dnsHow to use it
Enter a domain such as example.com or a subdomain such as blog.example.com, choose a record type and press Rechercher. “All common types” checks A, AAAA, CNAME, MX, TXT, NS, SOA and CAA together.
Which resolver should I pick?
Cloudflare (1.1.1.1), Google (8.8.8.8) and Quad9 (9.9.9.9) are large public resolvers. If you have just changed a record and they disagree, one of them is still serving a cached answer. The propagation checker compares 16 resolvers side by side.
