DNS Records Checker

What is a DNS Records Checker?

A DNS Records Checker is a tool that allows you to query and verify the DNS records associated with a domain name. DNS records contain essential information about a domain, such as IP addresses, mail server details, and other data needed to direct internet traffic correctly. By using a DNS Records Checker, you can ensure that these records are correctly configured and identify any issues that might affect your website's performance and accessibility.

Types of DNS Records

Before diving into the use of a DNS Records Checker, it's helpful to understand the various types of DNS records:

1. A Record (Address Record): Maps a domain name to an IPv4 address.
2. AAAA Record (IPv6 Address Record): Maps a domain name to an IPv6 address.
3. CNAME Record (Canonical Name Record): Maps a domain name to another domain name.
4. MX Record (Mail Exchange Record): Specifies the mail servers responsible for receiving email on behalf of a domain.
5. TXT Record (Text Record): Contains text information for various purposes, such as SPF (Sender Policy Framework) for email validation.
6. NS Record (Name Server Record): Indicates which name servers are authoritative for the domain.
7. PTR Record (Pointer Record): Maps an IP address to a domain name (reverse DNS lookup).
8. SRV Record (Service Record): Specifies the location of servers for specific services.
9. SOA Record (Start of Authority Record): Contains administrative information about the domain.
