Hello pma111,

It is mainly because most companies have webservers, fileservers, citrixservers etc. wich they have to be able to access at anytime 24/7. Then you can't have a server changing IP all of a sudden.

dynamically usually change every time you reboot, i don't know if i can explain it right, but i'll try on why they change regularly:

- A ISP has a range of dynamically IP adresses that they can use for there costumers.
- When you turn on your computer and boot into windows etc., then you get an IP from your ISP, unless you have a static IP.
- But when you restart or close your computer, the IP you had will be released so someone else will be able to use it, and thats why you get a new one every time you restart, and why dynamically IP's change.

Servers are build to run 24/7, thats one reason why it runs all the time.
Servers takes a long time to start up, so it would be waste of time, and manpower to have to start 1 or more servers up every day.
Some people in the company might need access to the server at night or early in the morning, when no one is at the office.
Allso, if the servers run 24/7, then it is possible to troubleshoot errors without being at the office.

Their is alot reasons for this, but is some of the most reasonable.

Hope this can help you, and answer your questions.

The IP that ipconfig shows, is the IP you have locally in your own network at home. The IP you get from your ISP is the IP you will have when you go on the Internet.

Try and go to www.myip.dk, that is the IP you get from your ISP.
