Transcribed Image Text:Consider a home network connected to the Internet through a single home router that supports
the Network Address Translation (NAT) protocol. The ISP is only providing a single public IP
address to the owner of this network (82.7.30.73). Let us assume that one of the connected home
devices with IP address 192.168.0.1 has an open connection from source port 30000 to a web
server with IP address 172.217.169.4. The source IP and port of the incoming TCP segments that
the web server sees could be:
192.168.0.1, 30000
82.7.30.73, 5555
192.168.0.1, 5555
172.217.169.4, 80

The first line of a HTTP request from some client to some server is basically made of where the web page file path is added. The path is shown as folders separated by slash. Q2. If an HTTP server responds to a client request and the response is a success, what is the http code and string that marks a success response? Must provide the code and the string as they appear in TCPDump or Wireshark traces. (note: use upper case for the string and also proper spacing in you answers. Keep the order of the string and the code as seen in TCPDump) Answer: code and string that marks a success response Q3. What http header field is used to identify an address of a web page (i.e. the URI) that linked to the resource currently being requested. This field indicates the last page the user/requester was on by the time they link to the requested page. Answer: The field that indicates the last page the user/requester was on is Q4.

The 28 after slash tells the first 28 bits of the given IP are network ID bits, which also implies the rest of 32-28 or 4 bits of the given IP are host ID bits. In other words, subnet mask /28 is equivalent to 255.255.255.240 in dot-decimal format. In the answer of this question, find the minimum IP of the host range, and find maximum IParrow_forward

Suppose that this web server is able to maintain persistent connections and responds to requests from both Host A and Host B. Is Host C sending all of the requests over the same connection, or are there many sockets in use? Do each of them have port 80 even though they are broadcast over separate sockets? It's something you need to discuss and provide some clarification on.arrow_forwardCan someone please help me with this?

- An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all O's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network? Type your answer.arrow_forwardEthernet, for example, is a connectionless protocol that specifies the path taken by a packet between its source and destination addresses. However, a protocol that is connection-oriented, such as ATM, specifies the path taken by a cell using virtual connection IDs (VPIs and VCIs).

An authentication is requested by the client, which contains the station ID (typically the MAC address). This is followed by an authentication response from the AP/router containing a success or failure message. An example of when a failure may occur is if the client's MAC address is explicitly excluded in the AP/router configuration. a. What are the benefits of this authentication scheme? b. What are the security vulnerabilities of this authentication scheme?arrow_forward
