mindbuilder writes "Geoff Huston, chief scientist of APNIC, is saying that part of the reason for World IPv6 day is that internet content providers are worried that carriage providers are going to take advantage of the transition to widespread NAT to somehow control access to their customers and make content providers pay extra to carriage providers.
Carriage providers on the other hand see World IPv6 day as almost like a huge denial of service attack against their networks. Among other things they’re worried that they will be swamped by expensive tech support calls as customers can’t get to their favorite web sites. Some carriage providers are planning to block IPv6 traffic on World IPv6 day to protect their networks.
Meanwhile, the fact that many ISPs pay extra for equipment to put millions of internet users behind NAT and TAKE AWAY IPv4 addresses, even though they could get IPv4 addresses practically for free, makes it look to me unlikely that a lot of ISPs will pay extra to do the opposite and give out IPv6 addresses any time soon."Link to Original Source
mindbuilder writes "Internet Service Providers can today get IPv4 addresses for all their customers practically for free (except recently in the APNIC region). Yet the ISPs still put hundreds of thousands of users behind NAT. They do this to spite the extra equipment costs of NAT. If they're willing to pay extra to NOT give customers IP addresses, Why would they want to pay extra to upgrade their systems and give away IPv6 addresses, any time soon?"Link to Original Source
mindbuilder writes "It is said there are ISPs with hundreds of thousands of users behind NAT. I used to assume this was because they had to pay a small but non-negligible fee for IPv4 addresses. But someone pointed out to me that you get all the addresses you want for a low yearly fee. The difference between the fee for small ISPs and the biggest ISPs is only about 3000 Euros. That seems negligible for a large ISP, even one in a poor country with fierce competition, especially when you factor in the cost of NAT equipment and management.
So the question is: If they can get IP addresses now for nearly free, why don’t they? If they don’t want the IP addresses, are they even going to care when IPv4 addresses run out? Is the incentive to give customers IPv6 addresses ever going to overcome whatever disincentive there is now to give customers IPv4 addresses? Will we have to wait multiple decades before they decide to enable IPv6?"Link to Original Source
mindbuilder writes "The Asia Pacific and Australia region has officially run out of Internet protocol version 4 addresses today. Actually they have a few left but they've begun their "final eight policy", so addresses will only be dolled out in tiny quantities over the next several years. Even regions with addresses still available will be effected by this because making contact to computers in the APNIC region will get harder as more APNIC users have to start sharing addresses from behind NAT. If you or your family are in the market for a wireless router or other network gear, be sure to look for IPv6 compatibility."Link to Original Source
mindbuilder writes "At the rate the Asia pacific region has been consuming IPv4 internet address this year, it is expected that they will run out before the end of April, and perhaps closer to the beginning of April. Even if your region will still have addresses available, the sharing of addresses using NAT that will be necessary in the APNIC region will cause communications problems for users in every other region trying to contact APNIC users. Therefore it would be best if users in every region start moving to IPv6 as soon as possible."Link to Original Source
