Free DNS diagnostic tools
Check DNS propagation, audit zone health, validate DNSSEC chains.
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 ā 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 ā registrar, expiry date, nameservers, and status codes ā straight from the registry.
DNS lookup
Resolve any DNS record type directly ā like dig in your browser. A, AAAA, CNAME, MX, TXT, NS, SOA and more.
Zone health
One click, one report: delegation, SOA, nameserver diversity, DNSSEC, MX, SPF, DMARC and CAA ā pass, warn, fail.
DNSSEC chain
Walk the DS ā 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.
