1. After DenisDNS gets a response from the recursive DNS server (i.e., the WSU DNS Server in this case), does it properly check the IP address of the recursive DNS server?
2. Does DenisDNS properly check the transaction ID in responses from DNS server?
3. After DenisDNS gets a reply from the recursive DNS server (i.e., the WSU DNS Server in this case), does it actually check whether the domain name in this response match the domain in the query?
4. If DenisDNS gets a response, how long will it cache it for?
1. Please give the snippet where the TCP IP stack implement the random number generator and briefly explain if it is flaw.
2. Please give the snippet where this implementation generates the initial value of the sequence number for a new TCP connection.
3. How does the initial value of the sequence number of a new TCP connection change? To be more specific, briefly explain how it is relevant to the random number generator.
4. Is the initial value of the sequence number predictable in this implication? If so, how can you predict such value in practice? If not, please justify.
