DNS propagation check. Check whether a DNS change has propagated: the same record queried at five public resolvers (Cloudflare, Google, AdGuard, AliDNS and DNSPod), each resolver's answers and TTLs, whether they all agree, and the majority answer. Record types A, AAAA, CNAME, MX, NS, TXT, CAA. Use to see where an old value is still cached after changing a record, moving hosting or setting up email; for one lookup use dns_lookup.
