Running out of IPV4 Adresses
Jarudin:
Vint said sorry.
In any case, don't worry about IPv6, when it's time to change for sure, you'll know.

Why?
In my experience, dynamic IPs are worse for P2P. When I had DSL and dynamic IP, if my router lost the PPPoE connection and reconnected, it got a new IP and torrents would not work until uT connected to the tracker and updated the IP. Later when I got static IP this was eliminated.

If you have a static IP you are you, if they log torrents for an entire year and you have the same IP during that time they need to identify you for one IP. If you have a dynamic and change once every week then they get the information for one week. Unless the ISP logs all of your IPs during that entire time, which costs money.
It is bad since it basically gives away information that can be used to track you.

IIRC the law says that the ISP has to keep DHCP logs for some time. (click to show/hide)In 15 March 2006 the European Union formally adopted Directive 2006/24/EC, on "the retention of data generated or processed in connection with the provision of publicly available electronic communications services or of public communications networks and amending Directive 2002/58/EC".[1][2] The Directive requires Member States to ensure that communications providers must retain, for a period of between 6 months and 2 years, necessary data as specified in the Directive
* to trace and identify the source of a communication;
* to trace and identify the destination of a communication;
* to identify the date, time and duration of a communication;
* to identify the type of communication;
* to identify the communication device;
* to identify the location of mobile communication equipment.
The data is required to be available to competent national authorities in specific cases, "for the purpose of the investigation, detection and prosecution of serious crime, as defined by each Member State in its national law". And it still can be used for tracking across IPs, depending on the software used (for example I don't update uT and don't change the port). If you want better protection against this, use a VPN service, like Ipredator.
And a dynamic IP usually does not change very frequently, well, depending on the reliability of the connection.
I actually have a semi-static IP now. I can change it if I change the MAC address (and wait 5 minutes) or (IIRC) pull out the cable and wait a few hours. The IP stays the same if there is only a minor interruption or I reboot my router.

If someone is worried about being tracked that much they should think about using a VPN or similar services.

**a little off topic**
This IPv6 thing was design duringed the 1990s right?
One could argue that it is totally incompatible with the mobile era. Why? Because the address is still relative to some fixed location (router/dhcp server etc).
It doesn't matter whether you have an IPv6 address genuinely unique throughout the universe. You will have your ip address eventually changing between different wifi hotspots/infrastructures while you are on the move, causing connectivity/security issues making it the responsibility of the content provider.
Pentium100:
Well, making the IP address fixed to the person or the device across ISPs would make the routing tables huge. Also, unless you are changing ISPs in the middle of a connection it is no problem. If I connect with my cell phone to the internet, the IP stays the same when I move from tower to tower. Making the IP stay constant between ISPs would require cooperation from all ISPs and those who run the hotspots. It also would allow spoofing.
