linux redhat why resolve.conf is change

0

I have a very strange issue in my linux machine - redhat 6.7 version

when I update my resolve.conf file as the following:

 options attempts:2
 options timeout:1
 search usa.Pe.corp  tedcruz.usa.fb.corp
 nameserver 10.9.145.145
 nameserver 10.9.100.103
 nameserver 43.11.0.14 

after service network restart I get different resolve.conf file as the following

 options attempts:2
 options timeout:1
 search usa.Pe.corp 
 nameserver 10.9.145.145

please advice how to disable/block the resolve.conf file from any changing?

please advice why the file is change after network restart or after reboot

yael
