**Even Campus Network**
The campus network is a broadband, multimedia, and integrated information service system designed to support teaching, research, and administrative functions for both faculty and students. First and foremost, it should create an advanced digital learning environment that enhances the quality of education. This means the network needs to be high-speed, interactive, and tailored for academic use. Features such as a multimedia teaching platform, smart classrooms, teacher preparation systems, electronic libraries, and online exam databases can all be seamlessly integrated into this network. If the school has multiple departments or disciplines, separate local area networks (LANs) can be created and connected via wired or wireless methods to ensure smooth communication across different areas.
In addition, the campus network must also serve administrative purposes, supporting tasks like student registration, course management, and resource allocation. It should provide a secure, efficient, and scalable infrastructure that meets the growing demands of modern education.
**IPv6**
IPv6 is the next-generation Internet Protocol designed to replace IPv4, which has been in use for decades. The current version, IPv4, uses 32-bit addresses, limiting the total number of available IP addresses to about 4.3 billion. As the number of internet-connected devices continues to grow rapidly, IPv4 addresses have become increasingly scarce. This limitation has led to the development of IPv6, which uses a 128-bit address format, offering an almost unlimited number of unique IP addresses.
Beyond just addressing space, IPv6 brings improvements in security, mobility, and quality of service. It supports more efficient data routing, better network performance, and enhanced privacy features. Although IPv6 is not yet widely commercialized, it is being actively deployed in major universities and research institutions around the world.
**Why is IPv6 free of flow?**
Many universities implement a billing system that only tracks traffic based on IPv4. By using IPv6, users can bypass this metering system. When a user connects via IPv6, their communication with the server happens through IPv6, while the server itself accesses the IPv4 network to retrieve content for the user. This allows for unrestricted access without being charged for data usage.
**Where is our server located?**
Our servers are strategically placed in Beijing and Wuhan, ensuring low latency and fast connection speeds compared to foreign servers. This makes accessing international websites smoother and more reliable.
**Can I access Facebook, YouTube, and other foreign sites?**
Yes, you can access platforms like YouTube, Facebook, and others. For example, YouTube videos can be streamed in 1080p resolution without buffering issues.
**What is the bandwidth speed?**
Our servers offer unlimited bandwidth, and your actual speed depends on your school’s network capacity. You can test your speed at [neu.speed.neu6.edu.cn](http://neu.speed.neu6.edu.cn). Keep in mind that 1 Mbps equals approximately 128 KB/s.
**Can the network be shared?**
Yes, you can share the network by enabling Wi-Fi on your computer.
**Can it be used on a router?**
You can use your account on OpenWRT routers, but configuration may vary depending on the hardware and firmware. We provide standard configuration files, but you may need to do some research to set it up properly.
**Can I use it at home or outside the school?**
Yes, with IPv6, you can access the internet from anywhere. Using our account, you can get IPv6 connectivity even when you're on an IPv4 network. This means you can browse foreign websites like Google, YouTube, and Bilibili without restrictions, enjoying unlimited speed and data.
**Do I have an IPv6 network?**
To check if your device supports IPv6, go to "Network and Sharing Center" > "Change Adapter Settings" > Right-click on your connection > Properties > Check the box for "Internet Protocol Version 6 (TCP/IPv6)". If you don’t see it, refer to the tutorial in Appendix 1 for detailed steps.
**How to Enable IPv6 on Windows**
1. Right-click the network icon in the taskbar and select "Open Network and Sharing Center".
2. Click on "Change Adapter Settings".
3. Right-click on your active connection (e.g., Ethernet or Wi-Fi) and choose "Properties".
4. Uncheck "Internet Protocol Version 4 (TCP/IPv4)" and check "Internet Protocol Version 6 (TCP/IPv6)".
5. Click "Properties" again, then enter the DNS server address: `2001:778::37` (make sure the colon is in English mode).
6. Click OK and wait for the connection to establish. Some systems may require a restart.
After setting it up, visit [ipv6.jmu.edu.cn](http://ipv6.jmu.edu.cn) to verify your IPv6 connection. You should see a tiger image if everything is working. Additionally, you can try [tv.byr.cn](http://tv.byr.cn) for IPv6-based TV streaming.
