Frequently Asked Questions
What utility queries does the DNS Lookup handle?
It triggers queries for A (IPv4), AAAA (IPv6), MX (Mail Exchange), TXT (Text values like SPF/DKIM), CNAME (Aliases), and NS (Name Server) records.
How does WHOIS retrieve information?
Our server queries domain registrars and registries directly via the port 43 WHOIS protocol to fetch contact info, server records, creation/expiry dates, and registration statuses.
Are queries secure?
Yes, we strictly sanitize input strings using regular expressions on the backend before launching native networking commands (`dig` & `whois`) to guarantee safe execution.
