Why the slow adoption of IPv6?

[FN-GM]

Hiya,

 

Why is it the adoption on IPv6 is slow? We are so tight on public IP's you would think it would be in full swing by now. Big companies who use lots of IP's would benefits all of us if they used IPv6.

 

Internal networks, we don't need it. But for the internet we do!

 

Just wondering what the hold up is?

 

Cheers

They want to wait until the last possible minute to do so. However, I believe Facebook, Google and MS servers have started to make the switchover, along with the iCloud servers as well.

But why wait? surely doing tricks like that will cause headaches down the line?

They need to do the adoption slowly but surely, I am certain once the bigger companies are done, the rest will follow. GoDaddy are also starting to move servers, but it isn't as easy as just inputting numbers, webhosts have to literally do hundreds of thousands of DNS updates etc etc as well. It is a long process

It costs money.

 

I think there are still quite a lot of software and hardware related issues. Facebook mention a few in a recent presentation they did.

Google and Facebook have been accessible via IPv6 for years.

 

Google's IPv6 adoption stats are interesting. Worldwide, only 4.19% of users access Google via IPv6 and in the UK, it's just 0.16%. :eek:

Internal networks wouldn't be IPv6 surely? They would remain IPv4 and then NAT out to an IPv6 address? That surely would limit the amount of hardware and applications that do not have IPv6 support.

In "their" "ideal world" it would all be IPv6. It'll never catch on though, especially for corporate/enterprise setups, it's too much of a headache.

I have been prepping for ip6 with hardware and software for years, have finally got an ip6 ISP so at some point I'll actually be able to go native IP6 for the whole network with v4 as a fallback for older devices and Macs

 

As above though, total hassle to actually do however it will mean we avoid a stack of the issues as ip4 keeps circling the drain noisily.

The bigger companies such as Google started adopting and using IPV6 many years ago, and for a long while now if you are running IPV6 then you will end up on their IPV6 range. Quite a few of us internally and a "couple" of customers are using dual stack IPv4/ IPv6. We started running dual stack IPv4 & IPv6 in our network for us and our customers about 3 years ago, but the take up is VERY slow. I think problem is really two fold. Firstly for many people out there they don't even need a single static IP address, let alone see the reason for everything having a real world IPv6 address; and secondly, so much older network equipment that is out there in schools and businesses is not compatible, so as well as being a significant time investment there would also be a big financial investment too.
