DNS Lookup

A DNS lookup queries the Domain Name System to find the IP address and other records associated with a domain name. When you type a website address in your browser, DNS translates that human-readable name into an IP address that computers use to route traffic.

A records map a domain to an IPv4 address. AAAA records map to IPv6. MX records specify mail servers. NS records identify authoritative nameservers. TXT records hold text data like SPF and DKIM for email authentication. CNAME records create domain aliases. SOA records contain zone authority information.

DNS changes typically propagate within 1-48 hours, depending on the TTL (Time To Live) value set on the records. Records with low TTL values (300 seconds) propagate faster. You can use this tool to check if your DNS changes have taken effect by querying different record types.
