DNS Lookup
Query A, AAAA, CNAME, NS, TXT, SOA records
DNS Lookup queries the Domain Name System to retrieve various record types for any domain. DNS is the internet's phonebook — it translates human-readable names like 'google.com' into IP addresses computers understand. Different record types serve different purposes.
⚙ How it works
Record types: A = IPv4 address mapping | AAAA = IPv6 address | CNAME = canonical alias (one domain points to another) | NS = authoritative nameservers for the domain | TXT = arbitrary text, commonly SPF email authentication | SOA = Start of Authority, zone metadata + primary nameserver | CAA = Certificate Authority Authorization, controls which CAs can issue SSL certs.
📊 Interpreting Results
Fast DNS response (<50ms) = good. Multiple A records = load balancing or CDN. CNAME chains should be short (1–2 hops). No NS records = misconfigured zone. TXT records with 'v=spf1' = SPF email policy configured.
