When working with websites, a "binding" is a combination of protocol (http, ftp, https, etc.), IP address, TCP/IP port, and hostname (basically a domain name). In IIS 10, protocols are called "types" of bindings. Bindings are associated with websites that enable IIS to correctly route incoming traffic to the correct website. The IIS binding implementation also allows for multiple bindings per site.
IIS bindings use the following shorthand notation:
<protocol><IP address>:<port>:<hostname>
For example, site binding for http://www.demovpstest.com looks like this:
http://192.168.2.152:80:www.demovpstest.com

Step 7: In the IP address field, select the IP address you want to assign to the website.
Step 8: Enter the port number you want to run your website in the Port field. By default, the website runs on port 80. Here, we have set port 80 as an example.
Step 9: In the Hostname field, enter the name of your website with www or without www, which you want to add. Here, we have entered demovpstest.com as an example.
