Running out of IPV4 Adresses

[tomoya-kun]

Is that really as bad as it sounds or is it exaggerated?


IPv4 Space Shrinks To 5% – Final Addresses To Be Issued In Early 2011

I think they say ipv4 supports a max of like 100 million addresses? ipv6 is like... way more.

[dogsinafen]

They knew IPv4 was going to run out of address in the near future. Hence, they've been limiting who get's to have a block of IPs.

IPv6 will provide a retarded amount of IP's so there would be no worry of running out anytime soon. Hopefully when people start switching over Canadian ISPs don't break (rogers ) since some of them are not prepared.

An IPv4 address is 32 bits while an IPv6 address is 128 bits.

something like waaaaaaaaayyyyyyyyy y more actually.

You could literally assign an ip to every "ant" on this good earth   Finally they can also ping each other ...


@tomoya-kun: prepare for the next topic ... Running out of MAC Addresses...   

[Freedom Kira]

Funny because I'm sitting in class right now and the prof just talked about this like 3 min ago...

But yeah, 32 bit to 128 bit is a huge jump. Think of it this way - every bit doubles the number of addresses you can use, starting from 1 at 0 bits. Just jumping from 32 bits to 33 bits should last at least a couple years, but seeing today's growth, maybe less.

would like to add:
All p2p users should be pro-ipv6.
The current solution to share ip addresses is limited - with nat, p2p breaks if few or nobody has an ip address that can listen on user defined ports.
 Else there would be no way to connect to each other...

[Pentium100]

I'm a P2P user and I'll wait until others jump to v6 before I do. Then I'll be able to do it easier (also, how do I get IPv6 on an old computer with Windows 98 or NT4? xp and 2003 support it so here it shouldn't be a problem).

[sanguis]

IPv4 = 2^32 = 4,294,967,296

IPv6 = 2^128 = 340,282,366,920,938,000,000,000,000,000,000,000,000

So a lot more connections; there's talk of giving individual light-bulbs IP addresses so they can all be controlled by your brand new Smart Home Computer.

[tomoya-kun]

Wow, my ISP doesn't even support IPV6 fully.

Unless you need your light bulb to directly connect to the internet, even IPv4 is beyond overkill for this kind of purpose.

But there are experimental drinking glasses that connect to the internet and when you and your SO are really far apart and drink from the glass, it lights up. So when glasses are used to connect to the internet then there will also probably be some use for a light bulb to connect to the internet.
For example when you are listening to music you'll want some flashy light show. No problem, just press the DISCO MODE button on you light bulb and it'll connect to your computer and flash on and off on your music. And thus no need of buying expensive disco lighting anymore.

I heard the opposite. I read somewhere that IPv6 will have anti P2P protocols.

Dynamic IPs are good for p2p, something they can easily stop using in IPv6.

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.

[Jarudin]

Vint said sorry.

In any case, don't worry about IPv6, when it's time to change for sure, you'll know.

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.
