Gosh, this one hasn't come up for a while !

It's the Remote Access Service which asks for a pile of addresses 
'just in case' another machine should call up. Either disable the RAS 
service on the clients, or try this :

if (substring (option dhcp-client-identifier, 1, 3) = "RAS") {
         ignore booting;

If you'd mentioned this in the first place you could have had the 
answer sooner.
