# Look Up DNS Records

DNS records are the foundation of how the internet routes traffic, delivers email, and verifies domain ownership. When something breaks -- a website goes down, emails bounce, or a verification fails -- the first step is checking DNS records to see what is actually configured.

The lookup_dns skill queries DNS records for any domain and returns the full set of configured records. See A records pointing to your servers, MX records routing your email, TXT records for verification and SPF, and everything else. No need to remember dig syntax or switch between lookup tools.
