Frequently Asked Questions
What is a DNS lookup?
A DNS lookup queries the Domain Name System to retrieve records like IP addresses (A/AAAA), mail servers (MX), nameservers (NS), and text config (TXT). It translates domain names into machine-readable addresses.
What are the different DNS record types?
A = IPv4, AAAA = IPv6, MX = mail servers, NS = nameservers, TXT = text data, CNAME = aliases, SOA = zone authority, CAA = SSL certificate control, PTR = reverse DNS.
What is TTL in DNS records?
TTL (Time To Live) is how long a DNS record is cached. Lower TTL = faster propagation but more queries. Higher TTL = less load but slower updates. Common range: 300-86400 seconds.
Why are DNS records important for security?
DNS records reveal your infrastructure. Misconfigured DNS can lead to email spoofing (missing SPF/DKIM/DMARC), unauthorized SSL certs (missing CAA), subdomain takeover, and info disclosure.
Is this tool free?
Yes, completely free with no sign-up. 3 lookups per day. For unlimited DNS lookups and continuous monitoring, check our ASM platform.
