Rocky Mountain IPv6 Summit chairman Scott Hogg states that companies who have not done the least amount of prep work for IPv6 are guilty of too little, too late. In this interview presented on Tech Target, Hogg replies to the questions of why enterprises of all sizes should be concerned about the IANA depletion of addresses, what IPv4 address exhaustion means for your network and what will happen to the v4 Internet when addresses are completely gone.
“Things will continue to degrade for IPv4. Initially, the driver for IPv6 [adoption] was address space, but things will start to degrade for IPv4 over time. Users will be forced to go through large-scale NAT appliances, which will degrade their performance on the IPv4-Internet. Multiple layers of NAT for enterprises will cause more complexity and degrading of performance. We’re predicting a big spike in v4 routes, which will mean that maybe some [Internet service] providers won’t be able to carry the full routing table anymore. That can be a problem—if suddenly in v4 you can’t get certain places because your service provider can’t hold the full v4 routing table. So your performance with the v4 Internet might degrade over the next 10 years, I’m saying. IPv6 will become more attractive in the next 10 years as IPv4 really becomes tough to deal with.
