The Domain Name System (DNS) is the phonebook of the internet. It translates domain names like example.com into IP addresses. A DNS Lookup queries these records in real time.
A records point to IPv4 addresses, AAAA records to IPv6. MX records define which servers receive email. TXT records often contain SPF and DKIM entries for email authentication.
Relevant for AI visibility: Correct DNS configuration is a prerequisite for AI crawlers like GPTBot, ClaudeBot and PerplexityBot to resolve your domain at all.
A DNS Lookup queries the DNS records of a domain. You get information like IP addresses (A/AAAA), mail servers (MX), name servers (NS) or text entries (TXT).
TTL (Time to Live) indicates how long a DNS record is cached by resolvers, in seconds. A TTL of 300 means 5 minutes. Low TTL values are useful when making DNS changes.
A records contain IPv4 addresses, AAAA records contain IPv6 addresses. Modern servers often have both for optimal reachability.
TXT records contain freely definable text. Commonly used for SPF, DKIM, DMARC and domain verifications for Google, Meta and other services.
MX records (Mail Exchanger) define which servers receive email for a domain. Lower priority values are used first.
