How To Change or Add IP Address On Your Windows Machine
What Is An I.P Address
As an important distinction to identify a computer machine connected to a network an Internet Protocol (I.P) is used and not the machine itself. Transmission Control Protocol / Internet Protocol (TCP/IP) uses a 32 bit address to identify a machine on a network and to the network it is attached. IP address is the set of number we usually see on our workstation or terminals connected to the network such as 192.168.1.1, these IP address should be unique to every workstation to be able to establish a connection otherwise there would be an IP conflict on the network in which the machine is attached. IP addresses are 4 sets of 8bit for a total of 32 bits these bits are separated by period and are written out in their decimal equivalent.
The network Information Center (NIC) assigns the I.P address, but if not connected to the internet the network can determine its own numbering through DHCP or manually assigning a IP address. There are five classes of I.P addresses with each used depending on the size of the network. These classes are Class A, Class B, Class C, Class D and Class E. The class can be determined from the first three (high-order) bits.
|Class||Leading Bits||Network||Local Address||Start Address||End Address|
How to Change or Add IP Address
To be able to connect to your Local Area Network that don’t use Dynamic Host Configuration Protocol (DHCP) servers you have to manually input the I.P address in your TCP/IP configuration on your Windows system but for server or router that is configured to use DHCP you don’t have to assign I.P address to your machine as the DHCP server will assign the I.P address automatically. There are instances that you may need to configure your system TCP/IP to be able to connect to your existing Local Area Network or to the internet, here are basic guide on how to change or add an IP address to your computer.
- In Windows Xp – Click on start > Control Panel then click on the classic view on the left pane, select Network connectionon the control panel list.
- In Windows 7 – Click on start > Control Panel In the view by: on the upper right side of your control panel select large icon, then select Network and Sharing Center, on the left pane click on Change Adapter Settings and click on Local Area Connection
- In Windows 8 – Right click on Start and select control panel, In the view by: on the upper right side of control panel select large icon, Select Network and Sharing Center, on the left pane click on Change Adapter Settings and click on Ethernet.
Local Area Connection Configuration:
In the Local Area Connection status click on Properties, Inside the Local Area connection properties click on the networking tab and select Internet Protocol Version 4 (TCP/IPv4) and then click on Properties.
Under General Tab click on Use the following IP address check box to be able to change or add an IP address.
IP Address: The IP address you want to give to your machine the IP address should be the same across your network except for the last sigment.
Subnet Mask: Enter your network subnet mask here example of a subnet mask is 255.255.255.0 or by just clicking on the field, windows will automatically add the subnet mask depending on the I.P address you put on the IP address field.
Default Gateway: If you connect to the internet through a router the I.P address of the router must be entered here or if you use proxy server to connect to the internet input the IP address of your proxy server on this field, for a local area connection only you can leave this field blank.
Prefered DNS server: Usually same with default gateway if you connect to the internet through a router you can put the router I.P address or your network proxy server on this field or you can leave it blank if your network is for local area connection only.
