People may think that the Dynamic IP address is more secure than the Static, as it changes with each session on the network and it becomes difficult for the hackers to find the computer. In contrast, a static IP address can become a security risk, because here the address is always the same and it is easier to track the computer for data mining purposes or someone who is really determined to find your computer and cause damage to it has a better chance of doing so or has more time to work on getting past your security. But, according to me, the type of IP address assigned has nothing to do with the security of the computer when you have a good security program or a firewall installed on it.

 

You're not an Internet expert and you got a static ip?
Dude, are you high?

You got a static ip for 3 reasons maybe.
First your ISp gave you one (very rarely) and you was like "cool I got a static ip".
Second, you got a static ip because you want to learn stuff and you have no idea so you wanna learn as you go along. Ok cool ... Which ties into the third point.
Third, you got money to burn so you're paying twice as much as everybody else for Internet service.
