11. What is the address space in each of the following systems? a. System with 8-bit addresses i. 28 = 256 b. System with 16-bit addresses i. 216 = 65,536 c. System with 64-bit addresses i. 264 = 1.844674407 x 1019 12. An address space has a total of 1024 addresses. How many bits are needed to represent an address? i. Log21024 = 10

13. An address space uses the three symbols 0, 1, and 2 to represent addresses. If each address is made of 10 symbols, how many addresses are available in this system? i. 3 possible options for 10 symbols, so 3 10 = 59,049 16. Find the class of the following IP addresses (page 552) a. 208.34.54.12 i. Class C b. 238.34.2.1 i. Class D c. 114.34.2.8 i. Class A d. 129.14.6.8 i. Class B 18. Find the netid and the hostid of the following IP addresses. (page 553) a. 114.34.2.8 i. Netid = 114 Hostid = 34.2.8 b. 132.56.8.6 i. Netid = 132.56 Hostid = 8.6 c. 208.34.54.12 i. Netid = 208.34.54 Hostid = 12

21. An organization is granted the block 16.0.0.0/8. The administrator wants to create 500 fixed -length subnets. a. Find the subnet mask i. 500 subnets means we need log2500 bits reserved in addition to the current mask, so 8+9 = 17 bits total. The Design of Networks Page 1
