Hi,
I wanted to know what would be the correct behavior for the following
scenario.
Suppose a mix(include both IPv4 and IPv6 host) network with a NAT-PT and DNS-ALG deployed
on the border. An outside IPv4 client host sends a A query, thru NAT-PT, to a DNS
server in this mix network. NAT-PT RFC says that a A need to be translated into AAAA,
but if the host in this mix network been queried is an IPv4-only host, the result will not be correct.
The RFC really doesn't say anything like that.
Should DNS-ALG need to query the DNS server in this mix network before it translates the A to AAAA?
Thanks
