MX lookup finds the mail servers for a domain name. It queries the domain name's authoritative DNS server to find the records, so any changes should be visible immediately. If the domain uses a popular mail provider, this tool will also show its name.
Other record types
Besides MX 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.
