Look up DNS records, mail servers, nameservers, and compare answers from public DNS resolvers.
DNS RESULTS
Results
DNS records
Results from Google Public DNS. Values and TTLs can change over time.
DNS resolver comparison
Compare cached responses from Google Public DNS and Cloudflare 1.1.1.1. This is not a worldwide propagation test.
What does this tool check?
MX / TXT
Mail routing and text entries, including SPF, domain verification and DMARC.
NS / SOA
Nameservers and DNS authority details for a zone.
Resolver comparison
Different public resolvers may temporarily return different cached answers. Matching results do not prove global propagation.
Your browser sends the queried hostname to Google Public DNS and Cloudflare DNS over HTTPS. W1SYS does not need to store your searches.
