## What this section covers

This is the entry page for the "Airports & VPN Wiki" category, aimed at people who know
nothing about this space yet. After reading these few pages you should be able to follow
the common jargon, tell a trustworthy service from a sketchy one, and know which type of
service actually fits your situation.

The content is distilled from several usage guides and public materials the founder
provided, rewritten in neutral language. It doesn't recommend or review any specific
provider, and it doesn't include subscription links, account credentials, or any other
commercial information.

## Sub-pages

- [Glossary](./glossary) — the terms beginners get stuck on most: airport, protocol,
  rate multiplier, relay/landing, IEPL/IPLC leased lines, residential IP, DNS leaks
- [How services are categorized](./how-to-classify) — self-hosted vs. resold, line
  types, billing models, and target use cases — the common ways people slice this up
- [How to choose as a beginner](./how-to-choose) — which things are actually worth
  verifying, and which ones are easy to get misled by in marketing copy
- [Common red flags](./red-flags) — early warning signs a provider is about to
  disappear, and a few marketing claims worth taking with a grain of salt
- [Current state of the domestic "airport" market](./market-overview) — the
  industry's overall structure, the cost/acquisition logic behind extremely-low-cost
  plans, and why shutdowns are a structural norm
- [How node region relates to platform access](./region-and-access) — which
  domestic platforms restrict overseas IPs, which overseas platforms restrict
  datacenter IPs, and what the common node regions (HK/TW/JP/SG/US) are each
  typically good for

## What this deliberately does not cover

For product-focus and information-security reasons, this category will not include:
subscription links or purchase recommendations for specific providers, shared-account
content for bypassing App Store region restrictions, or step-by-step client screenshot
tutorials (these depend on specific software versions, go stale quickly, and don't
belong under "general knowledge").
