Internet v4 to run out of address next year

[milanchatterjee]

Hi All
The print version of The Times of India had published an article, which mentioned that the internet is to run out of address next year. The IPv4 will be then jammed and the IEEE is trying to popularize the use of IPv6 address. It also published the difference between IPv4 and IPv6, which we all know courtesy - Todd. There it mentioned that many companies are reluctant to use IPv6 but using the service of IPv4 and NAT.

So, which way the Networking industry is going? Any word Todd?

I could not find the article on the web version of the paper, otherwise I would have pasted the link here.

This has been going on for a long time. Whilst it will happen eventually (and in the not too distant future either) I know that for the last five years at least I've seen dire predictions that we'll run out "in the next year". And it's been on the cards for at least the last 10 years.

There is a considerable resistance to change (human nature I guess) and currently I'd reckon there's a dire shortage of folks who really have a handle on IPv6 (ka-ching!). I suspect we'll see IPv4 still run internally in businesses with protocol translation at necessary borders for some considerable time.

But definitely get learning it, it's gonna happen, and when it does IPv6 peeps will be in short supply (and will be suddenly driving more expensive cars).

Hi
So, we need to pay more attention to NAT and IPv6 course wares. I think, that initially NAT will be in demand and then professionals with sound knowledge of IPv6 will be in demand too.

There are a few policy suggestions pushing their way through the RIPE policy development process which discuss how the final remaining IPv4 addresses should be given to end users in the European region.
They all show that the effects of scarsity of IP addresses will be felt before the final few addresses become assigned to end users. All consumers of addresses will feel constrained, which means all businesses trading online, whether they are a traditional ISP, a growing e-commerce shop, or a datacentre/hosting firm. The policies under consideration are :

• 2008-06 - Both new and existing organisations requesting IPV4 addresses shall be given addresses only to support transitioning technologies (i.e. infrastructure services which enable access to IPv6 addressed resources.) They will only be given one block of IPv4 addresses, and this shall be the smallest possible range of addresses as decided by the community at large. This is the only range of addresses which shall be given to the end user, even if their needs justify more.
• 2009-03 - From summer 2010, any organisation shall only be given enough new addresses to cater for anticipated need for nine months. By summer 2011, this will change to three months. Organisations (registries and end users) MUST have used more than half of their address space within six months of assignment or allocation.
• 2009-04 - Organisations must demonstrate that they are implementing an IPv6 transition policy (RFC5211) in order to be given IPv4 addresses. Allocations from the RIPE NCC will be /27 (32 addresses for the entire registry, e.g. ISP)

This also means that the effects of black market trading in address space will be seen before the ‘anticipated’ IPv4 dry date in 2011. There are no magic bullets, you (and your customers, suppliers, and partners) need deep pockets, decades worth of existing resources, or an ipv6 transition plan. The only sensible option is to plan your v6 deployment today.

That's interesting stuff Big E, didn't know that - can only assume ARIN, APNIC et al are doing the same sort of thing. That certainly ups the pressure somewhat.

Oh and Milan - NAT (and PAT, aka NAT overload) are already in heavy heavy use and definitely need learning thoroughly (for the CCNA exam too). Not to be confused with NAT-PT which is protocol translation, one of the many tools that'll help with the transition to IPv6.

And I have no idea what happened to IPv1,2,3 and very little idea about IPv5
