Frequently asked questions

What does a DNS lookup show?
A DNS lookup returns records like A/AAAA (IP addresses), MX (mail servers), TXT (verification), NS (name servers), and CNAME (aliases).
Why do DNS results vary by location?
Some domains use geo-routing and CDNs, so DNS answers can differ depending on location, resolver, and cache state.
What is the TTL in DNS results?
TTL is the time a resolver should cache a record before refreshing it.
