Introducing the Domain Name System (DNS)
The process of obtaining an IP address for a computer name (for example, “ComputerA”) is called name resolution.
Using the Routing and Remote Access Service (RRAS)
The routing service included with Windows Server 2008 is better suited for a smaller network or one with a small amount of network traffic that needs to pass between subnets.
Introducing Network Access Protection (NAP)
Network Access Protection is a new feature in Windows Server 2008 that allows network administrators to specify one or more policies that define the conditions under which network access will or will not be permitted.
Network class Starting address Ending Address CIDR Block Bitmask
Class C 192.0.0.0 223.255.255.255 /24 255.255.255.0
Introducing TCP/IP Addressing
IPv4 addresses are commonly represented using what is called dotted-decimal notation, in which the decimal value of each byte is shown, using periods to separate the bytes.
Introducing IP version 6 (IPv6)
IPv6 address notation is noticeably different from the dotted-decimal of IPv4, using eight groups of four hexadecimal digits, separated by colons. IPv6 includes a few other enhancements for performance and security. Notably, IP security through the use of IPSec is an integral part of IPv6, whereas it was an optional feature under IPv4
Configuring Basic Network Settings
As discussed in Lesson 1, each host on a TCP/IP network should be configured with a number of mandatory and optional configuration items, including:
Subnet mask
Default gateway
DNS/WINS servers
If this system will be a DHCP server, you should set a static IP address, because that will be required when you try to set up the DHCP server role.
A spanned volume is made up of free space from multiple physical disks.
GPT (GUID Partition Table) – This partition style is recommended for disks larger than 2TB, or disks that are used in Itanium computers
Configuring the DHCP Server Role
BOOTP, which is still
