Queries like;
dig @authoritative_name_server_ip zone_name  record_type

should have the "AA" (authoritative answer) flag set. If not
they must have obtained the answer via recursion. The situation
for "NXDOMAIN" is slight more complex so it only works for
records that exist, so I usually ask for the zones name servers
or SOA, since one NS and one SOA must exist.

dig @192.5.6.32 131.57.24.in-addr.arpa ns

I assume Solaris has "ping -n" to avoid DNS lookups.

Solaris ftp daemon use to insist on reverse lookup by default.
