About the DNS Lookup
DNS is the address book of the internet, and a domain's records do far more than point it at a website. This tool queries the main record types at once and lays them out with their TTLs: A and AAAA (the IP addresses), MX (mail servers), NS (name servers), TXT (verification, SPF and other text records), CNAME (aliases) and SOA (the zone's master record).
Each type answers a different question. MX records tell you who handles the domain's email; TXT records hold SPF, DKIM and DMARC lines and the verification strings services ask you to add; NS records show which provider runs the DNS. When email is not arriving, a new subdomain is not resolving, or a domain-verification step keeps failing, the answer is almost always visible here.
TTL (time to live) tells you how long each record is cached, which is why DNS changes are not instant — you often have to wait out the old TTL. For the addresses on their own, the domain to IP tool is quicker; to then inspect the server's response, use the HTTP header checker.
Frequently asked questions
Which DNS records does this show?
A, AAAA, MX, NS, TXT, CNAME and SOA — the record types that cover hosting, email, name servers, aliases and verification.
How do I check my email (MX) records?
Enter your domain and read the MX rows. They list the mail servers, each with a priority number; the lowest priority is tried first.
Where are SPF, DKIM and DMARC?
They live in TXT records, so look under TXT. SPF starts with v=spf1, and DMARC is on a _dmarc subdomain rather than the root domain.
What is TTL?
Time to live, in seconds — how long resolvers cache the record. A change only fully takes effect once the old TTL has expired everywhere.
Why do I see no records for a subdomain?
It may simply have none of the queried types, or it may use a CNAME pointing elsewhere. Check the parent domain and the CNAME rows.
