Re: MWEB legal department - call for assistance

HI Mark,

Interesting point you make, something that I have been pondering of late:

>The two types of Nameservers should be kept completely separate. A

>from the root. (And of course cache it for the designated time..)

Yes I agree 100% one has recursive and authoritative servers.

Lets work through the following scenario:

Just say I have both. My authoritative servers are responsible for 1000s of 
domains. Why would I want my tens of thousands of eyeballs, going to the 
root servers, inducing extra latency when if they could just look at the 
authoritative server, the responses would be much better.

OK, one reason is that it would break DNS sec, but for smaller ISPs, it is 
very important to keep the DNS for your clients up. If your upstream were to 
loose connectivity the return to root, causes even your directly connected 
clients to loose connectivity (DNS) to you. Yes, I might have other routes 
to get to the root servers, but other levels of the DNS tree, so might know 
where to look for .za, but can't get to them to look for co.za

Any thoughts?
