標題： Re: IPv6 DNS server and tspc client setting
Dear Sir :
Yes, your are correct , the www.hexago.om does not
reply ping6 .
By using traceroute6 , I found the sit ipv6.heago.com
which did reply to my ping6.
Thanks.
1. How the DNS can be resolved in Ipv6 if there
> are no root DNS server in the Ipv6 Internet.
Refer to your reply,
Do you means that an DNS query starting by the IpV6
host in the Ipv6 Interent which will be able to reach
the Ipv4 root server than resolve it back . To make
myself clear on this concept, it may look like the
following DNS querying path :
Ipv6 Host --- send DNS query (i.e. www.abc.com) -- >
Ipv6 Internet
Ipv6 Internet -- forward DNS Query www.abc.com to)--
> Ipv4 Root server ( in Ipv4 Internet) .
Ipv4 Root server ( in Ipv4 Internet) -- querry the
abc.com DNS server -> abc.com DNS server
abc.com DNS server --- reply Ipv6 address for
www.abc.com --- > Ipv6 host ( in Ipv6 Internet)
Does it work in this way ?
Please correct me if I am wrong.
