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 in use for this session is likely HTTP (Hypertext Transfer Protocol), as port 80 is commonly used for HTTP communication.
To determine which computer is the host at the given IP address, you can use the command-line utility called "nslookup" (short for Name Server Lookup). The nslookup command allows you to query DNS (Domain Name System) information to obtain the hostname associated with a specific IP address.
To determine the host, you can run the following command in the command prompt or terminal:
nslookup 208.85.40.44
This will provide you with the corresponding hostname of the IP address, indicating which computer is the host.
To determine which Application layer protocol is in use for the session established with the host at the address 208.85.40.44:80, you need to identify the port number 80. Port 80 is commonly associated with the Hypertext Transfer Protocol (HTTP) for web traffic.
To determine which computer is the host at the given IP address, you can use the command-line utility called "tracert" or "traceroute" on different operating systems.
On Windows:
1. Press the Windows key + R to open the Run dialog box.
2. Type "cmd" and press Enter to open the command prompt.
3. In the command prompt, type "tracert 208.85.40.44" and press Enter.
4. The tracert command will start tracing the route to the given IP address and display the intermediate hosts with their IP addresses.
On macOS and Linux:
1. Open the Terminal application.
2. In the terminal, type "traceroute 208.85.40.44" and press Enter.
3. The traceroute command will start tracing the route to the given IP address and display the intermediate hosts with their IP addresses.
Using the tracert or traceroute utility should help you determine which computer is the host at the specified IP address.
