What are the differences between static and dynamic IP addresses?

Static IP addresses are fixed, while dynamic IP addresses change each time a device connects to the internet.

A static IP address, as the name suggests, is a permanent Internet Protocol (IP) address that remains constant and unchanging over time. It is manually assigned to a device and remains fixed until the user changes it. This type of IP address is typically used for hosting websites, providing email or FTP services, or for any application where a constant IP address is necessary. However, static IP addresses can pose a security risk as they are easier to track for data mining purposes. They are also less cost-effective as they require more management and maintenance.

On the other hand, a dynamic IP address is assigned automatically by the network every time a device connects to the internet and changes over time. This is done through a method known as Dynamic Host Configuration Protocol (DHCP). Dynamic IP addresses are more cost-effective and offer better privacy as the changing IP makes it harder for cybercriminals to track the device. However, they are not suitable for hosting websites or services that require a constant IP address.

In summary, the main difference between static and dynamic IP addresses lies in their stability and use. Static IP addresses are fixed and suitable for hosting services, but they require more management and pose a higher security risk. Dynamic IP addresses, on the other hand, change with each connection, offering better privacy and cost-effectiveness, but are unsuitable for services that require a constant IP address.
