The main difference between static and dynamic IP addresses is that static IP addresses remain the same, while dynamic IP addresses change each time a device connects to the internet: 

• Static IP addresses

  Manually configured and assigned to a device, static IP addresses don't change unless manually reconfigured. They are often used for hosting servers and remote access.

• Dynamic IP addresses

  Automatically assigned by a network's Dynamic Host Configuration Protocol (DHCP) server, dynamic IP addresses change over time. They are commonly used in residential and business devices for standard devices.

​

Here are some other differences between static and dynamic IP addresses:

• Cost: Static IP addresses are more expensive than dynamic IP addresses. 

• Maintenance: Static IP addresses require more maintenance because the IP address needs to be manually reconfigured if a device is moved to a different network. 

• Availability: A static IP address can only be assigned to one computer at a time. 

• Security: Dynamic IP addresses make it harder for attackers to target networked equipment. 

• Hosting: Dynamic IP addresses are less effective for hosting servers and websites. 

• Geolocation: Dynamic IP addresses can make geolocation data inaccurate. 

• Remote access: Dynamic IP addresses can make it difficult to access the internet from devices outside a primary network.
