1. Which domain is used by your system, generic or country?
2. Why do we need a DNS system when we can directly use an IP address?
3. To find the IP address of a destination, we need the service of DNS. DNS needs the service of UDP or TCP. UDP or TCP needs the service of IP. IP needs an IP destination address. Is this a vicious cycle here?
4. If a DNS domain name is voyager.fhda.edu, how many labels are involved here? How many levels of hierarchy?
