Configuration problem in different networks

Hello Folks,

 

I have installed BIG-IP on my VMware Player and whenever I go to college or at my friends place I need to change the IP address, Subnet mask, and Default gateway which takes enough time to reconfigure it again. So is there any way I can avoid these types of issues??

 

Also, if suppose my machine has IP address 150.156.22.44 and the SM is 255.255.240.0 then do I need to put the same SM in the configuration utility?

 

Thanks in advance.
