Frequently Asked Questions
DNS (Domain Name System) lookup translates human-readable domain names like example.com into IP addresses that computers use to communicate. When you perform a DNS lookup, it queries DNS servers to retrieve various records including A (IPv4), AAAA (IPv6), MX (mail), CNAME, TXT, and NS records.
Common DNS record types include: A records (map domain to IPv4 address), AAAA records (map to IPv6), MX records (mail server), CNAME (alias to another domain), TXT records (text information, often for verification), NS records (nameservers), and SOA records (start of authority with zone information).
DNS lookups help troubleshoot website connectivity issues, verify domain configuration, check mail server settings, validate DNS propagation after changes, investigate potential phishing domains, and audit domain security settings like SPF and DKIM records.
DNS propagation typically takes 24-48 hours to complete globally, though many changes appear within minutes to a few hours. The TTL (Time To Live) value on DNS records affects how long servers cache the information before requesting fresh data.
