Question 2

How to query DNS records for a domain?

Accepted Answer

Enter a domain in this tool, select the record type to query (A/CNAME/MX/NS/TXT), and click lookup. The tool uses Google Public DNS API (dns.google) to return authoritative resolution results. No software installation needed.

Question 3

What is TTL in DNS query results?

Accepted Answer

TTL (Time To Live) is the cache time for DNS records, measured in seconds. It indicates how long DNS resolvers Visual cache the record. Shorter TTL means faster record updates but more frequent queries; longer TTL means better cache efficiency but slower change propagation.
