Look Up DNS Records

Query DNS records for any domain to inspect A, AAAA, MX, CNAME, TXT, and NS configurations.

DNS Domain

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.
