DNS and TXT/CNAME checker

Check the records for a domain: A, AAAA, CNAME, MX, TXT, and the SPF and DMARC records. Each lookup is sent to two public resolvers (Google and Cloudflare) so you can see whether they agree yet. This is not a worldwide probe; it shows what two public resolvers return right now.

Domain

Domain (for example example.com) DKIM selector (optional, for example google or selector1)

Checks

Records can take time to spread after a change (the TTL on the old record sets how long). If the two resolvers disagree, wait and check again. Nothing is stored. For more email and domain tools, see GPS Tools.
