problems with sortlist

[Frank van den Heuvel]

We are using BIND8.2.2-REL on BSDI 4.0.1 and we have a problem with
sortlist.

In our named.conf we have added the following under options:

/* begin sortlist */
        sortlist {
                { localhost;
                  { 172.16.30/24; };
                };
                { 172.16.30./24;
                  { 172.16.30/24;
                        {172.16.40/24 ; 172.16.50/24 ; 172.16.60/24 ; }; };
                };
        }; /* end sortlist */

We also have a name that points to multiple addresses:
172.16.30.12
172.16.40.12
172.16.50.12
172.16.60.12

We expect 172.16.30.12 as first in the response if we query from localhost
or from a resolver with 172.16.30 address.
But we get an IP address back following the round robin mechanism, so
sortlist is not working as we expect it to work.

Is there anybody who knows why it isn't working as we expect it to work ?
