Dynamic IP Address vs Static IP Address

Computers use IP addresses to locate and talk to each other on the Internet. It is the unique identifier of a computer on the net.

A dynamic IP is an address that is assigned your computer temporarily by ISP when you connect to the internet.Static Dynamic IP Address

For the duration of you connected it will remain the same IP address but when you disconnect and reconnect you will probably be given a new (different) IP address. The IP address you had before will be given to someone else.

A static IP address is an IP address that is assigned to you computer by an Internet service provider (ISP) to be its permanent address on the Internet. Every time you’re connected the same IP address will be assigned.

If you need to make your dynamic IP address into static IP probably you have to contact your ISP (Internet service provider) and ask them for assign you a static IP. So you can have an IP address permanently assigned to you which you can use every time you are connected.

Making your IP address static cannot done yourself because an IP address needs to be globally unique, you can't just pick one for yourself as you desire. It needs to be assigned to you by your ISP.

  • Advantages of having Dynamic IP:
1. If you have a hole in your firewall and a dynamic IP, then every time you disconnect and reconnect any hacker who found you by your IP address on the first visit, will much more difficult to find you again because your address will be different.

2. Fixing IP bans from Forums, chartrooms and etc.

3. Override Time limitations which are depend on the IP address (I.e. Rapidshare).

  • Advantages of having Static IP:
The only reason I know why you would need a static IP is if you want other users to be able to connect to your computer through internet. (I.e: Web server)
