idea for ipv6 allocation scheme

[Ilja.Maslov@nokia.com]

Hi,

Wanted to touch mobile devices a bit.

In current GPRS implementation, the addresses (IPv4 or IPv6) are assigned by
GGSN (gateway out of the GPRS backbone towards the content).

This means, that even if you're roaming in a foreign country, you still get
the address of your very own operator.  Things are supposed to be changed a
bit in 3G All-IP networks, but I do not remember any discussions on address
assignment by Base Station Controller.
Furthermore, it will make hand-overs to the next cell a nightmare (imagine
changing your IP every time you change your BTS).

Best,
Ilja

: whole purpose

: don't care
: what the MAN does. I think the MAN might even like the idea 
: enough to foot

: 
: Good points. But I kind of like the idea of eliminating DNS 
: in at least
: one addressing scheme. The ISP sharing thing would be a big 
: problem, I was
: thinking however of a separate infrastructure, either 
: government-funded or
: grassroots-initiative.
: 
: I'd still give a byte up for the planet code, for the 'cool' factor if
: nothing else.

: 
: Another inveterate hacker. You _could_, but you wouldn't need 
: to, because
: you can also get addresses by other methods.

: 
: Didn't forget that at all. This is not about J. Random 
: Hacker, it's about
: normal people (the kind that don't subscribe to lists like this).
: 
: And who says we have to play by the rules, anyway? Even if I 
: agree on the
: last 64 bits being private, who says I can't subnet those out even to
: /128s? And yes, in many cases, with a good compression 
: scheme, I could get
: the above into 8 bytes. 2 for the TLA, 1 planet, 1 country, 1
: state/province/prefecture etc., 1 city; makes 6. For a small town with
: less than 65,000-some-odd addresses that would work.

: 
: I'm something of a conspiricist myself, but I think speading

: 
: You move, you change addresses. That's the point. And if the
: infrastructure is laid out well, the impact on routers will 
: be minimal.
:  
: IPv8 would be great, but I was hoping to do something before

: 
: Zipcodes would work great in the US, since the USPS already 
: does all the
: work of mapping out new addresses to delivery-walk 11-digit codes. An
: 11-digit decimal number will fit easily into 5 bytes, leaving 
: room for the
: TLD and country code. I may have to drop the planet code after all...
