[rpd] [Community-Discuss] Cloud Innovation Displays Very Poor, If Not Criminal, Netizenship

[JORDI PALET MARTINEZ]

I don’t agree that it will take 20 years, at least not in most of the RIR regions, maximum a couple of them to reach more than 75% IPv6 traffic. I hope that African ISPs realize this soon and move on to IPv6.

 

IPv6-only with IPv4aaS (as a service) is the way. This means that transfers are needed but more often, you will see small prefixes being transferred, instead of big ones.

 

The point is that when you deploy IPv6 to eyeballs, the number of IPv4 addresses that you need is so low that the value is already lost, and in fact, selling your (then) excess IPv4 addresses to those that are lagging behind, you can pay for the cost of updating or replacing customer CPEs (which typically is the main issue), etc. Also, you can take the opportunity to provide the customers better CPEs (better WiFi, for example).

 

I’m not sure I’ve mention this before in this list, but our studies and customer cases demonstrate that using 464XLAT, typically 75% of the traffic will be already IPv6. If the network has a higher proportion of residential customers, these figures can go up to 85%.

 

(remember that most of the contents that most of the customers access, are already IPv6: Facebook, Google, YouTube, Netflix, Disney, etc., and all the CDNs/caches, all those represent typically more than 75% of the ISPs traffic).

 

This means that the cost of the NAT64 boxes and IPv4 addresses needed is very low.

 

In the worst case, an IPv4 /22 can easily hold 300.000 subscribers. If the implementation of the NAT64 is taking advantage of the 5-tuple, then it may become almost unlimited the number of subscribers, with the same prefix length.

 

I’m documenting that in our ID:

Just not having the time to finish it faster …

Jordi

yes!  spend your energy on migrating to ipv6.
help devalue, and make irrelevant, the ipv4 market.

 

Not easy to devalue a scarce resource which most fortune CSP out of San Francisco continue the rush to acquire from transfer markets.

 

I am not sure if their intentions is to stockpile IPv4 and render it useless (joking) or they are motivated by the economic benefits presented by the services they offer globally that heavily rely on IPv4 numbering thereby presenting significant value to IPv4 even though IPv6 does the same.

 


anything else is not a sustainable way forward.

 

I different school of thought believes that both protocols will continue to co-exist (transition  arguments debunked) until such time when there is significant IPv6 traffic from eyeballs some more years ahead (20 more years so many factors).

 

Cheers,

Noah
