dig output and DNS zone explainer
dig transcripts and zone records explained line by line; no resolver.
Paste a dig transcript (header/status/flags, question, answer lines) or zone records (SOA/NS/A/AAAA/CNAME/MX/TXT/PTR/CAA/SRV): each RR is explained, and unsupported types are listed as unexplained instead of guessed.
Paste, drop, or type to begin. Everything stays on this device.
