Stability vs. Flexibility: Comparing Static And Dynamic IPs

Internet Protocol (IP) addresses are unique numbers identifying network devices. They work like home addresses, allowing computers and devices to communicate. 

Over 4 billion IPv4 addresses and over 340 undecillion IPv6 addresses are available worldwide. These IP addresses are further classified into two types: static and dynamic.

A static IP address is constant, while a dynamic IP address changes periodically. Static IPs are assigned by Internet Service Providers (ISPs), while the latter is given by Dynamic Host Configuration Protocol (DHCP) servers. 

Both types are distinct in a lot of ways. Continue reading to learn more about the differences between static and dynamic IP addresses.

Static vs. Dynamic IP Address

There are four main types of IP addresses, which include static and dynamic IP addresses. A static IP address is an unchangeable identifier assigned to devices, ensuring a constant connection. It's vital for web servers and businesses needing a reliable international identity.

A static IP address is used for these situations:

• Handling numerous connections simultaneously
• Maintaining easy and uninterrupted access
• Ensuring reliability for external devices and networks

Meanwhile, a dynamic IP address is not tied to individual users or companies. ISPs assign them as needed. 

Dynamic IPs are commonly used for consumer devices on home networks. This type of IP address may not be the best choice for businesses that prefer a fixed IP address.

A dynamic IP address is used for the following:

• Regular devices and routers at home
• Maintaining online access when switching networks
• Managing the limited quantity of unique IPs

Pros And Cons Of Using Static IPs

A static IP address has its own set of benefits and drawbacks. Here are the advantages and disadvantages of static IPs:

Advantages And Disadvantages Of Getting Dynamic IPs

Dynamic IP addresses also come with pros and cons of their own. Here’s a table presenting their benefits and drawbacks:

How To Change Your IP From Static To Dynamic?

Dynamic IPs are more practical than static ones if you're looking for affordable options. Fortunately, there are ways to change your IP from static to dynamic. 

Check out four methods you can easily follow below: 

1. Changing Your IP Through Settings

To set up a network adapter to ask for a DHCP setup instead of a static IP address through Settings, follow these instructions:

1. Open Settings.
2. Tap on Network & Internet.
3. Click on Ethernet or Wi-Fi.
4. Tap on the network connection you want to configure.

5. Look for the IP settings section and click the Edit button.
6. Choose the Automatic (DHCP) option in the Edit IP settings menu.

7. Click the Save button.

Once you’ve completed these steps, the configuration of your network system will be reset.

2. IP Switching Via Command Prompt

Using your device's command prompt, You can switch from a static to a dynamic IP setup. Here are the steps:

1. Open the Start menu.
2. Look up “Command Prompt” and right-click on the first search result. Choose the “Run as administrator” option.

3. Enter the following command to identify the network adapter’s name. Press Enter.

It should give you the output below. The one in the red box is your network adapter’s name.

4. Key in the command below to set the network adapter to obtain its IP configuration using DHCP. Press Enter.

Replace “Ethernet” with the actual name of the adapter you wish to configure.

Once you’ve completed these steps, the network adapter will stop using a static IP address. It will automatically obtain its configuration from the DHCP server.

3. Transforming Your Static IP To Dynamic Via Powershell

Switching from a static IP to a dynamic setup is possible with Windows PowerShell. All you have to do is follow the steps below:

1. Open the Start menu.
2. Search for “PowerShell.” Right-click on the top result and select “Run as administrator.”

Key in the command below and press Enter to determine the “InterfaceIndex” number associated with the network adapter:

It should give you this output:

4. To allow the network adapter to obtain its IP configuration through DHCP, use the following command and press Enter:

Replace “Ethernet” with the actual name of the adapter you wish to configure.

5. Enter this command to enable the network adapter to obtain its DNS configuration through DHCP:

Replace “15” with the appropriate Interface Index for your desired adapter.

Once you have completed the steps, the adapter’s IP and DNS addresses will be reset. Your computer will obtain a new dynamic configuration from DHCP.

4. Using The Control Panel To Change IPs

To set up a network adapter to use a dynamic IP address through the Control Panel, follow these simple instructions:

1. Open Control Panel.
2. Click on Network and Internet.
3. Tap the Network and Sharing Center.
4. On the left side, click the link “Change adapter settings.”
5. Right-click on the network adapter, then choose Properties.
6. Select Internal Protocol Version 4 (TCP/IPv4).

7. Click Properties.
8. Select “Obtain an IP address automatically” and “Obtain DNS server address automatically.”
9. Tap OK.

After you complete these steps, the IP configuration that was manually set will be removed. The device will automatically get a dynamic IP address from the network.

Conclusion

Understanding the difference between static and dynamic IP addresses is essential for navigating the digital world.

Static IPs are consistent and ideal for certain websites, businesses, or applications. Dynamic IPs offer flexibility and cost-effectiveness for most users. Choose the correct type of IP address according to your needs and preferences.
