How can i relate CI and Location ??

Hi,

 

I have imported some location and i have discovered some ci also ..

 

I want to relate these location to the corresponding CI by this way :

 - declare range IP in a (new ????) location field

 - if the CI's IP adress correspond to the range of a location, the system will relate it automatically (or i imagine to relate the two attibutes in a view for example) ...

 

Any best practices to do that ?

 

thanks in advance
