Frequently Asked Questions
What is DNS lookup?
DNS lookup is the process of querying the Domain Name System (DNS) to resolve a domain name into its corresponding IP address or retrieve specific DNS configurations like MX and TXT records.
Which DNS records are supported?
This tool supports A (IPv4), AAAA (IPv6), MX (Mail server), TXT (Text verification), CNAME (Aliases), NS (Nameservers), and SOA (Start of Authority) records.
Are these DNS lookups cached?
The tool fetches live records to minimize cached information, though local DNS resolvers or intermediate nameservers may cache TTL values depending on network parameters.
