Lesson 5: Set Network Configuration Mac Addressing, Ip Addressing, Subnetting
Embedded Files
After going through this lesson, you are expected to:
1. Understand what is MAC Address, IP Address, Subnet Mask
2. To identify IP address classes
3. To assign static and dynamic IP Address
Basic network concepts
Bandwidth - It describes the maximum rate of data across a given path. It is also the amount of data transmitted within a fixed period. In addition, internet bandwidth and internet speed are different from each other.
Internet bandwidth determines how much data can be downloaded or uploaded from your computer or device whereas internet speed determines how fast the data can be uploaded or downloaded from your device or computer. Bandwidth is measured in bits per second and has three units of measurement. They are bps (bits per second), kbps (kilobits per second), and Mbps (megabits per second).
MAC Address (Media Access Control)
MAC Address (Media Access Control)
It is a physical address assigned to the host’s NIC (network interface controller). The following are the steps on how to see your MAC address using ipconfig or ipconfig /all:
1. Type CMD (Command Prompt)
2. Command Prompt Window will appear
3. Type: C:\Users\Teachers>ipconfig /all
IP Address
IP Address
It is used to identify a device on the network. A unique IP address is given to each device in the network for the network device to communicate with each other.
IP Structure
IP Structure
• IP Address consists of 4 bits • Each section is 8 bit long • Each section can range from 0-255 e.g. 192.168.1.1
IP Classes
IP Classes
The network portion of an IP address is indicated by the subnet mask which is also a dotted decimal number. There is a default subnet mask that is mapped to the first three classes of IP addresses:
• 255.0.0.0 Class A: the first octet is the network portion
• 255.255.0.0 Class B: the first two octets are the network portion
• 255.255.255.0 Class C: the first three octets are the network portion
Static vs Dynamic IP Address
Dynamic IP address
Dynamic IP address
can change automatically
Static IP address
Static IP address
intended not to change and must be changed manually)
Assigning IP Address
Assigning IP Address
1.Press windows (windows logo from your keyboard) + R and Type ncpa.cpl then click OK or press ENTER
2. Right-click on your local adapter and select Properties
3. In the Local Area Connection Properties window select Internet Protocol Version 4 (TCP/IPv4) then click the Properties button.
4. 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.
