14 14 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Assigning Addresses  The importance of using a structured process to assign IP addresses to hosts and the implications for choosing private vs. public addresses

15 15 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Assigning Addresses  How end user devices can obtain addresses either statically through an administrator or dynamically through DHCP

16 16 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Assigning Addresses  Which types of addresses should be assigned to devices other than end user devices

17 17 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Assigning Addresses  The process for requesting IPv4 public addresses, the role ISPs play in the process, and the role of the regional agencies that manage IP address registries

18 18 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Assigning Addresses  Different types of ISPs and their roles in providing Internet connectivity

19 19 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Assigning Addresses  Changes made to the IP protocol in IPv6 and the motivation for migrating from IPv4 to IPv6.

20 20 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Determine the network portion of the host address and the role of the subnet mask  How the subnet mask is used to create and specify the network and host portions of an IP address

21 21 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Determine the network portion of the host address and the role of the subnet mask  Use of the subnet mask and ANDing process to extract the network address from the IP address.

28 28 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Calculating Addresses  Given a pool of addresses and masks, assign a host parameter with address, mask and gateway

29 29 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Calculating Addresses  Given a diagram of a multi-layered network, address range, number of hosts in each network and the ranges for each network, create a network scheme that assigns addressing ranges to each network

30 30 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Testing the Network Layer  The general purpose of the ping command, tracing the steps of its operation in a network, and using the ping command to determine if the IP protocol is operational on a local host

31 31 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Testing the Network Layer  Using ping to verify that a local host can communicate with a gateway across a local area network

32 32 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Testing the Network Layer  Using ping to verify that a local host can communicate via a gateway to a device in remote network

33 33 © 2007 Cisco Systems, Inc. All rights reserved.Cisco Public Testing the Network Layer  Using tracert/traceroute to observe the path between two devices as they communicate and trace the steps of tracert/traceroute 's operation
