The client domain refers to the domain name used by the client.
Example: in the URL http://www.website.com, "website.com" is the domain name.
It is the actual presence on the Internet represented by a website. A web domain name is a substitute that replaces the Internet Protocol (IP) address. For example, we can replace the IP address 126.96.36.199 with a domain name such as www.study.com.
