Global DNS Checker
Check DNS propagation by comparing A, AAAA, CNAME, MX, NS and TXT records across global resolvers. Free online DNS lookup with DNSChecked.
Run a DNS check
Enter the domain name or IP, and click the button to check DNS resolution.
F2 focuses the domain field; Enter checks.
Multiple record types (optional)
Expected answers (optional)
One record per line. Exact compares the entire answer set; order and duplicates do not matter.

Compare DNS answers across regions
Compare each resolver's answers with your expected records. Differences can reflect cached records, recent changes or resolver behavior. A successful lookup alone does not establish that every network has updated.
Understanding DNS propagation
How to check DNS propagation
- Enter the Domain or Hostname
First, provide the website domain name you wish to check for DNS resolution propagation.
- Select DNS Record Type
Choose the DNS record type you want to check for propagation status.
- Check
How to interpret the results
- A successful lookup means the resolver returned an answer. Compare its records with your expected values.
- NXDOMAIN, no records, a timeout and a query failure are different outcomes. Read the details for each resolver.
DNS record types you can query
The record types include:
- A Record: The most basic type of record, also known as an address record, provides an IPv4 address for a domain or subdomain. This record points a domain name to an IP address.
- AAAA Record: Maps a hostname to a 128-bit IPv6 address. For a long time, 32-bit IPv4 addresses have been used to identify computers on the internet. However, due to the shortage of IPv4, IPv6 was created. The four 'A's (AAAA) are a mnemonic, indicating that IPv6 is four times larger than IPv4.
- CNAME Record: Also known as the canonical name record, it creates an alias for a domain name. Alias domains or subdomains get all the DNS records of the original domain, typically used to associate subdomains with an existing main domain.
- MX Record: Also known as the mail exchange record, it informs which mail exchange servers are responsible for routing emails to the correct destination or mail server.
- NS Record: Also known as the name server record, points to the name server that has the authority to manage and publish DNS records for the domain. These DNS servers are authoritative in handling any queries related to that domain.
- PTR Record: Also known as the pointer record, points an IPv4 or IPv6 address to the hostname of its computer. It provides reverse DNS records or rDNS records by pointing an IP address to the server's hostname.
- SRV Record: Also known as the service record, indicates specific services and port numbers running in a domain. Internet protocols such as Extensible Messaging and Presence Protocol (XMPP) and Session Initiation Protocol (SIP) often require SRV records.
- SOA Record: Also known as the Start of Authority record, provides basic information about the domain, such as identifying the primary node of the authoritative name server for the domain, the domain administrator's email, the serial number of the DNS zone, etc.
- TXT Record: Allows website administrators to insert arbitrary text in the DNS record.
- CAA Record: Also known as the Certificate Authority Authorization record, reflects public policies about issuing digital certificates for the domain. If your domain doesn't have a CAA record, any certificate authority can issue an SSL certificate. However, with this record, you can restrict which CA is authorized to issue digital credentials for your domain.
- DS Record: Also known as the Delegation Signer record, consists of a unique character of a public key and its associated metadata such as the key tag, algorithm, digest type, and an encrypted hash value known as a digest.
- DNSKEY Record: Also known as the DNS Key record, contains public signing keys, like the Zone Signing Key (ZSK) and the Key Signing Key (KSK). DS and DNSKEY records validate the authenticity of DNS records returned by DNS servers.
