[Is the IP of visitors who click on ads we also affect the CPC should we get?]
Yes, IP address matters. Advertisers are allowed to define specific areas that their ad will display. So if your visitor is from an IP address that originates from a city or area that has a lot of competing advertisers then the CPC will tend to be higher, however, if the visitor’s IP originates from an area where there are few advertisers targeting you will tend to have much lower CPC.
