CHS- IP addressing

Peer-to-Peer Network In a peer-to-peer network, devices are connected directly to each other without any additional networking devices between them.

Internet Protocols INTERNET PROTOCOLS are sets of rules governing communication within and between computers on a network. Protocol specifications define the format of the messages to be exchanged

IP Addressing An IP address is a number that is used to identify a device on the network. Each device on a network must have a unique IP address to communicate with other network devices



Subnet Mask Subnet Mask The subnet mask indicates the network portion of an IP address. Like the IP address, the subnet mask is a dotted-decimal number. Usually all hosts within a LAN use the same subnet mask. Table 3 shows default subnet masks for usable IP addresses that are mapped to the first three classes of IP addresses: 255.0.0.0: Class A, which indicates that the first octet of the IP address is the network portion 255.255.0.0: Class B, which indicates that the first two octets of the IP address are the network portion 55.255.255.0: Class C, which indicates that the first three octets of the IP address are the network portion

Here are the procedures in assigning an IP Address Subnet Mask on a windows base computer system: 1. Open the Control Panel’s Network Connections icon. 2. Open the icon representing your computer’s network connection. 3. Click the Properties button in the Status dialog box. 4. From the list of items, choose Internet Protocol (TCP/IP). 5. Click the Properties button. The Internet Protocol (TCP/IP) Properties dialog box appears. 6. Type the IP address for your computer. Enter the appropriate IP Address in the IP address section.

Here are the procedures in assigning an IP Address on a IP Address windows base computer system: 7. Type a subnet mask. The value used on a local network is commonly 255.255.255.0, but it can be different, such as 255.255.255.127. 8. Type the default gateway address. The default gateway is the router, so type the router’s address. 9. Click OK to confirm the settings. 10. Close all other open dialog boxes and windows.

Assigning a Dynamic IP Address IP Address If more than a few computers comprise the LAN, manually configuring IP addresses for every host on the network can be time-consuming and prone to errors. In this case, using a Dynamic Host Configuration Protocol (DHCP) server would automatically assign IP addresses and greatly simplify the addressing process. Dynamic Host Configuration Protocol (DHCP) is a software utility used to dynamically assign IP addresses to network devices. This dynamic process eliminates the need to manually assign IP addresses.

Assigning a Dynamic IP Address IP Address These are the IP address information that a DHCP server can assign to hosts: • IP address • Subnet mask • Default gateway • Optional values, such as a Domain Name System (DNS) server address The DHCP server receives a request from a host. The server then selects IP address information from a set of predefined addresses that are stored in a database.

Ping IP Address The ping is a Command Prompt command used to test the ability of the source computer to reach a specified destination computer. Ping Command Syntax Using the ping Command Ping is one of your most important tools in troubleshooting Internet problems. It shows you whether the Domain Name Server is working, whether the computer you are trying to talk to is reachable, and how long it takes to get there. It does this at a very low level — only the most basic Internet functions have to be up and running. 1) Click on Start Button, then type cmd (command prompt) on the search box. 2) A black screen will appear as shown in the figure below. 3) Type ping followed by the IP address you desire to verify. The figure below shows the screen of the ping command and its output. This output shows several things:

FILE SHARING IP Address 1. Right “click” the folder you want to share then go to “Properties” 2. On the “Sharing Tab” Click “share” 3. Choose “everyone” Then click “add” (change permission level to “read and write” then click share. 4. Click “Advanced Sharing”, then click “ share this folder” then click “ok” 5. Then close

REMINDERS! IP Address 1.Turn off Windows Firewall 2.Turn on Network Discovery 3.Turn on Public folder sharing 4.Turn on File and Printer sharing 5.Turn off Password Protected sharing
