使用IP地址识别您网站上的用户是否可靠？ [英] Is it reliable to use the IP address to identify a user on your website?
问题描述
这是我的情况。我是一个创建P2P慈善网站的项目的一部分，用户可以在这个网站上进行连接并互相捐款。由于网站的性质，我们知道诈骗者将会猖獗。我们有几个预防措施的想法，并提出了一个想法是将IP地址绑定到用户的帐户。这样做的原因是能够检测来自同一IP地址的某人何时创建多个帐户。
Here is my situation. I am part of a project creating a P2P charity website, where users connect and can give money to one another. Because of the nature of the site, we know scammers are going to be rampant. We have several preventative measure ideas, and one idea that came up was tying an IP address to the user's account. The reason for this would be to be able to detect when someone from the same IP address creates several accounts.
这可靠吗？为什么或者为什么不？我一直在谷歌上搜索，并发现了很多有关这个问题的矛盾观点。感谢您提供的任何帮助。
Would this be reliable? Why, or why not? I have been googling and found many conflicting ideas on the subject. Thanks for any help you can give.
推荐答案
不，它不可靠。因为：
- 没有专门为静态IP地址付费的住宅客户经常会看到他们的地址经常变化。我正在使用AT&T DSL，我看到我的IP地址平均每月平均变化两次
- 人们合法地共享互联网连接，无论他们是否在同一办公室使用不同的工作站T1线路，或者它们都连接到星巴克的同一个Wi-Fi热点，都将拥有相同的IP地址。
- 与上述相关，移动设备的人，如在咖啡店，机场，酒店等使用笔记本电脑连接到无线网络的人，他们访问的每个地点都会有不同的IP地址。
- 即使是住在一个地方的人使用静态IP地址可能会使用代理服务器或Tor等代理工具欺骗您的系统。这使得IP限制无法绕过。
- Residential customers who aren't specifically paying for a static IP address will often see their addresses change frequently. I'm on AT&T DSL and I see my IP address change roughly twice per month on average
- People legitimately sharing an internet connection, whether they're using different workstations in the same office with a T1 line, or they're all connected to the same Wi-fi hotspot at Starbucks, will all have the same IP address.
- Related to the above, people who are mobile, such as people who use laptops to connect to Wi-fi at coffee shops, airports, hotels, etc, will have a different IP address for each location they visit.
- Even people who stay in one place with a static IP address can spoof your system by using a proxy server or a proxy tool like Tor. This makes IP restrictions trivial to bypass.
