Static IP Address vs. Dynamic IP Address — What's the Difference?
By Tayyaba Rehman — Published on January 17, 2024
Static IP Address is a permanent and fixed internet address for a device. Dynamic IP Address is a temporarily assigned IP, changing with each network connection.

Key Differences
Static IP Address is a constant internet address assigned to a device, remaining unchanged over time. It allows reliable and consistent remote access to the device. Dynamic IP Address is assigned by a network when a device connects and can change each time the device connects to the network. This offers flexibility and efficient IP address management.
In terms of stability, Static IP Addresses provide a stable, unchanging point of contact for devices, making them ideal for servers or devices hosting websites. Dynamic IP Addresses, by contrast, may change frequently, which can disrupt direct remote access but is suitable for consumer devices that don't require constant direct access.
For security, Static IP Addresses can be more vulnerable to hacking attempts, as the address remains the same. Dynamic IP Addresses offer more security through their changing nature, making it harder for unwanted access. However, this can complicate certain network configurations.
From a management perspective, Static IP Addresses require manual configuration and are limited in number, which can lead to shortages. Dynamic IP Addresses are managed automatically by the DHCP (Dynamic Host Configuration Protocol), making them easier to administer for large networks.
Static IP Addresses are typically used in business environments where external access to specific devices is necessary. Dynamic IP Addresses are common in residential and small business settings, where a constantly assigned IP address is not essential.
