bpclntcmd -pn is failing

bpclntcmd -pn is hunging

Our Master has 2 ips, I want the client to communicate with master with one only one IP from where client can communicate but the problem is cleint is pointing to the second ip of master server.

GOOD IP : 100.6.1.14 ( I have added this in /etc/hosts )

BAD IP : 14.3.1.14 ( I havent added anywhere in the client)

sapcigv:root> ./bpclntcmd -hn master-nb
host master-nb: master-nb at 14.3.1.14
aliases:     master-nb     14.3.1.14

I want bpclntcmd to point to 100.6.1.14 instead of 14.3.1.14, please help on this.
