CHAPTER 21

---

1. You can use the procedure described in Exercise #1 of Chapter 15 to obtain the IP address of your computer.

2. In class B IP address format, 14 bits are used for network ID and 16 bits for host ID. Hence, 2¹⁴ networks can be addressed, and each network can have 2¹⁶ hosts.

3. In class C IP address format, 24 bits are used for network ID and 8 bits for host ID. Hence, 2²⁴ networks can be addressed and in each network 2⁸ hosts.

4. The maximum number of addresses supported by IP Version 6 is 340,282,366,920,938,463,463,374,607,431,768,211,456.
