What Is an IP Address?
An IP address is a 32-bit decimal number that is always accompanied with its corresponding subnet mask, which is also a 32-bit decimal number. Both IP address and subnet mask are divided into 4 octets, and each octet is separated by a dot (.) a.k.a. period. In the network, where multiple computers are connected to each other, each computer must have a unique IP address and a common subnet mask in order to communicate with other computers in the network.
An example of an IP address and its subnet mask can be:
IP Address 192.168.0.1
Subnet Mask 255.255.255.0
IP Address Assignment Methods
A computer can be assigned with an IP address in two different ways:
- Dynamic IP Address – When a computer is configured to get an IP address automatically from the DHCP server in the network, the address along with its corresponding subnet mask that is automatically assigned to the computer is called a dynamic IP address.
- Static IP Address – When a network is small, and no DHCP server is present in the network, administrators manually assign an IP address to each computer. The IP address along with its corresponding subnet mask that is manually assigned to a computer is called a static IP address.
What Is DNS Server?
A DNS server is a computer that stores the names of the computers along with their corresponding IP addresses that are present in the network. With the help of DNS server, communication between the computers in the network becomes easier, and communication between a computer and the Internet becomes possible.
What Is DNS Address?
Since a DNS server is also a dedicated computer, it has its own unique IP address. A DNS address is the IP address of the DNS server. In organizations, administrators install and configure a dedicated DNS server for easy communication. In such scenarios, IP address of the DNS server is used as a DNS address for client computers.
On the other hand, when users subscribe for an Internet connection at homes, the Internet modem that the ISPs provide also works as a DNS server. In such cases IP address of the Internet modem becomes the DNS address for home computers.
How to Assign Static IP and DNS Address?
To assign a static IP and DNS address to a Windows 8 computer, steps below must be followed:
- Use the administrator account credentials to log on to Windows 8 computer, to which static IP and DNS address is to be assigned.
- Click Desktop tile from the Start screen to go to the desktop.
- Once on the desktop screen, hover mouse to the bottom right corner of the window.
- From the displayed options in the right, click Settings.
- Click Control Panel from the Settings pane.

- From the right pane of Network and Internet window, click Network and Sharing Center category.
- From the left pane of Network and Sharing Center window, click Change adapter settings.
- On Network Connections window, right-click the network adapter on which static IP and DNS address is to be configured.
- From the context menu that appears, click Properties.
- On network adapter’s properties box, double-click Internet Protocol Version 4 (TCP/IPv4) from This connection uses the following items list.
- On Internet Protocol Version 4 (TCP/IPv4) Properties box, click to select Use the following IP address radio button.
- Once selected, specify the static IP and the subnet mask in the enabled IP address and Subnet mask fields respectively.
- In Preferred DNS server field, type the DNS address that is to be provided to the computer.
- Once done, click OK to save the modified settings.
- Back on network adapter’s properties box, click OK.
