DNS Lookup. How can we disable Reverse DNS lookup in QNX  
Hi,

When I try to ftp (or telnet as well) to my QNX host it takes about 60 secs before I really get the connection.
Looking at Wireshark Logs i see that the host generates Reverse DNS Lookup packets towards DNS Servers configured in 
resolv.conf. (e.g. Queries of type 130.255.168.192.in-addr.arpa).
I do need DNS Server for Domain Name Resolution however there is no need for Reverse lookups.
Is there any way to disable these Reverse Lookups?

Thanks and Regards
Sajal Malhotra
