I have set up an isolated DNS community, but would like to check that I have
set things up correctly.

We have a number of registered IP networks connected by bridges.
Most of the domains are below cam.ac.uk, but we also have cam-orl.co.uk and
cam.sri.com (aka sri.co.uk).

Are there any other sites running a similar setup who could spare a few messages
to check that I have got things set up correctly ?

My main concerns are:

1) Is there any reason to have NSs for the (empty) intervening domains
   (i.e. uk, ac.uk, co.uk, com, sri.com) ?

2) The Ultrix documentation mentions having "muliple primary servers".
   Is this correct ?

3) If a netmask is set to 255.255.255.128, is it possible to delegate a reverse
   IP map to each subnet, or would the two sunbets which shared the class C
   range have to cooperate in managing a single map ?

4) are there problems with sharing the map for cam.sri.com. with sri.co.uk. ?
