12. There are three types of addresses within the address range of each IPv4 network. These are:

13. What is the purpose of the host portion of an IPv4 address?

14. What is the purpose of the IPv4 broadcast address?

15. It is common in many addressing schemes to use the first host address for what device or purpose?

16. What does the network address in a range of addresses represent?

17. What is ANDing?

18. There are four basic equations to AND numbers. Complete the equations below.

20. Explain static assignment of IP addresses.

21. What types of devices are typically assigned static addresses?

22. Dynamic assignment of IP addresses is done using a protocol known as Dynamic Host Configuration Protocol (DHCP). What information does DHCP automatically assign to local hosts?

23. DHCP is generally the preferred method of assigning IPv4 addresses to hosts on large networks. Why?

24. IF DHCP is enabled on a computer what command can be used to view the local IP address?
