Hello Sir, I am Working with 3 Tier Data Center Organization as a Linux Expert, I have more than 3 years experience over Linux Servers, working on more than 1000 of Cpanel servers. We are doing IP rotation for proxy servers in our organization to avoid blocking over search engines. I will setup IP rotation for you. Please let me know the reason of IP change so that I can create script or appropriate setup for that. I'm ready to work on this.
