A lookup finds the IPv4 addresses for a domain name. It queries the domain name's authoritative DNS server to find the records, so any changes should be visible immediately.
Other record types
Besides A records, there are other types of DNS records. A, AAAA, CNAME, NS, TXT, MX and SOA are the most often used. Use DNS lookup to find these records for a domain name. Click any of the record types below to find DNS records for that specific record type.
