When running a scan on your computer, you find that a session has been established with a host at the address 208.85.40.44:80. Which Application layer protocol is in use for this session? What command-line utility might you use to determine which computer is the host?

The Application layer protocol that is typically used for communication over port 80 is HTTP (Hypertext Transfer Protocol). Hence, it is likely that an HTTP session is established with the host at the address 208.85.40.44:80.

To determine which computer is the host at that IP address, you can use the command-line utility called "ping". The ping utility sends an Internet Control Message Protocol (ICMP) Echo Request to the specified host and receives an ICMP Echo Reply if the host is available. In this case, the command `ping 208.85.40.44` can be used to identify the host.

To determine the Application layer protocol in use for the session with the host address 208.85.40.44:80, you can look at the port number. In this case, port 80 is being used, which is the default port for the HTTP (Hypertext Transfer Protocol) protocol. Therefore, the Application layer protocol in use for this session is HTTP.

To determine which computer is the host with the IP address 208.85.40.44, you can use the command-line utility "ping" in the following manner:

1. Open the command prompt on your computer.
2. Type "ping 208.85.40.44" (without quotes) and press Enter.
3. The ping utility will send a request to the specified IP address and wait for a response.
4. If you receive a response, it means that your computer can communicate with the host at that IP address. The response will also include the IP address of the host computer.

Note that the "ping" command-line utility may be slightly different depending on the operating system you are using, but the general usage described above should be applicable for most systems.
