Yes, with a majority of them I had already discussed. And we all agree that if there was IPv4 support in glite it would have been so much better. (Or, if we were grid middleware developers, which we are clearly not).
It's too bad that this one particular grid technology is not yet available using IPv6 but this is not the only way to build a grid. I think you are missing an opportunity to partner with developers and do something innovative that would benefit the larger community.
Has anybody ever done a large VPN-for-VMs IPv4 adress space allocation? I have never heard of something like that (end2end) but perhaps it exists; and am well aware though of some -open/public- IPv6 tunneling solutions.
Yes. <http://ws.arin.net/whois/?queryinput=N%20.%20AMAZON-EC2-2> <http://ws.arin.net/whois/?queryinput=N%20.%20AMAZON-EC2-3> <http://ws.arin.net/whois/?queryinput=N%20.%20AMAZON-EC2-4> The thing that worries me about giving any kind of special support to any sort of VM deployment is that it will cause the IPv4 address space to run out sooner. The consumption rate is no longer constrained to the number of CPU chips produced but now can grow faster which leads to a power law increase in demand.
In other words, reserving experimental IPv4 address space is no longer our first option, since normal IPv4 address space appears to be doable.
Good. It won't be too long before someone suggests changing policies to no longer accept virtual machines as a justification for address space. --Michael Dillon
