[dns-operations] 答复: L-Root IPv6 Address renumbering

[Davey Song(宋林健)]

Sorry but I have more question. 

If there is still non-trivial volume of traffic to L root after 6 month, what should L-root operator do? Is there any way to tell how much (percentage ) onetime resolvers change to new address ? Is there any evidence or experience to tell the traffic is generated by real resolver or scanning/monitoring system.

Hi Yasuhiro,

The existing IPv6 address will be kept in service for at least another 6 months after the transition or when we see less than 1 valid DNS query per second. Which ever occurs first.

Cheers
Terry
