How to make Windows7 only access the specified webpage

  
Some time ago, bank customers opened an experience zone, which is to let everyone experience their online banking, but found that many users have Baidu on the computer, Weibo, but they only want Let users access their online banking system.
Method 1 Modify the Hosts File The
hosts file is located in the Windows/system32/drivers/etc/directory and is used to control domain name access. I thought of the way to modify the hosts file, so that the DNS domain name resolution sites point to 127.0.0.1, as follows:
127.0.0.1 www.baidu.com
127.0.0.1 www.qq.com
... ...
However, it is impossible to write all the domain names. Someone asks 127.0.0.1 * Can you? The answer is no, because the hosts file does not support wildcards.
So this method is theoretically feasible, but it is not practical.
Method 2 Control through Hosts file and network settings
1. Set the DNS server to 127.0.0.1 in the network settings, network link status -> TCP/IPv4 -> Properties -> Preferred DNS server - > 127.0.0.1
At this time, you will find that opening a browser to access any web page through a domain name is not acceptable (but it can be done by IP, but this can at least mask out 95% of users, because
most The user only remembers the domain name, it is impossible to remember the server IP).
2. Modify the hosts file to specify the domain name that is not prohibited. For example: 61.135.169.125 www.baidu.com, at this time, when visiting www.baidu.com, it is not through the DNS server, but directly mapped to 61.135.169.125.
The above methods can be tried, although not a perfect solution, but it is very simple.
