DNS lookup
Look up A, AAAA, CNAME, MX, TXT, NS, SOA and CAA records for a domain across two independent resolvers, and see straight away whether they agree.
Queries Cloudflare and Google resolvers independently. Address records are shown from both but not compared — any CDN hands out different IPs by design. NS, MX, TXT and CAA records are cross-checked, and a disagreement there means a change is still propagating.
Monitor this automatically
Get an email the moment a DNS record changes. Catches an expired domain silently repointing, a hijacked subdomain, or a teammate editing production DNS without telling anyone.
Why two resolvers
A single lookup tells you what one resolver has cached, not what the world sees. Querying two independent resolvers catches the common case where a change has landed at one and not the other — which is usually the difference between “it’s broken” and “wait five minutes”.
