DNS Lookup
Look up any DNS record type for any domain: A, AAAA, MX, CNAME, TXT, NS, SOA, and PTR. Supports multiple DNS resolvers (Google, Cloudflare, custom) for comparison.
Uses Google Public DNS (dns.google) via DoH (DNS over HTTPS).
Frequently Asked Questions
What do the different DNS record types mean?
A: IPv4 address. AAAA: IPv6 address. CNAME: Alias to another domain. MX: Mail server. TXT: Text data (SPF, DKIM, domain verification). NS: Name servers. SOA: Start of authority (primary NS info). TTL is time-to-live in seconds — how long to cache the record.
Why do DNS changes take time to propagate?
DNS records are cached by resolvers worldwide based on the TTL value. A TTL of 3600 means records are cached for 1 hour. To speed up propagation before a DNS change, reduce TTL to 300 (5 min) 24-48 hours in advance.
