Frequently Asked Questions
What is DNS lookup?
DNS lookup queries Domain Name System servers to find records like IP addresses (A/AAAA), mail servers (MX), and other domain information.
What DNS record types can I query?
Common types: A (IPv4), AAAA (IPv6), MX (mail), CNAME (alias), TXT (text), NS (nameserver), SOA (authority), and PTR (reverse).
Why would DNS lookup fail?
Reasons include: domain doesn't exist, DNS server timeout, incorrect record type queried, or domain has no records of that type.
What is TTL in DNS records?
TTL (Time To Live) specifies how long (in seconds) a DNS record should be cached. Lower TTL means faster propagation of changes.
