What A records do
A records map a domain name to an IPv4 address used by browsers and clients to reach your server.
Why TTL matters
TTL controls DNS cache lifetime. Lower TTL speeds propagation, while higher TTL reduces query load.
Common troubleshooting
Use A lookups to verify cutovers, rollback targets, and whether resolvers are seeing updated IPs.
Resolver source

Look up IPv4 A records for any domain with one DNS query and export structured output for troubleshooting and documentation.
Only the domain you enter is sent to Google Public DNS for one A query. No files, credentials, or private content are uploaded.
