Choosing to set up a static IP address is relevant when you want websites or devices to remember your IP. Static means that your IP address does not change, simplifying things like hosting and remote access.
Usually, users work with static or dynamic IP addresses for their devices. However, assigning a fixed IP address can ease many internal tasks of home networks. For instance, if you set up a static IP when hosting game servers, you won’t need to update the IP info.
What is a static IP address?
A static IP address is an Internet Protocol (IP) address that does not change. So, once you have assigned a static IP address, it will remain the same until further notice.
To set up a static IP, you will need to go through advanced settings and reserve them on your local network. The static IP address remains even if the device disconnects from the internet connection.
Configurations can allow tablets, routers, phones, laptops, or other devices like Raspberry Pi to have a static IP address.
Dynamic and static IP address differences
Here is a brief run-through of static vs. dynamic IP addresses:
- Each time a device goes online, it receives an IP address.
- The router assigns the next-in-line free IP address to the connecting device.
- Usually, IP will be dynamic, meaning it will change every time devices join the network.
- IP addresses can also expire, or, in other words, devices lose their dynamic IP addresses.
- If you set up a static IP, this cycle does not happen. Instead, the chosen device retains the IP as long as the network configurations persist.
- Sometimes, users might need to obtain an IP address from their Internet Service Provider (ISP).
DHCP and static IP addresses
DHCP reservation is a familial term. It means assigning a static IP at the router level. Essentially, you can assign a static IP through Windows network settings. However, it is also possible to do it through the router’s admin panel.
You will also need the MAC address of the device you wish to configure at the router level. An IP address identifies computers on the internet, and MAC addresses represent devices on networks.
Dynamic Host Configuration Protocol (DHCP) provides IP addresses and other networking settings to devices automatically.
How about dedicated IP addresses?
Static IP and dedicated IP addresses present the same concept: IP addresses that do not change. However, people use them in slightly different situations.
A dedicated IP address is a unique string assigned to a particular person or organization. In many contexts, people use static and dedicated addresses as synonyms.
When should you use a static IP address
It can be difficult to remember which device gets which IP address. The issue persists for many advanced networking tasks. Generally, you set a static IP address to prevent it from expiring.
- Static IP simplifies VPN or other remote access processes. Since the static IP address never changes, other devices will always know how to contact them.
- Fixed IP is useful for ensuring DNS servers work correctly. You won’t need to reconfigure DNS servers on routers or computers. However, dynamic DNS could also help to keep things running efficiently.
- People need static IPs if they are website or server hosts. While static IP is not a requirement for hosting web servers, it smoothens the setup and maintenance.
How to set up static IP addresses
Here are guidelines to set up a static IP for devices with different operating systems.
You should also remember the ranges of IP addresses:
- 10.0.0.0 through 10.255.255.255
- 172.16.0.0 through 172.31.255.255
- 192.168.0.0 through 192.168.255.255
You can set up static IP addresses directly through devices’ settings. However, it is also possible to achieve this via router settings. Many routers refer to static IP as DHCP reservation.
Essentially, your router will reserve your selected IP address for your chosen device. You will also need to provide the MAC address of the device.

Now, let's dive into the concept of a static IP address and related information.
What is a static IP address?
A static IP address is an Internet Protocol (IP) address that does not change. Once you have assigned a static IP address to a device, it will remain the same until further notice. This is in contrast to a dynamic IP address, which can change each time a device connects to the network.
Differences between dynamic and static IP addresses
Dynamic IP addresses are assigned by the router to devices each time they connect to the network. These addresses can change, and devices may lose their dynamic IP addresses over time. On the other hand, static IP addresses remain the same as long as the network configurations persist. This means that the chosen device retains the same IP address, simplifying tasks like hosting game servers or ensuring DNS servers work correctly.
When to use a static IP address
There are several situations where using a static IP address can be beneficial:
- Hosting game servers: Setting up a static IP address for game servers eliminates the need to update IP information each time the device connects to the network.
- VPN and remote access: Static IP addresses simplify VPN (Virtual Private Network) or other remote access processes, as other devices will always know how to contact them.
- Ensuring DNS server functionality: With a static IP address, you won't need to reconfigure DNS servers on routers or computers, ensuring their proper functioning.
- Website or server hosting: While not a requirement, using a static IP address can smoothen the setup and maintenance of web servers.
How to set up a static IP address
The process of setting up a static IP address varies depending on the operating system you are using. Here are some general guidelines for different operating systems:
- Windows: Open Settings, navigate to Network and internet, select your network, open Manage known networks, select Properties, and then IP settings. From there, you can edit the IP settings and enter the desired static IP address.
- macOS: Open System Preferences, go to the Network section, select the network you use, choose the Advanced option, click on TCP/IP, and select Manual. Enter the necessary information, such as the static IP address and subnet mask, and save the settings.
- Android: Open Settings, tap on Network & Internet, open Wi-Fi, select the network you are connected to, tap on the pencil icon to open network settings, navigate to IP settings, replace DHCP with Static, and fill in the necessary information. Save the settings.
- iOS: Open Settings, go to Wi-Fi, tap on the information icon next to the network name, open the Static section, enter the desired static IP address, and provide other necessary information. Save the settings.
- Ubuntu: Click on the top right network icon, open Wired Settings, click the settings icon to enter the configuration, open the IPv4 section, mark Manual, and fill out the necessary information like IP address, netmask, default gateway, etc. Apply the settings to assign the static IP address.
Remember to refer to the specific documentation or support resources for your operating system for more detailed instructions.
