Quick answers to common questions
A record: maps domain to IPv4 address. AAAA: maps to IPv6. CNAME: canonical name alias (points one domain to another). MX: mail exchange (which servers handle email). TXT: text records (used for SPF, DKIM, domain verification). NS: nameservers (authoritative DNS for the domain). SOA: start of authority (zone metadata). PTR: reverse DNS (IP to domain name).
DNS propagation depends on TTL (Time to Live) — the number of seconds resolvers cache a record. A TTL of 3600 means resolvers cache for 1 hour before re-querying. Full global propagation after a DNS change typically takes 24-48 hours, though most locations see changes within 1-4 hours. Lower TTL before planned changes reduces propagation time.
DoH encrypts DNS queries by sending them over HTTPS instead of plain UDP. This prevents ISPs and network observers from seeing which domains you look up. Major providers: Cloudflare (1.1.1.1), Google (8.8.8.8), and NextDNS offer DoH. This tool uses Cloudflare DoH first, with Google DNS as a fallback.
