, SOA and more.
DNS health
DNScale Check for delegation, SOA, nameserver diversity, DNSSEC, MX, SPF, DMARC and CAA — pass, warn, fail.
DNS backup readiness
DNScale Check for secondary DNS and multi-provider readiness: delegation, provider diversity, IPv6, reachability, SOA serials and DNSSEC.
Dangling CNAME
Find CNAME records that point at missing external services before they become domain takeover risks.
DNSSEC chain
Walk the DS → DNSKEY chain of trust from any zone up to the root. See which link is signed, which is broken, which is a plain trust gap.
