DNS delegation is a crucial aspect of how the Internet directs users to the correct websites, even though most people are unaware of it. When you type in a domain like example.com, a behind-the-scenes process begins that relies on a system called the Domain Name System (DNS). One of the most important steps in that process is DNS delegation, which is a way of handing off control of part of a domain to another DNS server. In this article, we’ll break down what it is, how it works, and why it matters for website owners, businesses, and IT professionals.
What Is DNS Delegation?
DNS delegation is the process of assigning responsibility for a portion of the DNS namespace (such as a subdomain) to another DNS server. Think of it like passing the baton in a relay race, where the main DNS server passes control of a specific part of a domain to another server that can answer queries more directly.
