Windows modifies local hosts table use domain name to access local site

1. Set Web site IIS site properties IP address is "127.0.0.1" or "(All Unassigned)"

2. Notepad opens the C:/windows/system32/drivers/etc/hosts file, adds "127.0.0.1 www.111cn.net" the domain name and the IP to map in the following format

3. Open the browser and use Www.111cn.net to access the local site

Principle: C:/windows/system32/drivers/etc/hosts is a local domain name resolution file, in the browser input a URL, window first check this file has no domain name on the IP, there is a request for this IP, no words will be to DNS (Domain Name System , you can see the DNS server IP address in the local connection TCP/IP properties to continue to seek resolution until you receive the correct IP and then broadcast the HTTP request.
