Compare DNS resolver answers

Compare records returned by several public recursive DNS resolvers for the same domain.

DNS Lookup Tool

Enter a domain name and choose a record type to inspect its publicly visible DNS answer.

DNS Trace Tool

Follow DNS delegation from root name servers toward the authoritative servers for a domain.

Reverse DNS Lookup

Look up the reverse DNS (PTR) record published for an IPv4 or IPv6 address.

DNSSEC Checker

Inspect public DS and DNSKEY records associated with a domain.

DNS Propagation Checker

Compare records returned by several public recursive DNS resolvers for the same domain.

SSL Certificate Checker

Inspect the certificate presented by a public HTTPS host on port 443.

HTTP Headers Checker

Inspect response headers returned by a website over HTTPS.

SPF, DKIM & DMARC Checker

Check published TXT, MX and DMARC records, and optionally inspect a DKIM selector.

DNS Zone Health Checker

Get a snapshot of common DNS records relevant to zone health and delegation.

Online Traceroute Tool

Inspect network hops toward a public domain or IP address from CloudBalkan infrastructure.

Online Ping Tool

Send a limited ICMP echo test to a public domain or IP address.

How this check works

Compare records returned by several public recursive DNS resolvers for the same domain.

What to keep in mind

Different answers do not necessarily mean propagation is incomplete: CDN geo-routing and resolver caching also affect results.

Diagnostics originate from CloudBalkan infrastructure. Propagation comparisons show selected recursive resolvers, not a worldwide propagation guarantee. The DNSSEC and zone checks are snapshots rather than exhaustive audits. Ping and traceroute are subject to remote ICMP filtering. Rate limits apply.
