It is generally undesirable to have conflicts, such as different IP addresses to map to the same name or different organizations claiming the same domain name. Such conflicts are prevented by assigning responsibilities to different parties that act in a coordinated way. Check all of the entities mentioned below that help maintain the correctness of the DNS database.

a. IANA is an international organization that is responsible for coordinating assignment of IP addresses and domains. It authorizes

b. Registrars to handle top-level domains. Registrars are responsible for registering domains (within their top level domain) to organizations, and for storing Resource Records that map each registered organization domain to the the authoritative name server of that domain.

c. Authoritative name servers are responsible for names and addresses within their own organization's registered domain.

d. Laws and Courts: if anyone tries to claim a domain name or IP address they are not entitled to, the registrars's typical action is to take that person or organization to court.

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called.write a constructor for the above class that initialized both variables to zero.write a tostring to display both the tank and speed when the car is printed.modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter.write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.
