This concept evolved into the DNS as we know it in the early 1980s, with the release of foundational specifications documented in Request for Comments (RFCs). DNS is organized into a hierarchical structure akin to a tree, where the root zone branches into various domains and sub-domains, each containing resource records that provide essential information about network resources.
