Static IP vs Dynamic IP Relating to Devices

What is the difference between a static IP address vs dynamic IP address? When a device assigned a static IP address, the address does not change. When a device assigned a dynamic IP address it is exactly that, dynamic.  It could change frequently, or not change for more than 1 year. It really depends on how the DHCP server that’s assigns the IPs is set up.  To clarify, most devices use dynamic IP addresses.

Businesses that host their own website and/or internet services, a static IP address is the best option.  They even have the advantage when remote workers log into work via VPN.  Consumers are usually fine with dynamic IP addresses.

So, the question is obvious for what a person should use a static IP address vs dynamic IP address?  There are advantages and disadvantages of both a static IP address and dynamic IP address.

Some advantages of a static IP address!  Faster internet speed, easy remote access, communication is usually hassle free, and the ability for simple server hosting.  On the other side the disadvantages of static IP address!  Mainly the cost can be expensive, difficult and complex setup, and can be known for lack of security.

Some advantages of a dynamic IP address!  Cost of price associated with the ISP and usually lower, since associated with ISP it is an automated configuration. On the other side the disadvantages of dynamic IP address!  Since it depends on the ISP there is the issue of more downtime and also the inability for remote access capabilities.

Find the “DHCP Enabled” text and if NO you have a static IP address and if YES you have a dynamic IP address.

With a Mac computer:
Under system preferences, select Network and then “Advanced”, then go to TCP/IP. Under “Configure IPv4” if you see MANUALLY you have a static IP address and if you see USING DHCP you have a dynamic IP address.

In conclusion
