1. Chapter 8: Configuring Networking

2. Exploring the Network and Sharing Center 2

3. Network and Sharing Center Network Discovery File Sharing Public Folder Sharing Printer Sharing Media Sharing Domain –Private Network –Public Network 3

4. Understanding IP IPv4 –Current Standard –4,294,967,296 IP addresses IPv6 –New Standard –2^128 IP Addresses 4

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 5

6. IPv4 Subnets Logical grouping of computers based IP 6 P ART OF A DDRESS D ECIMAL B INARY IP address192.168.65.35 11000000.10101000.01000001.00100011 Subnet mask255.255.255.0 11111111.11111111.11111111.00000000 Network portion192.168.65.0 11000000.10101000.01000001.00000000 Client portion0.0.0.35 00000000.00000000.00000000.00100011

7. IPv4 Default Gateway Router of last resort Used for communication off the local subnet 7

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 8

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 9

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 10

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) 11

12. IP Configuration Client for Microsoft Networks File and Print Sharing for Microsoft Networks Internet Protocol DNS Server DHCP 12

13. IP Autoconfiguration IPv4 –168.254.x.y IPv6 –Chooses an address in the connected subnet automatically 13

14. VPN Connections Allows you to connect to remote networks Server name or address Encryption, if any VPN Type –L2TP –PPTP 14

15. Remote Desktop Enabled via System Properties Remote Desktop Client NLA Settings must match 15

16. Windows Remote Assistance Connect via Wizard Invitation File Remote Control Send and Receive Files Chat 16

17. Wireless Networking IEEE 802.11 Standard Ad-Hoc vs. Infrastructure SSID – Network name Security Type –WEP –WPA –WPA-Enterprise 17

18. Configuring IPSec Client (Respond Only) Server (Request Security) Server (Require Security) 18

19. Windows Firewall Blocks incoming and outgoing requests Exceptions can be configured for applications or ports 19
