9. Lesson 2: Overview of TCP/IP Addressing The Components of an IP Address What Is a Subnet Mask? What Is a Default Gateway? What Is DNS? Demonstration: Configuring a Static IP Address

10. The Components of an IP Address IP Address 192.168.2.182 IP Address 192.168.2.180 IP Address 192.168.2.181 IP Address 192.168.1.180 IP Address 192.168.1.182 IP Address 192.168.1.181

11. What Is a Subnet Mask? Network ID Subnet mask IP address xwyz 192 168 440 xwyz 255 0 xwyz 192 168 4432

12. What Is a Default Gateway? The default gateway: Is used to route packets to other networks Is used when the internal routing table on the host has no information about the destination subnet Use DHCP to deliver all IP Settings, including the default gateway, to client computers

13. What Is DNS? DNS is used to: Resolve host names to IP addresses Locate domain controllers and global catalog servers Used to resolve IP addresses to host names Used to locate mail servers during e-mail delivery

14. Demonstration: Configuring a Static IP Address In this demonstration, you will see how to configure a static IPv4 address

15. Lesson 3: Name Resolution Types of Names that Computers Use What Are DNS Zones and Records? How Internet DNS Names are Resolved Host Name Resolution Process Demonstration: Configuring Host Name Resolution What Is WINS? NetBIOS Name Resolution Process

16. Types of Names That Computers Use NameDescription Host names Up to 255 characters in length Can contain alphabetic and numeric characters, periods, and hyphens Part of FQDN NetBIOS names Represent a single computer or group of computers 15 characters used for the name 16th character identifies service Flat namespace

17. What Are DNS Zones and Records? A DNS zone is a specific portion of DNS namespace that can contain DNS records Records in forward lookup zones include: A SRV MX CNAME Records in reverse lookup zones include: PTR

18. How Internet DNS Names are Resolved Workstation 207.46.230.219 Local DNS Server What is the IP address of www.microsoft.com? Root DNS Server.com DNS Server Microsoft.com DNS Server

19. Host Name Resolution Process Local Host Name 1 1 DNS Server 3 3 NetBIOS Name Cache 4 4 WINS Server 5 5 Lmhosts File 7 7 Broadcast 6 6 DNS Resolver Cache 2 2

20. Demonstration: Configuring Host Name Resolution In this demonstration, you will see how to configure host name resolution

21. What Is WINS? Queries a WINS server 1 1 If not in use, then registers the NetBIOS name and associated IP address 3 3 Determines whether name is in use 2 2 Payroll WINS Server NetBIOS Name Registration Query ? ? OK

22. NetBIOS Name Resolution Process Local Host Name 5 5 DNS Server 7 7 Lmhosts File 4 4 Broadcast 3 3 NetBIOS Name Cache 1 1 DNS Resolver Cache 6 6 WINS Server 2 2

23. Lesson 4: Dynamic IP Addressing What Is DHCP? DHCP Address Renewal DHCP Configuration Options What Is Alternate Configuration? What s Automatic Private IP Addressing? Demonstration: Configuring Dynamic IP Addressing

24. What Is DHCP? Non-DHCP Client DHCP Client DHCP Server DHCP Database IP Address1 IP Address2 IP Address3. IP AddressN IP Address1 IP Address2 IP Address3. IP AddressN IP Address2 IP Address1 DHCP Client

25. DHCP Address Renewal DHCP Servers Lease-Holding DHCP Server DHCPREQUEST (Unicast) 1 1 1 1 2 2 DHCPREQUEST (Broadcast) 2 2 DHCPACK 3 3 DHCP Client 3 3 DHCP Server Non-DHCP Server

26. DHCP Configuration Options DHCP configuration options include: Creating scopes Start and end IP addresses Subnet mask Lease duration Router DNS server Exclusions Reservations

27. What Is Alternate Configuration? Yes No Yes No DHCP server assigns address to client APIPA address is assigned User-configured IP address is assigned User-configured IP address is not assigned Server found? User- configured alternate configuration specified? APIPA configured and enabled? DHCP client without an IP address attempts to locate DHCP Server

28. What Is Automatic Private IP Addressing? Automatic private IP addressing (APIPA): Is used if a DHCP server cannot be contacted Assigns IP addresses on the 169.254.0.0/16 network Cannot be used with: Active Directory Internet connectivity Multiple subnets DNS or WINS servers

29. Demonstration: Configuring Dynamic IP Addressing In this demonstration, you will you will see how to configure dynamic IP addressing

30. Lesson 5: TCP/IPv4 Tools What Is IPConfig? What Is NETStat? What Is NBTStat? What Is Netsh? Demonstration: Using TCP/IPv4 Tools

31. IPConfig is used to display IP configuration information and control the DNS resolver cache What Is IPConfig? OptionDescription /all Displays all IP address configuration information /releaseReleases a dynamic IPv4 address lease /renewRenews a dynamic IPv4 address lease /flushdnsPurges the DNS resolver cache /registerdns Refreshes DHCP leases and re-registers DNS names /displaydns Displays the contents of the DNS resolver cache

32. NETStat is used to display protocol statistics and current TCP/IP network connections What Is NETStat? OptionDescription -aDisplays all connections and listening ports -b Displays the executable involved in creating each connection and listening port -eDisplays Ethernet statistics -rDisplays the routing table -sDisplays per protocol statistics

33. What Is NBTStat? NBTStat is used to display NetBIOS information on the local computer OptionDescription -a View NetBIOS information for a specific NetBIOS name -c View the local cache of machine names and their IP addresses -nView local NetBIOS names -R Purges and reloads the remote cache name table -sLists sessions table by using IPv4 addresses

34. You can configure and monitor: Windows Firewall IP settings Interface settings IPSec Netsh is a command-line utility that is used to configure and monitor network settings What Is Netsh?

35. Demonstration: Using TCP/IPv4 Tools In this demonstration, you will see how to use: IPConfig NETStat Netsh
