Hi all.
Another request about DNS.
Do you know if it's possible for a DNS server to resolve IP for the same
name based on the source IP address of the request?
I mean, when a server receive a request for the IP of host.test.com, can it
respond "address is 10.0.0.1" if the request came from 192.168.0.1 and
respond "address is 10.1.1.1" if the request came from 192.168.10.1?
Thanks.

Hi
I think you're referring to netmask ordering feature

Netmask ordering will match the record to the closest subnet, if the request
came from 192.168.0.1 and its only choices are 10.0.0.1 and 10.1.1.1 MS DNS
will use round robin because there's no match. If round robin is disabled it
will send the records out in the same order everytime, and I don't think
there's a way to tell DNS which order to use.

Master Kevin spoke again wisely (as usual), although the article explains I
forgot to mention that only works for records from to the closest subnet.
