1. Consider DNS. To refer to a node N in a sub-domain implemented as a different zone than the current domain, a name server for that zone needs to be specified. Is it always necessary to include a resource record for that server’s address, or is it
sufficient to provide only its domain name?

2. High level name servers in DNS, that is, name servers implementing nodes in the DNS name space that are close to the root, generally do not support recursive name resolution. Can we expect much performance improvement if they did?
