The domain name in a Uniform Resource Locator (URL) identifies the server on which the web page can be found.

Example: In the URL "http://www.example.com/index.html":

"http" is the protocol.

"www.example.com" is the domain name.

"/index.html" is the resource path ID.

The other options:

The protocol specifies the communication method.

The resource path ID specifies the specific page or resource on the server.

The IP address is not typically visible in the URL itself but can be resolved via DNS.

Therefore, the domain name is the correct part that identifies the server.
