Hello Kevin,

What's BIND 9's "view" feature?

This is because Stanford::DNSserver framework doesn't have the same
convenient config directives like BIND.So I just return a CNAME from
this custom-built dns server,and this CNAME would be paresed to an A
address finally by main DNS (BIND).

Yes this is the thing I'm confused for.Does BIND support the feature
of differentiating the answers based on the address range(s)
containing the source addresses of the queries?

Thanks,
