Keep names and addresses separate
A name is a durable label. An address is one answer about where to try a connection. Treating them as separate observations makes a problem easier to describe.
Names, paths & everyday questions
Network Fieldbook
Seven practical readings on clear observations, readable references and useful next steps.
This collection brings a few related questions into one place. Each short reading introduces a concrete distinction, gives a familiar example and leaves a modest next step. Use the full index to choose an entry or follow the links between neighbouring notes.

Follow one question at a time
What a verified connection tells you
A certificate check connects a secure session to the requested name. The page returned inside that session still deserves its own review.
Delay and throughput answer different questions
A quick first reply and a fast transfer describe different parts of an experience. A single number cannot stand in for both.
Read from the boundary you can see
Start with names if an address seems unexpected, or identity if a secure connection reports a warning. For a page that loads slowly, the notes on latency and request budgets offer two different ways to look at time.
The readings are intentionally small. None depends on a particular product, network operator or account. Keep a useful explanation, try one modest check, and return to the index when the question changes.
