DNS subnet prioritization

[jlazzaro]

Using Server 2003 R2, is it possible to do DNS subnet prioritization on a classful boundry?

I have 3 proxy servers being served round robin from a single A-record. If a client on the same /24 as one of the servers queries DNS, the local proxy is always returned first in the list; great, works as expected.

However, I would like all hosts in the same /16 as that proxy server to to return it first in their list. Possible?

You have netmask ordering enabled. It gives priority to ip addresses that are deemed closer to the client based off their ip address and subnet mask. If you want to use round robin and netmask ordering, you can read this article from Microsoft.

DAMMIT!!!!!

This is why microsoft has no business with anything networking related. I honestly think they are too stupid to be employed. That only reinforces the fact that:

There is the agreed upon standard across the world.
Then there is the microsoft way.

The two shall never be interoperable nor shall the MS way ever make sense. Standards be damned they say! This is what happens when you allow programmers contribute to RFCs. Too stupid for their own good.

It's an extra feature. I don't see the big deal in this instance. It gives their customers an extra option, plus you can turn it off easily. Just relax. :beer:

Plus thank programmers for RFC 2616.

i read that article, but i didnt read that article looks like its a simple regkey to change the netmask bits. thanks~!
