What Is a DNS Record?
DNS records connect domain names to IP addresses, mail servers, and other internet service information. A and AAAA store addresses, MX identifies mail servers, NS identifies name servers, and TXT can hold policy and verification data.
Choosing the record to inspect
Use A or AAAA for web-server addresses, MX for mail routing, NS for authoritative name servers, CNAME for aliases, and TXT for verification or email policies. CAA can restrict which certificate authorities may issue certificates for the domain.
Interpreting TTL and propagation
TTL is a cache lifetime, not a promise that every resolver updates at the same moment. After a DNS change, old answers can remain visible until intermediate caches expire; an empty result may also simply mean that the selected record type is not configured.
Frequently Asked Questions
Why does the result say no records were found?
A domain can exist without having the selected record type. Select another record type and try again.
What is TTL?
TTL is the number of seconds a DNS response may remain in a cache.
Why is a DNS change not visible yet?
A resolver or network cache may continue showing the previous value until its TTL expires.
