I believe many students are concerned about the high data costs of the campus network. The university is constantly exploring ways to reduce traffic usage. Recently, I encountered a situation where my monthly free data limit was only 3 GB, which was the first time I experienced such low bandwidth on a broadband connection. To solve this issue, I discovered methods to access the internet for free using IPv6 and want to share them with you.
**Note:** These methods rely on IPv6 access. Make sure your network supports IPv6 before proceeding.
**First, how do you check if IPv6 is available?**
Go to your network settings, open the connection you're using, and check the status of IPv6. If it shows "Internet" or "Connected," then IPv6 is enabled. You can continue. If not, you may need to switch to another method or contact your IT department.
In some cases, like in dorms at Xidian University, you might need to dial into the broadband network first to get IPv6 access. After logging in, your campus network is active, so be sure to disable IPv4 to avoid using up your data. Go to your network settings, open the broadband connection, click Properties, and uncheck the IPv4 protocol. This way, your data usage won’t be counted against your campus plan.
**Now, let’s talk about some ways to access the internet without using your campus data:**
1. **Campus v6 – https://xiaoyuanv6.com/**
This is a Shadowsocks-based VPN that offers 3 GB of traffic per month. It works well for daily use, has decent speed, and even allows you to bypass regional restrictions. You’ll need to download the Shadowsocks client, which is relatively easy to set up.
2. **Immediately Six – http://MsDownload/**
This is simpler than Campus v6. You just need to download a client, register, and you’re good to go—no configuration required. However, the speed can be unstable. During off-peak hours, it's fast enough for downloading files, but during peak times, it can be slow. Still, it’s sufficient for browsing the web.
3. **Six Speed Dial – http://[link]/**
Similar to the above, but with more stable speeds. It’s recommended for gaming or streaming. However, there’s a limit of 50K per second, which is still acceptable for most tasks.
You can also directly access websites like Google or YouTube via IPv6, provided your campus network supports it. Just make sure your device is connected via IPv6, and those sites will not count against your data.
**After trying several options, I found that setting up a VPS to run a Shadowsocks server is the most effective solution.**
**How it Works:**
The idea is to use the campus network’s IPv6 connection, which doesn’t charge for data. Since few websites support IPv6, we need an intermediary—this is where the VPS comes in. Your VPS must have an IPv6 address. You connect to it via its IPv4 address, and then communicate back through IPv6. This means all traffic goes through the VPS instead of your campus network, effectively saving your data.
To make this work, you’ll need Shadowsocks. It acts as a proxy, allowing you to route your traffic through the VPS. The setup involves installing the server on the VPS and the client on your computer.
**Recommended Tools:**
1. **VPS Provider – BandwagonHost**
A popular choice due to its affordability and one-click Shadowsocks installation. It supports IPv6 and accepts Alipay, which is great for users in China. However, it only has a US node, which may cause latency issues for some users.
- Pros: Low cost, easy to use, 3 IPv6 addresses included.
- Cons: Limited node options, older versions of the client may not work perfectly on Windows 10.
2. **Shadowsocks Client**
You can download the official client from GitHub (https://github.com/shadowsocks/shadowsocks-windows/releases). Be aware that downloads from GitHub can sometimes be unreliable. Another option is to use the one-click installer from BandwagonHost, which still provides a working version, though it's slightly outdated.
**Installation Steps (for BandwagonHost):**
After purchasing a VPS, you'll need to install an OS, set up the Shadowsocks server, and configure the client. The process is straightforward, especially with their one-click tool. For DigitalOcean, the setup is similar but requires more manual configuration, which I’ll cover in a future update.
Overall, using IPv6 along with a VPS and Shadowsocks is a solid strategy to save on campus data usage. It’s a bit technical, but once set up, it works smoothly and reliably. Let me know if you’d like a step-by-step guide for any specific provider!
