About the DNS Lookup
DNS Lookup resolves a domain's core records so you can see exactly what the Domain Name System returns for it. Query A and AAAA records for IPv4 and IPv6 addresses, MX for mail routing, TXT for verification and policy strings, NS for delegation, CNAME for aliases, and SOA for zone authority. It is the fastest way to confirm how a hostname is configured and to debug resolution problems before they reach production.
How to use
- Enter the domain name you want to inspect (for example, example.com).
- Select the record type you need, such as A, AAAA, MX, TXT, NS, CNAME, or SOA.
- Run the lookup and review the returned records and their TTL values.
- Repeat with other record types to build a full picture of the zone.
Frequently asked questions
- What is the difference between an A and an AAAA record?
- An A record maps a hostname to an IPv4 address, while an AAAA record maps it to an IPv6 address. A domain can publish both.
- Why does a domain return multiple records of the same type?
- Operators often publish several A records or MX records for redundancy and load distribution. Resolvers and mail servers choose among them based on round-robin or priority.
- What does the TTL value mean?
- TTL (time to live) is how long, in seconds, a resolver may cache the record before querying again. Lower TTLs propagate changes faster but increase query volume.
