So the server sends back two records instead of one, and the client just discards the one it can't use. That's not very efficient (stupid server!)
How is the server to know whether the requester can use IPv6 addresses?
An IPv6 capable requester will use the DNS server's IPv6 address. Any requester directing it's inquiries to the server's IPv4 address could be presumed incapable of using IPv6.
As I mentioned in another note, DNS requests on my local network can be either IPv4 or IPv6, but all computers can access IPv6 sites.
Doesn't this just mean that your network has built-in backwards compatibility so it can support legacy 'IPv4 only' systems? Certainly it doesn't mean that your IPv6 systems are pestering the DNS server on it's IPv4 address? :-) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
