Static IP vs. dynamic IP addresses
Understanding the complexities of different types of IPs is essential so you can effectively manage your business or home network. Whether setting up a business server or managing a home network, dynamic and static IP addresses affect your online experience differently.

What’s the difference between static and dynamic IP addresses?
While a static IP address is a permanent and unchanging IP assigned to a network, a dynamic IP address changes every time a device is connected to the network. Internet service providers (ISPs) typically assign dynamic IP addresses, a more practical option for you and the ISP. However, if you want a static IP, you must request it when ordering an internet service. We’ll explain the rest of the main differences between static and dynamic IPs.
Advantages of a static IP address
For some business applications and networking setups, static IP addresses offer the following benefits:
- Consistent network identity. A static IP address provides a device with a constant and unchanging network identification. It helps to ensure that devices can always access services like website and email server hosting and FTP.
- Convenient remote access. A static IP address enables a reliable connection with a particular network device for remote access applications like security cameras and remote desktop programs. Such functionality benefits companies where employees must access corporate resources from a distance to perform daily tasks.
- Smooth server hosting and DNS management. A never-changing static IP can help ensure the continuous and reliable operation of services and reduce waiting times for the end user.
- Geolocation stability. A static IP helps to ensure that services and websites always have the correct approximate location information based on IP.
- Improved network reliability. A static IP doesn’t need to handle IP changes, which leads to a stable and reliable internet connection.
Disadvantages of a static IP address
While a static IP address might be helpful in certain situations, it has some drawbacks:
- Security concerns. If your IP address doesn’t change and you use a static IP address, a malicious actor can carry out DDoS attacks on your system if they find out your IP address.
- Costly. Static addresses usually cost more for ISPs and consumers than dynamic IP addresses.
- Limited availability. Static IP addresses are a finite resource and, once dedicated to a user, can’t be reused or reassigned to other consumers until the assignment is revoked.
- Requires extra management. Static addresses require more maintenance because each static IP has to be assigned and managed uniquely to prevent IP conflicts or overlaps.
Advantages of a dynamic IP address
Dynamic addresses have a bunch of advantages, particularly relevant to individual users.
- Simple configuration. A dynamic IP address doesn’t require administration because the Dynamic Host Configuration Protocol (DHCP) server assigns the IP addresses to the device and handles the IP distribution process.
- Low maintenance costs. A dynamic IP is a default IP that ISPs assign to your device every time you connect to the internet, so there’s no extra fee.
- Better availability. Dynamic IPs are reusable, meaning your device receives an existing identification number as needed.
- Enhanced privacy. A dynamic IP address is less prone to hacking because it is harder for bad actors to target your network with a changing identification number.
Disadvantages of a dynamic IP address
However, a dynamic IP may not always be the best option:
- Inconsistency for hosting. While a dynamic IP address is incompatible with DNS, it might not be the best option for hosting websites, email servers, or services requiring a steady access point. However, you can use dynamic DNS servers, but they require extra technical knowledge and expenses.
- Limited remote access. Finding your device with a dynamic IP may be challenging for remote access tools, which may impact your work efficiency.
- Potentially slower. Constant hunting for a new IP address can slow down your internet experience. While it is usually not an issue for an individual user, such a process can disrupt the operation of websites and applications.
What is a static IP used for?
Static IPs are used in situations where an unchanging IP is required. Here are some examples:
- Establishing a file server at home.
- Integrating a second router into an existing network.
- Remote printing.
- Accessing your IP cameras remotely.
- Port forwarding.
How to check if you have a static or dynamic IP address
Follow these instructions to check if your IP address is static or dynamic on different devices:
Windows
- Click on the taskbar search and type “Command prompt.”
- Hit “Command prompt.”
- Type “ipconfig/all” and press “Enter.”
- Find the “DHCP enabled” line. “Yes” means your IP address is dynamic, and “No” means your IP is static.
MacOS
- Click on the Apple icon and hit “System settings.”
- Choose “Network” and click “Wi-Fi.”
- Then click “Details” next to your network.
- Click on “TCP/IP.”
- Find “Configure IPv4.” “Manually” means your IP address is static, and “Using DHCP” means your IP is dynamic.
Android
- Head to “Settings.”
- Tap “Connections” and then hit “Wi-Fi.”
- Tap the gear icon next to your active network.
- Hit “View more.”
iOS
- Turn on “Settings.”
- Tap on “Wi-Fi.”
- Choose your currently active network.
- Find “Configure IP.” “Manual” means your IP address is static, and “Automatic” means your IP is dynamic.
