That depends... take, for example, a situation where someone threatens someone's life on a forum. Normally those moderating the forum in question would see that, report it to their local ISP, that ISP would know who used/had that IP addressed at the time of the post, know who's account that is, and take proper action.
In this case, one finds the ISP, finds out which account/home address used that IP address at that time, contact the police in that area, they look into their active cases, find the guy who's currently being charged/investigated for said crime, match this admission to the information in the case they're investigating, plus his address matching the address of the IP address used, and that could be considered credible evidence against said person.
There are many legal cases that use information/posts from emails, myspace, facebook, forums, etc. in court cases, which are obtained through IP Addresses, which most ISP's keep track of.
Secondly, I highly doubt the cops would subpoena both his ISP & Andem's server in Germany over a suspected DUI.
They don't have to.
As said before, someone in here, or even a mod who is inclined to do so, can get the IP info. Mods can get the IP info through their tools running the forum, and regular members can get a hold of various programs that can gather IP information as well.
There are also plenty of web sites online that you can enter an IP address into which will in turn, tell you where that IP address is located, what company owns that IP address, and the location right down to the town/city where that IP address was used.
As an example:
What Is My IP Address? Lookup IP, Hide IP, Change IP, Trace IP and more... (external - login to view)
^ Click on there and it'll tell you your IP Address, what ISP owns that IP, the account that used it and show you on a map where you are.
Got me down pretty good.
Getting IP information isn't that hard.
