I understand about the Ip's that are static and dynamic. My question is if for example a person lives in Atlanta, can the Ip show up sometimes from Altlanta directly or can it show up sometimes show up as being within close proximity of Atlanta and also can the IP number on tis change even within close proximity? I aks this question because someone i know and know their original Ip adress always or most always showed up as a certain location with the same IP,, however recently i have been getting "views" from places that are suburbs of Atlanta. The reason i ask is that i know no one else within this area, but reently the IP's numbers have changed, yet still remain similar and are within a near location.

Depends entirely on the ISP. Possible, but there's no way to know for sure.

Hi. But I have another question. What if the IP is the same, but the computer isn't? For example, the IP is the same, but one time it was a Mac, another a PC? Does it mean it's the same person in the same building? Could it be another location?

True enough, which is why I referenced the ARIN lookup to further validate the source of the IP. But the higher order numbers changing is rare - it's much more likely that an ISP will assign the same connections out of the same lower order range. As you've seen, not impossible, just rare.

Actually, the first number of the IP changing with it being the same ISP isn't so unlikely. For example, they may have a block of IPs between 70.0.0.1 and 72.255.255.255 or something. When my IP changed (it is technically dynamic, but it stays the same for months) it went from 80.xxx.xxx.xxx to 81.xxx.xxx.xxx.
