Overview
+ + + + + + +
+ + + + + +
+ + The rapid growth of the Internet has astonished most observers. + One reason that the Internet has grown so quickly is due to the + flexibility of the original design. Without developing new + methodologies of IP address assignment, this rapid growth of the + Internet would have exhausted the current supply of IP addresses. In order to cope with a shortage of IP + addresses, several solutions were developed. One widely + implemented solution is Network Address Translation (NAT).

NAT is a mechanism for conserving registered IP addresses in large + networks and simplifying IP addressing management tasks. As a + packet is routed through a network device, usually a firewall or + border router, the source IP address is translated from a private + internal network address to a routable public IP address. This allows the packet to be transported over + public external networks, such as the Internet. The public address + in the reply is then translated back to the private internal + address for delivery within the internal network. A variation of + NAT, called Port Address Translation (PAT), allows many internal + private addresses to be translated using a single external public + address.

+

Routers, servers, and other key devices on the network usually require a static + IP configuration, which is entered manually. However, desktop + clients do not require a specific address but rather any one in a + range of addresses. This range is typically within an IP subnet. A + workstation within a specific subnet can be assigned any address + within a range while other values are static, including the subnet + mask, default gateway, and DNS server.

+

The Dynamic Host Configuration Protocol (DHCP) was designed to + assign IP addresses and other important network configuration + information dynamically. Because desktop clients typically make up + the bulk of network nodes, DHCP is an extremely useful timesaving + tool for network administrators.

+

Students completing this module should be able to:

+
    +
  • Identify private IP addresses as described in RFC 1918
    • +
  • Discuss characteristics of NAT and PAT
    • +
  • Explain the benefits of NAT
    • +
  • Explain how to configure NAT and PAT, including static + translation, dynamic translation, and overloading
    • +
  • Identify the commands used to verify NAT and PAT configuration
    • +
  • List the steps used to troubleshoot NAT and PAT configuration
    • +
  • Discuss the advantages and disadvantages of NAT
    • +
  • Describe the characteristics of DHCP
    • +
  • Explain the differences between BOOTP and DHCP
    • +
  • Explain the DHCP client configuration process
    • +
  • Configure a DHCP server
    • +
  • Verify DHCP operation
    • +
  • Troubleshoot a DHCP configuration
    • +
  • Explain DHCP relay requests
    • +
