Dynamic DNS question and update forwarding

[lawrence.a.kravets at us.andersen.com]

Okay quick question.

Here is my environment:

Two DNS servers Bind 9.1.2 and 1 Windows 2000 Domain Controller.

10.0.0.2 DNS Server 1 Master for      ad.zone.com  <- this zone is enabled for
dynamic dns and only allows ip addresses 10.0.0.2 and 10.0.0.3 to update

10.0.0.3 DNS Server 2 Slave for        ad.zone.com  <-update forwarding turned
on to pointing to its master.

10.0.0.4 Windows 2000 Domain Controller  <-its dns server that it points to
10.0.0.3


Okay here is my question.  The domain controller tries to do DDNS with DNS
server 10.0.0.3. DNS server 10.0.0.3 is not master for the ad.zone.com domain,
but it knows to forward DDNS requests to DNS Server 10.0.0.2.  What is the
source address that 10.0.0.2 receives?  Does 10.0.0.3 get the request and then
it try's to register 10.0.0.4 for it?  How does this scenario work?

Thanks,

Larry
