Free DNS Lookup Tool
Check A, AAAA, MX, NS, CNAME, TXT, SPF and DMARC records for your domain.
DNS Lookup
Check your domain's DNS records
DNS records tell the internet where your domain is hosted, where email should be delivered and how other services connect to your domain. Use the free DNS lookup tool above to check the DNS configuration of any domain.
A Record
An A record points a domain name to an IPv4 address. It tells browsers which server should receive requests when someone visits your domain.
Commonly used for website hosting.
AAAA Record
An AAAA record points a domain name to an IPv6 address. It performs a similar function to an A record but uses the newer IPv6 addressing system.
Used for websites and services supporting IPv6.
MX Record
MX records specify which mail servers are responsible for receiving email sent to your domain. Incorrect MX records can prevent email from being delivered.
Important when setting up or troubleshooting business email.
NS Record
NS records identify the authoritative nameservers for your domain. These servers contain the DNS configuration that controls how your domain works.
Useful when checking where your DNS is managed.
CNAME Record
A CNAME record points one domain or subdomain to another hostname instead of directly pointing to an IP address. It is commonly used for services hosted by another provider.
Common for subdomains and third-party services.
TXT Record
TXT records allow domain owners to publish text information in DNS. They are commonly used for domain verification, email authentication and security policies.
Often used by Google, Microsoft and other online services.
SPF Record
An SPF record identifies which mail servers are authorised to send email on behalf of your domain. It can help reduce email spoofing and improve email authentication.
Usually published as a TXT record.
DMARC Record
DMARC tells receiving mail servers how to handle messages that fail email authentication checks. It can also provide reporting about email claiming to come from your domain.
Used to strengthen domain and email security.
SOA Record
The SOA, or Start of Authority, record contains important information about a domain's DNS zone, including the primary nameserver and DNS zone serial number.
Useful for understanding DNS zone configuration.
Reverse DNS Hostname
A reverse DNS hostname maps an IP address back to a hostname. It can help identify the server or network associated with the IP address used by your domain.
Useful for identifying the hosting server or network provider.
Why check your DNS records?
DNS problems can affect websites, email and other services connected to your domain. Checking your DNS records can help identify where your website is pointing, which servers handle your email and whether important DNS records are configured.
A DNS lookup is particularly useful after changing web hosting, moving your domain to a different DNS provider, setting up business email or connecting a domain to a third-party service.
