Title should've been 'addressess' - sorry.

The internet is suuposed to be a universally avialibale 'thing' (for want of a better word, and for every computer on the internet there is an IP address, right?

But with the expanding computer market and people having numerous computers (i.e. A PC, a Laptop and a Work Station - just for them) we're going to need billions of IP's, are there really that many? Or are we going to run out sometime soon?

S'pose they'll just increase the number of numbers in an IP address...

no, they HAVE run out of ip addresses, so they created new and more complex ones. I think there is an almost infinite supply now

The majority of Internet users surf via a proxy, so only that proxy needs an 'official' IP address, while everyone using it will have one of the reserved IP addresses (eg 192.168.0.1).

Even so, the number of machines directly connected to the net is increasing rapidly. Yes we will run out sometime.

There is a newer IP standard (called IPv6) that will use 128 bits for the address, instead of the 32 bits used for IPv4. That should keep us going for a few millenia

there are 4,228,250,625 possible with the current IPv4 which is only for those computers actually connected to the internet;
remember only static ip users need these...

most isp and or host actually give you a static ip which is routed through thier own ip.
same goes for dynamic ip's ... which means there are 4billion each isp can have for thier customers routed through a single ip.

then you have the static hosts (T1/T3/etc) but again, most of these are websites on a host routed through a single IP or are a College/Uni again routed through a single IP.

IPv6 however allows for something around 72,057,594,037,927,936 possible IP address'.

anyway you look at it, doesn't really consern us as the in-charge of keeping the internet ticking over won't allow it to actually reach it's maximum... they'll always invent a higher address space.

The difficulty will be getting people to upgrade to IPv6, although as windows users, that won't be a problem for us as long as our ISPs upgrade too.

Well IVv6 is already in linux and Windows 2k3 server... i think its going to be in Longhorn and there will probably be a IPv6 update for XP soon enough....
if there isnt one now


i just hope you dont have to use IPv6 on lan cause that will be a pain in the behind

doubt it seems logical to keep the easy IP's for LAN's and the like and IPv6 for outside.

raven meantioned always invented a higher address space, but then the strange imagination of me will make these things solid, so they fill the world with cheese cake

or not

Windows XP has IPv6 already (iirc so does Windows 2000)
the IP address' aren't that far different from what we use now.

it still uses the xxx.xxx.xxx.xxx:port structure
the only difference is rather than,

8bit x 4 IP : 16bit Port it is a 32bit x 4 IP : 16bit Port

to cover this it changes from numberical to alpha numerical (like a metric address)

something like FFF.FFF.FFF.FFF:port ... but that might be a 64bit one i can't remember.

Gonna be tough on the millions of routers that don't understand IPv6.

I think they should've thought it out a bit more when they first came up with the ip addressing system. They should've considered the fact that the internet would grow so much, and use IPv6 in the beginning.

They didn't really think about how popular the internet would be. Same goes for security.

still a pity about the routers. Most Cisco routers can adapt to IPv6, but some of the old ones can't. Looks like IPv6 may be a tad costly for some people.


P.S. Just wondering, has anyone here got a Cisco qualification? I'm 3 quarters of the way through a CCNA.

one question, does the isp's have to use ipv6 for local network at all? So could you basically link ipv4 network to ipv6 through a modern router? This way only the international traffic lines would have to be changed, and local changes be made only if the isp's run out of ip's.
