Frequently Asked Questions
What is a DNS lookup?
A DNS lookup queries the Domain Name System to retrieve DNS records associated with a domain name. DNS records contain information about a domain such as which server it points to (A record), which servers handle its email (MX record), and domain ownership verification strings (TXT record).
What is an A record?
An A record (Address record) maps a domain name to an IPv4 address. For example, example.com might have an A record pointing to 93.184.216.34. This is the most common DNS record type and tells browsers which server to connect to when visiting a website.
What is an MX record?
An MX record (Mail Exchange record) specifies the mail servers responsible for receiving email for a domain. When someone sends an email to user@example.com, the sending server looks up the MX record to know where to deliver the message.
What is a TXT record used for?
TXT records store text-based information for a domain. Common uses include domain ownership verification (for Google Search Console, etc.), SPF records (to prevent email spoofing), DKIM keys (email authentication) and DMARC policies.
Why does my CNAME lookup show no results?
CNAME records can only exist on subdomains (e.g. www.example.com), not on root/apex domains (e.g. example.com). If you are looking up a root domain, try an A record instead. Most root domains use A records, not CNAME records.
Why does my AAAA lookup show no results?
AAAA records only exist if the domain has IPv6 configured. Many websites still only use IPv4 (A records). If no AAAA records are found, the domain simply does not have IPv6 enabled — this is not an error.
