VPN Guides & Explainers
Practical, no-hype reading for people comparing VPN services: how to check what your connection exposes, which features decide whether a service holds up on filtered networks, and how the well-known brands actually work.
- 3 in-depth guides
- Tools you can run yourself
- Updated as features change
Guides
What Is My IP
Look up the address websites actually see, see its type, city-level location and network operator, and use the before/after comparison to confirm your VPN is really on.
5 Essential Features to Look for in a 中国vpn
A buying guide built around the five things that decide whether a service survives a filtered, high-latency path: speed and stability, security, usability on Mac and Windows, support, and multi-device coverage.
What is Express VPN?
An independent explainer of the best-known paid VPN brand: what it does, what people use it for, how the app works — and why cracked installers and shared accounts are a bad idea.
Run the checks yourself
Each guide links to something you can test on your own connection before you pay for anything:
- IP lookup — confirm the exit address changes when you connect.
- IP 查询（中文） — exit IP plus the address China-based services see.
- DNS leak guide（中文） — check whether name resolution stays inside the tunnel.
- DNS pollution guide（中文） — what to do when the lookup itself comes back tampered with.
- Download guide（中文） — verified installers for every platform.
Where to start
New to all of this? The three guides can be read in any order, but this sequence works best:
- Check your baseline: run the IP lookup first, so you know what your current connection reveals before you change anything.
- Learn what to compare: read the China VPN buying checklist — its five criteria apply to every provider, not just one market.
- Understand the big names: the Express VPN explainer covers how mainstream paid apps work day to day, including the mistakes to avoid.
Questions readers ask
Who writes these guides?
They are maintained by the Stelink VPN team as practical explainers: the goal is to help you evaluate any service, so the checklists and tests work regardless of which provider you pick. Details are checked against vendor documentation and updated when it changes.
Do I need a VPN to use these guides?
No. Every check runs fine on a normal connection — the point is to record a baseline first, then compare it with your VPN switched on.
Which guide should I read first?
If you are troubleshooting a connection, start with the IP lookup guide. If you are still comparing services, the China VPN buying checklist is the most useful starting point.
Are the Chinese-language pages different?
Some tools are published in Chinese for regional readers; where relevant, the English guides link to them, and both versions cover the same checks.
