1-Do routers have IP addresses? If so, how many? How many IP addresses does a computer have?
2-Consider a router that interconnects three subnets: Subnet A, Subnet B, and Subnet C. Suppose all the interfaces in each of the three subnets are required to have the prefix 223.1.17.0/24. Also, suppose that subnet A is required to support up to 60 interface, Subnet B is to support up to 90 interfaces, and subnet C is to support up to 12 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints.
3-Suppose that you purchase a wireless router and connect it to your cable modem. Also, suppose that your ISP dynamically assigns your connected device (your wireless router) one IP address. Also suppose that you have six PCs at home that use 802.11 to wirelessly connect to your wireless router. How are IP addresses assigned to the six PCs? Does your wireless router use NAT? Why or why not?
4-What is the 32-bit binary equivalent of 85.28.62.248?
5-Electronic mail represents a technology that is integrally woven in our daily lives as a means of communication. In two to three pages, provide an overview of this technology detailing among other things its implementation and the components necessary for its operation.
