    Section 6.6: IP Configuration

    Summary


    This section explores configuration settings required to connect to a TCP/IP network. Concepts covered include:


    • Required parameters:

      • IP address

      • Subnet mask

      • Default gateway

      • DNS server

      • Host name

    • Tools to manage network connections and network configuration

    Students will learn how to:

    Lecture Focus Questions:

    • What service is used to automatically assign TCP/IP configuration information to hosts?

    • When assigning IP addresses to hosts, which portions of the configuration must match values used by other hosts in the same subnet?

    • A router has two network interfaces, each connected to a different subnet. When configuring the default gateway value on a host, which IP address would you use?

    • What capability does the DNS server address provide? What would happen if the computer was not configured to use a DNS server?

    Section 6.7: 802.11 Wireless

    Summary


    In this section students will learn the basics of wireless networks. Concepts covered include:

    • Wireless networking architecture:

      • Devices

      • Connection methods

      • SSID (Service Set Identifier)

    • IEEE standards

      • 802.11a

      • 802.11b

      • 802.11g

      • 802.11n

    • 802.11n technologies to improve speed or distance

      • Multiple Input Multiple Output (MIMO)

      • Channel bonding

    • Details about wireless networks

    • Authentication methods for wireless networks

      • Open

      • Shared key

      • 802.1x

    • Standards to provide security for wireless networking:

      • Wired Equivalent Privacy (WEP)

      • Wi-Fi Protected Access (WPA)

      • Wi-Fi Protected Access 2 (WPA2) or 802.11i

    • Methods to limit access:

      • Change the administrator account name and password

      • Change SSID from defaults

      • Enable MAC address filtering

      • Disable DHCP
