We will apply ipv6 from ARIN and try to use it in hosting business
1/ Can we use it in our current AS which is using ipv4? If not. Do we have to apply new AS?
No, you can route IPv6 & IPv4 from the same ASN.
2/ Can arin not allow us to apply ipv4 for the future after we apply ipv6?
If you need IPv4, apply for it. You might have a *better* chance if you already have a plan to implement IPv6, than if you have not considered it.
3/ Any advices to do ipv6 in hosting business
Software. Plesk barely has IPv6 support (>10.2) and I'm yet to hear about it from CPanel. Furthermore connection tracking in RHEL/CentOS 5 is totally broken for IPv6 if you're using it for IPv4 also... But mostly: you just have to dive in and see what works/what doesn't. Just don't test it on your live servers! Tom
