DNS Records Check

What are DNS records?

DNS records (Domain Name System) are a set of instructions that link domain names to IP addresses and other important parameters. They help browsers and other services find the necessary servers for loading websites, processing emails, and other internet functions.

What types of DNS records exist?

There are several types of DNS records:

A — (maps a domain to an IPv4 address)
AAAA — (maps a domain to an IPv6 address)
CNAME — (points to another domain name)
MX — (defines the mail server for a domain)
TXT — (contains text information)
NS — (specifies the name servers for a domain)

Why check DNS records?

Checking DNS records ensures your domain is correctly configured.

Frequently Asked Questions

How to find out which DNS records a domain has?

Methods for checking DNS records: nslookup – a standard tool for checking DNS records on Windows. dig – a command-line tool for working with DNS on Linux and macOS. whois – retrieves domain information, including DNS records. Online services – such as MXToolbox, Google Admin Toolbox, and DNS Checker allow you to quickly check domain records without installing additional software. These tools help determine which records are configured for your domain, including A, MX, CNAME, and others.

Why are my DNS records not updating?

DNS changes may not update immediately due to caching at various levels. To speed up DNS updates, clear your cache, use alternative DNS servers (such as Google DNS 8.8.8.8), or check the status using online tools like DNS Checker.

How to check MX record correctness?

To check the validity of MX records (Mail Exchange), use specific commands or online tools. If records are misconfigured, emails may not be delivered or may go to spam. Ensure that your domain has at least one MX record pointing to the correct mail server.
