  1. Module 3: Configuring Basic TCP/IPv4 Settings

  2. Module 3: Configuring Basic TCP/IPv4 Settings • Overview of the TCP/IP Protocol Suite • Overview of TCP/IP Addressing • Name Resolution • Dynamic IP Addressing • TCP/IPv4 Tools

  3. Lesson 1: Overview of the TCP/IP Protocol Suite • TCP/IP Architecture • How the TCP/IP Model Relates to the OSI Model • Transport Layer Protocols • Common Application Layer Protocols • What Is an RFC?

  4. TCP/IP Architecture IPv4 IPv6 ARP IGMP ICMP TCP/IP Protocol Suite Application HTTP FTP SMTP DNS POP3 SNMP Transport TCP UDP Internet Network Interface Ethernet Token Ring Frame Relay ATM

  5. How the TCP/IP Model Relates to the OSI Model IPv4 IPv6 ARP IGMP ICMP OSI TCP/IP TCP/IP Protocol Suite Application Application Presentation DNS POP3 HTTP FTP SMTP SNMP Session Transport Transport TCP UDP Network Internet Data-Link Ethernet Token Ring Frame Relay ATM Network Interface Physical

  6. Transport Layer Protocols TCP: • Connection oriented • Reliable UDP: • Connectionless • Unreliable

  7. Common Application Layer Protocols Some common application layer protocols are: • HTTP/HTTPS • RPC over HTTP • FTP • RDP • SMB • SMTP • POP3

  8. What Is an RFC? Maturity levels: • Proposed standard • Draft standard • Internet standard A Request for Comments (RFC) is description of network functionality Status levels: • Required • Recommended • Elective • Limited use • Not recommended

  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 Address192.168.2.180 IP Address192.168.2.181 IP Address192.168.2.182 IP Address192.168.1.181 IP Address192.168.1.180 IP Address192.168.1.182

  11. What Is a Subnet Mask? 168 255 168 255 44 44 0 0 32 192 255 192 w w w x x x y y y z z z IP address Subnet mask Network ID

  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

  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 Microsoft.com DNS Server .com DNS Server What is the IP address of www.microsoft.com? Root DNS Server Local DNS Server 207.46.230.219 Workstation

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

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

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

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

  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 IP Address1 IP Address1 IP Address2 IP Address3 . . . IP AddressN IP Address2 DHCP Client DHCP Server DHCP Database

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

  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? Server found? DHCP client without an IP address attemptsto locate DHCP Server DHCP server assigns address to client Yes No No APIPA address is assigned Yes APIPA configuredand enabled? User-configuredalternate configurationspecified? User-configured IP address is assigned Yes No User-configured IP address is not assigned

  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. What Is IPConfig? IPConfig is used to display IP configuration information and control the DNS resolver cache

  32. What Is NETStat? NETStat is used to display protocol statistics and current TCP/IP network connections

  33. What Is NBTStat? NBTStat is used to display NetBIOS information on the local computer

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

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

  36. Lab: Configuring Basic TCP/IPv4 Settings and Validating TCP/IPv4 Connectivity • Exercise 1: Configuring a Dynamic IP Address • Exercise 2: Configuring a Static IP Address • Exercise 3: Testing DNS Configuration • Exercise 4: Connecting to a Web Application Estimated time: 60 minutes

  37. Lab Review • Why would you use NSLookup to verify DNS records rather than using Ping? • Why would you configure a Web site to run on a non-standard port number?

  38. Module Review and Takeaways • Review Questions • Real-world Issues and Scenarios • Best Practices • Tools
