DNS names are resolved along a hierarchy. This lesson keeps that path structural and explicitly defers caching, retries, and transport behavior.

Why delegation is structural
Resolution follows a hierarchy before it reaches the answer record. This diagram keeps only the structural path parsed from the name bytes.
.→com→example→www
Root, TLD, authoritative name
The simplified path starts at the root dot, then com, then example, then the requested host. Those labels are the same parsed QNAME labels used earlier.
root→TLD→authoritative→host
The path ends in data
For this example, the final A answer carries 93.184.216.34.
0x5db8d822↔93.184.216.34
What is not shown
Real resolution may use caches, several servers, retries, and different transports — and a recursive resolver walks this path on the client's behalf. Whether resolution is recursive or iterative is not modeled here; this structural tree only names the simplified path.

Summary
Delegation is a hierarchy from the root toward the name, followed here by one A answer. Message structure and exact bytes only; resolution timing, caching, and UDP/TCP transport are not modeled here.
