Exercise 4 Objectives Statement Purpose Describe Dotted Decimal

Exercise # 4 Objectives / Statement Purpose: Describe Dotted Decimal notation of IPV 4 addressing Describe Binary to Decimal Conversion Explain how to set a manual IP address of a computer Activity Outcomes: The student should know the Dotted Decimal notation of IPV 4 addressing The student should know the Binary to Decimal and Vice versa Conversion The students should know how to set a manual IP address of a computer Instructions: Dot-decimal notation is a presentation format for numerical data. It consists of a string of decimal numbers, each pair separated by a full stop (dot). An IPv 4 address is a 32 -bit address that uniquely and universally defines the connection of a device (for example, a computer or a router) to the Internet

Physical addresses A physical address is the hardware-level address used by the Ethernet interface to communicate on the network. Every device must have a unique physical address. This is often referred to as its MAC (Media Access Control) address. An Ethernet physical address is six bytes long and consists of six hexadecimal numbers, usually separated by colon characters (: ).

A logical address is a network-layer address that is interpreted by a protocol handler. Logical addresses are used by networking software to allow packets to be independent of the physical connection of the network, that is, to work with different network topologies and types of media. In computer networking, port numbers are part of the addressing information used to identify the senders and receivers of messages. Port numbers are associated with TCP/IP network connections. They allow different applications on the same computer to share network resources simultaneous

IP Addresses In order for systems to locate each other in a distributed environment, nodes are given explicit addresses that uniquely identify the particular network the system is on and uniquely identify the system to that particular network. These addresses are actually 32 -bit binary numbers, consisting of the two sub addresses (identifiers) mentioned above which, respectively, identify the network and the host to the network, with an imaginary boundary separating the two. An IP address is, as such, generally shown as 4 octets of numbers from 0 -255 represented in decimal form instead of binary form. Task 1: IPv 4 Addressing

Windows 7 Right click on the icon for network in task bar and choose open Network and Sharing Center, click on Change adapter settings. This will be the same on Windows 7 or 8. x.

In the Local Area Connection Properties window highlight Internet Protocol Version 4 (TCP/IPv 4) then click the Properties button.

Now select the radio button Use the following IP address and enter in the correct IP, Subnet mask, and Default gateway that corresponds with your network setup. Then enter your Preferred and Alternate DNS server addresses. Here we’re on a home network and using a simple Class C network configuration and Google DNS. Check Validate settings upon exit so Windows can find any problems with the addresses you entered. When you’re finished click OK. Now close out of the Local Area Connections Properties window.

Open the Command Prompt and do an ipconfig to verify the changes were successful.

Change the following IPv 4 addresses from binary notation to dotted-decimal notation. Solution We replace each group of 8 bits with its equivalent decimal number (see Appendix B) and add dots for separation
