1 Name Date Period TCP/IP Fundamentals Introduction For the Network+ Certification exam, you should be able to identify the class of an IP address, an APIPA IP address, and a private IP address as well as their subnet mask. You should know the function of the following network services: DHCP, DNS, NAT, ICS, WINS, ARP, and RARP. Also, you should be able to identify port numbers by their related service and identify the function of common TCPlIP troubleshooting utilities. Practice 11.1 Record the range and subnet mask of public IP addresses by class. Public IP Addresses Class Range Subnet Mask A B C Practice 11.2 Record the class (A, B, or C) and subnet mask of each of the following IP addresses : : : : : : : 61

APIPA IP Addresses Class Range Subnet Mask Practice 11.6 Match the network services to their definition Address Resolution Protocol (ARP) 2. Domain Name System (DNS) 3. Dynamic Host Configuration Protocol (DHCP) 4. Network Address Translation (NAT) 5. Reverse Address Resolution Protocol (RARP) 6. Windows Internet Naming Service (WINS) a. A protocol that translates private network addresses into an assigned Internet address, and vice versa. In other words, it allows an unregistered private network address to communicate with a legally registered IP address. b. A service that maps a MAC address to an IP address. c. A system that associates a host or domain name with an IP address, making it easy to identify and find hosts and networks. d. A service that resolves NetBIOS names to IP addresses. e. A service that assigns IP addresses automatically to the hosts on a network. f. A service that finds the MAC address of a host when the IP address is known.

It 2. ipconfig can be used to determine network problems such as excessive broadcasts on the network. 3. nbtstat It also allows the user to monitor network 4. netstat connections. 5. nlslookup b. Displays NetBIOS over TCP statistics. 6. ping c. Used to send a packet from one host to another on a network and then echo a return reply. 7. traceroutei tracert It is commonly used to quickly check the 8. winipcfg connection state of network media between two hosts on a network. d. Used to troubleshoot a path to a distant destination. This utility displays the approximate hop lapse times between points along the route. The amount of time delay can help analyze network failure or problems caused by excessive time delays. e. Lists IP addresses resolved to MAC addresses. It can be used to troubleshoot problems with multiple IP assignments and to solve host communication problems.. Used to query domain servers when seeking information about domain names and IP addresses. This is a convenient tool when looking for information about a particular domain or IP addresses. g. Used to verify TCP/IP settings on a Windows NT, 2000, and XP host. h. Used to verify TCP lip settings on a Windows 95, 98, and Me host.

6 Chapter 11 Review TCP/IP Fundamentals Name Date Period Score 1. The two types of IP addressing schemes are and addressing. 2. A(n) is an 8-bit or one byte value. 3. Each octet in an IPv4 address is composed of 0s and 1s. 4. An IPv4 address consists of a total of octets. 5. Each octet represents a decimal in the range of 0 through. 6. IP addressing is used to identify every or host on the network. 7. A Class network uses a subnet mask of The acronym ICS represents. 9. The acronym NAT represents. 10. To view the IP configuration settings at a Windows 98 workstation, you would type in the Run dialog box. 11. To view the IP configuration settings at a Windows XP workstation, you would type at the command prompt. 12. The acronym FQDM represents. 13. The Domain Name System associates a host or name with an IP address. 14. At the top of the Domain Name System structure is the. 15. Examples of top-level are.edu,.com, and.gov. 16. Two text files used to resolve NetBIOS names to IP addresses are and. 17. The acronym WINS represents. 18. The TCP and UDP protocols are directly associated with the layer of the OSI model. 19. In the encapsulation process, raw data is first divided into, and then encapsulated into, which are then encapsulated as at the data link layer. 20. The IP protocol is directly associated with the layer of the OSI model Continued Permission granted to reproduce for educational use only Chapter 11 TCP/IP Fundamentals 171

7 Name 21. Ethernet is directly associated with the and the layer of the OSI model. 22. DNS, DHCP, and similar upper-level protocols are associated with the,, and layers of the OSI model. 23. UDP and TCP are typically encapsulated by the protocol. 24. The Ethernet protocol adds the address during the encapsulation process. 25. The IP protocol adds the address during the encapsulation process. 26. A DHCP server has a(n) of IP addresses to draw from. 27. WINS is used to resolve names to IP addresses. 28. The acronym DHCP represents. 29. The purpose of a(n) server is to supply IP addresses automatically to network devices. 30. When a workstation s IP address is assigned automatically, it is referred to as a(n) IP assignment. 31. When a workstation s IP address is assigned manually, it is referred to as a(n) IP assignment. 32. The server sets a lease period for IP address assignments. 33. The acronym APIPA represents. 34. The first two octets of an IP address issued using the APIPA service is. 35. To identify network services, numbers are used. 36. The combination of a port number and an IP address creates a(n). 37. A Web server uses port for Web services. 38. FTP uses port and by default. 39. Port number assignments from 0 to 1023 are referred to as port numbers. 40. Port 110 is the default port used by service. 41. Port is the default port used by IMAP service. 42. Port 53 is used by default by the. 43. The command is used to display NetBIOS over TCP statistics. 44. The command uses the Internet Control Message Protocol to carry data Continued 172 Networking Fundamentals Instructor s Manual Permission granted to reproduce for educational use only

The UNIX/Linux operating systems use the command to query domain servers for information about domain names. 49. IPv6 is also referred to as IP addressing. 50. The loopback address for IPv4 is, and the loopback address for IPv6 is or :: Permission granted to reproduce for educational use only Chapter 11 TCP/IP Fundamentals 173
