What is the difference between static and dynamic IP ?

Static IP	Dynamic IP
Static IP configured by the ISP (Internet Service Provider)	Dynamic IP configured using DHCP (Dynamic Host Configuration Protocol) .
The static IP is fixed which means it could not be changed until the user wants to change it.	Dynamic IP changes each time when a user connects to a network.
The associated risk of website hacking is large in static IP because it is always constant.	There is low risk regarding dynamic IP.
When the device is configured with static IP address, it can be tracked.	In case of dynamic IP address the tracking of the device is difficult as the IP address is always changing.
Expensive than dynamic IP	Cheaper than static IP
Use DNS to map domain name to IP address, and use domain name to address the static IP address.	Use Dynamic DNS for dynamic IP address, but it’s not as clean as the static IP address.
