WHOIS Lookup Registration data for domains, IPs and ASNsA DNS lookup queries the Domain Name System to reveal how a domain is configured: the IP addresses it points to (A/AAAA), the servers that handle its email (MX), its authoritative name servers (NS) and the text records (TXT) used for verification, SPF and more. IPeek queries every supported record type and caches the answer for 15 minutes.
A DNS lookup translates a domain name into the records that describe it — IP addresses, mail servers, name servers and text records — by querying the Domain Name System.
IPeek resolves A, AAAA, MX, NS, TXT, CNAME, SOA, CAA and SRV records, plus reverse DNS (PTR) when you enter an IP address.
DNS records are cached for a time-to-live (TTL) period and can vary by resolver and geography during propagation.
