What makes the Quick DNS Lookup different?
It prints one line per record and nothing else — no header, no AUTHORITY or ADDITIONAL section, no TTL. That makes it the fastest to read when you only need the current value, and the easiest output to copy into a script or a ticket.
When should I use the DNS Query Tool instead?
When the answer looks wrong. The DNS Query Tool shows the full response — which nameservers are authoritative, what extra records came back, the response flags — which is what you need to see why, not just what.
What DNS record types should I know?
- A — IPv4 address of the domain.
- AAAA — IPv6 address.
- CNAME — alias pointing to another hostname.
- MX — mail server(s) for the domain.
- TXT — free-text records; used for SPF, DKIM, domain verification.
- NS — nameservers authoritative for the domain.
- SOA — start-of-authority; holds the primary NS and serial number.
- PTR — reverse DNS; maps an IP to a hostname.
What is TTL and why does it matter?
Time To Live (TTL) is the number of seconds resolvers are allowed to cache a Domain Name System (DNS) record. A TTL of 300 means the record may be cached for up to 5 minutes. Lower TTLs allow faster propagation of changes; higher TTLs reduce DNS query load but mean old records stick around longer after a change.
Why do I get different results from different resolvers?
Results can differ due to caching (each resolver may have cached a different version), geo-DNS (some Content Delivery Networks (CDNs) return different IPs based on the resolver's location), or propagation delays after a recent Domain Name System (DNS) change. Use the DNS Propagation tool to query many resolvers simultaneously.
