Chapter 8: Configuring Networking

2

Exploring the Network and Sharing Center

3

Network and Sharing Center

• Network Discovery• File Sharing• Public Folder Sharing• Printer Sharing• Media Sharing• Domain

– Private Network– Public Network

4

Understanding IP

• IPv4– Current Standard– 4,294,967,296 IP addresses

• IPv6– New Standard– 2^128 IP Addresses

5

IPv4

• Unique IP address identifies each PC

• Ex….192.168.25.65• Each part and octet• Determining the Network and

Client portions of an IP Address

6

IPv4 Subnets

• Logical grouping of computers based IP

PART OF ADDRESS

DECIMAL BINARY

IP address 192.168.65.35 11000000.10101000.01000001.00100011

Subnet mask 255.255.255.0 11111111.11111111.11111111.00000000

Network portion 192.168.65.0 11000000.10101000.01000001.00000000

Client portion 0.0.0.35 00000000.00000000.00000000.00100011

7

IPv4 Default Gateway

• Router of last resort• Used for communication off the

local subnet

8

IPv4 Reserved Addresses

• Private Address Spaces– 10.0.0.0 to 10.255.255.255 – 172.16.0.0 to 172.31.255.255– 192.168.0.0 to 192.168.255.255

• Loopback Address Space– 127.0.0.0 to 127.255.255.255

• Autonetting Addresses– 169.254.0.0 – 169.254.255.255

9

IPv6

• Similar to v4 with a different address space

• 128-bit addresses• Eight groups of four hexadecimal

characters• Ex…

fe80:0000:0000:0000:dd44:f454:0a35:d1f6

10

IPv6 Subnets

• Left most bits make the subnet• Right most bits are the client• Default 64 bits each• IPv6 Default Gateway

– Same as IPv4 except for the address format

11

IPv6 Reserved Addresses

• Private Address Space– Any address starting with

0000:0000• Loopback Address

– 0000:0000:0000:0000:0000:0000:0000:0001

– ::1 (Shorthand)

12

IP Configuration

• Client for Microsoft Networks• File and Print Sharing for

Microsoft Networks• Internet Protocol• DNS Server• DHCP

13

IP Autoconfiguration

• IPv4– 168.254.x.y

• IPv6– Chooses an address in the

connected subnet automatically

14

VPN Connections

• Allows you to connect to remote networks

• Server name or address• Encryption, if any• VPN Type

– L2TP– PPTP

15

Remote Desktop

• Enabled via System Properties• Remote Desktop Client• NLA Settings must match

16

Windows Remote Assistance

• Connect via Wizard• Invitation File• Remote Control• Send and Receive Files• Chat

17

Wireless Networking

• IEEE 802.11 Standard• Ad-Hoc vs. Infrastructure• SSID – Network name• Security Type

– WEP– WPA– WPA-Enterprise

18

Configuring IPSec

• Client (Respond Only)• Server (Request Security)• Server (Require Security)

19

Windows Firewall

• Blocks incoming and outgoing requests

• Exceptions can be configured for applications or ports
