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.

Static IP vs. dynamic IP addresses

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:

  • pros
    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.
  • pros
    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.
  • pros
    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.
  • pros
    Geolocation stability. A static IP helps to ensure that services and websites always have the correct approximate location information based on IP.
  • pros
    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:

  • cons
    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.
  • cons
    Costly. Static addresses usually cost more for ISPs and consumers than dynamic IP addresses.
  • cons
    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.
  • cons
    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.

  • pros
    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.
  • pros
    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.
  • pros
    Better availability. Dynamic IPs are reusable, meaning your device receives an existing identification number as needed.
  • pros
    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:

  • cons
    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.
  • cons
    Limited remote access. Finding your device with a dynamic IP may be challenging for remote access tools, which may impact your work efficiency.
  • cons
    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:

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:


  1. Click on the taskbar search and type “Command prompt.”
  2. Hit “Command prompt.”
  3. Type “ipconfig/all” and press “Enter.”
  4. Find the “DHCP enabled” line. “Yes” means your IP address is dynamic, and “No” means your IP is static.


  1. Click on the Apple icon and hit “System settings.”
  2. Choose “Network” and click “Wi-Fi.”
  3. Then click “Details” next to your network.
  4. Click on “TCP/IP.”
  5. Find “Configure IPv4.” “Manually” means your IP address is static, and “Using DHCP” means your IP is dynamic.


  1. Head to “Settings.”
  2. Tap “Connections” and then hit “Wi-Fi.”
  3. Tap the gear icon next to your active network.
  4. Hit “View more.”


  1. Turn on “Settings.”
  2. Tap on “Wi-Fi.”
  3. Choose your currently active network.
  4. Find “Configure IP.” “Manual” means your IP address is static, and “Automatic” means your IP is dynamic.
