DNS Terminal Tools

DNS (Domain Name System) maps names such as terminaltrove.com to IP addresses through a hierarchy of resolvers and authoritative name servers.

 

In the terminal, DNS work means querying records with dig or a friendlier client, reading A, AAAA, MX, TXT and SOA records, watching a change propagate across public resolvers, and running WHOIS lookups on a domain. Sysadmins, SREs and anyone moving a domain to a new host start here when a service is unreachable and the network itself looks healthy, ahead of the broader network diagnostics tools.

 

Below is a list of terminal tools that query and diagnose DNS.
