DNS records help direct internet traffic and support services such as websites, email, and domain verification.

When using DNS Lookup, you may encounter several different record types. Each record serves a specific purpose and helps internet services locate resources or verify information.

For example, A and AAAA records help connect domain names to IP addresses, MX records help direct email, TXT records can store verification and authentication information, NS records identify nameservers, and CNAME records create aliases between domain names.

While the terminology can seem technical at first, understanding a few common record types can make DNS results much easier to interpret.

A good way to think about DNS records is that each one has a specific job.

Some records help visitors find a website, others help email reach the correct destination, and others verify that services are authorized to operate on behalf of a domain.

Once you understand the role of each record type, DNS lookup results become much easier to interpret.
