Domain lookup email addresses

A domain lookup is a process of querying a domain name system (DNS) to retrieve information about a domain name. This information can include the IP address associated with the domain, the mail exchanger (MX) records, and other DNS records.

Here are some common DNS records that can be looked up for an email address:

  1. MX Records: These records specify the mail servers responsible for accepting email messages on behalf of a domain. You can use tools like MX Toolbox or DNSstuff to look up the MX records for a domain.
  2. A Records: These records map a domain name to an IP address. You can use tools like WhatIsMyIP or DNSstuff to look up the A records for a domain.
  3. PTR Records: These records map an IP address to a domain name. You can use tools like WhatIsMyIP or DNSstuff to look up the PTR records for an IP address.
  4. SPF Records: These records help prevent spam by specifying which mail servers are authorized to send email on behalf of a domain. You can use tools like SPF Record Lookup or DNSstuff to look up the SPF records for a domain.
  5. DKIM Records: These records help verify the authenticity of email messages by specifying a digital signature. You can use tools like DKIM Record Lookup or DNSstuff to look up the DKIM records for a domain.
