Nameservice questions

[Charles Derykus]

I have several questions regarding nameserver:

  (1) Can nameservice resolve reverse translation queries "up the tree"
      towards the root domain if the domains of the requested node and
      the requesting node are at the same level, e.g.

      Nameserver Node		Domain
      ---------------		------
	cabbage			vegetable
	parsley			herb.vegetable
	carrot			underground.vegetable

       can "carrot" ask "cabbage" to reverse translate an I.P. in 
       "herb.vegetable"  and if so, how?
		
       We have gotten it to work only by specifying in the named.boot
       on carrot a line like the one below where 192.33.72.10 is the
       I.P. of parsley
     
       secondary	72.33.192.in-addr-arpa	192.33.72.10  herb.bak

       In other words,  carrot seems to have to know that parsley is
       authoratative for the herb.vegetable domain and doesn't seem to be 
       able to pull it down from a server such as cabbage in a higher
       domain.
   (2) A named.rev with multiple $ORIGIN lines worked fine on out primary
       nameserver for a while but then the secondary nameserver starting
       breaking. The only way we get it working now is by specifying separate
       reverse translation files for each $ORIGIN line, e.g.

       in the primary's named.boot:    

       primary	207.128.in-addr.arpa		herb.207.128.in-addr.arpa
       primary	79.33.192.in-addr.arpa		herb.79.33.192.in-addr.arpa


       in the secondary's named.boot:   (primary's I.P. is 128.207.254.44)

       secondary  207.128.in-addr.arpa		128.207.254.44
       secondary  79.33.192.in-addr.arpa	128.207.254.44

       Does nameservice break if these separate reverse files exceed some
       limit- either in number of files or memory capacity- as the 
       "named.rev" file apparently does? 

Thanks for listening. Any help greatly appreciated.
