Welcome to DNSDetangler

DNSDetangler is a tool that can help you to break down your domain into easy to understand pieces! Enter a domain name in a form like: "stackoverflow.com" to try it out.

The DNS provider is the company that hosts your DNS records. This is where you will go to make changes to your DNS records. The DNS provider is determined by the name servers that are listed for your domain.

The MX record is used by email servers to determine where to send email for your domain. This is how users are able to contact you. The priority is used to determine which server to send email to first. The target is the domain name of the email server.

SPF records allow recipients to identify 'spoofers' that may be sending messages that appear to be from you. An SPF record is a TXT record that is part of your domain's DNS zone file. The TXT record specifies a list of authorized host names/IP addresses that are authorized to send email for your domain.

DMARC, which stands for “Domain-based Message Authentication, Reporting & Conformance”, is an email authentication, policy, and reporting protocol. DMARC is a way for you to discover which services (or rogue entities) are sending emails on your behalf… and then offers a way to tell recipients they should reject the ones that don't meet your SPF/DKIM criteria.

An A record (aka Address Record) maps a domain name to the IP address of the computer hosting a website. In most cases, this will point to your primary website

TXT records are used to store any text-based information that can be grabbed when necessary. The most common uses for a TXT record are to prove domain ownership, DKIM verification, and email sender policies, such as SPF records and DMARC policies.
