DNS Lookup: Global DNS Propagation Checker

A DNS lookup resolves a domain name to the records published by its authoritative nameservers — most commonly an IP address, but also mail routing (MX), text verification records (TXT/SPF/DKIM), or name server delegation (NS). This tool runs the query from nodes distributed across different countries and ISPs, so you can see whether your DNS is resolving consistently worldwide or returning different results by region.

Supported DNS Record Types

Select a specific record type below to perform a dedicated global propagation test.

Record Type Description
A / AAAA Tests both IPv4 (A) and IPv6 (AAAA) resolution simultaneously.
A Points a domain name to an IPv4 address. Most common for basic website traffic.
AAAA Points a domain name to an IPv6 address, essential for modern network compatibility.
CNAME An "Alias" record that points one domain to another domain (e.g., pointing a subdomain to a root domain).
MX Mail Exchange record; directs email traffic to the specific servers responsible for receiving messages.
NS Indicates which Name Servers are authoritative for the domain, telling the internet where to find the domain's settings.
TXT Allows admins to insert text into the DNS. Primarily used for SPF, DKIM, and DMARC to prevent email spoofing.
PTR Pointer record used for Reverse DNS (rDNS) lookups, mapping an IP address back to a hostname.
SOA Start of Authority record containing core administrative information about the zone.
SPF Sender Policy Framework record used to specify authorized mail servers (deprecated, use TXT).
SRV Service record specifying the hostname and port number for specific internet services.
CAA Certification Authority Authorization record dictating which authorities can issue SSL certs.
DNSKEY Contains the public signing key for DNSSEC to verify the authenticity of DNS records.
EDNS Extension mechanisms for DNS, providing additional features and larger UDP packet sizes.
AXFR Zone transfer request used to replicate DNS records across primary and secondary name servers.
MAILB Mailbox-related record (historical) for specifying a mailbox.
MAILA Mailbox-related record (historical) for mail routing.
MD Mail Destination record (obsolete, replaced by MX).
MF Mail Forwarder record (obsolete, replaced by MX).
MB Mailbox Domain name record (experimental).
MG Mail Group member record (experimental).
MR Mail Rename domain name record (experimental).
NULL Null record used for testing and experimental extensions.
WKS Well Known Service description record (obsolete).
MINFO Mailbox or mail list information record.
