🎓Learn: DNS records
A
IPv4 address of the host.
AAAA
IPv6 address of the host.
MX
Mail servers that accept email for the domain, with priority.
TXT
Free-form text — SPF, domain verification, DKIM, and more.
NS
Authoritative name servers for the zone.
CNAME
Alias pointing this name at another canonical name.
SOA
Start of Authority — zone serial, primary NS, and refresh timers.
CAA
Which certificate authorities may issue certs for the domain.
What is a TTL?▾
Time To Live — how many seconds resolvers may cache a record before re-querying. Low TTLs make changes propagate fast but add lookup load; high TTLs are efficient but slow to update. Drop the TTL a day before a planned change.
Why do different resolvers return different answers?▾
Geo-based (GeoDNS/anycast) records intentionally hand out different IPs by location, and caches expire at different times. Compare resolvers with the DNS Propagation tool to see whether a change has rolled out everywhere.
How does this tool query DNS from the browser?▾
It doesn’t query directly — the request goes to our server, which asks a public resolver over DNS-over-HTTPS (DoH) and returns clean JSON. That keeps the page’s security policy tight and avoids browser CORS limits.
