Is it possible for an iPhone to share IP addresses?

Question

Hi,

Is it possible for an Iphone from the same region to share IP addresses? I used a tracker. I found out that a stranger has been emailing me from an IP address..and a woman I'm involved with on the same IP address through an iPhone..

I need to know this before I send her an angry email..lol.

Answer 1

The IP addresses change and are unreliable without the proper logs (which the ISPs have and usually only gets seen when the law/police are tying to track someone by IP address). This is because of either/both:



1) The phones are sitting behind a thing called a NAT (see Ref A and Ref B below) which means that multiple phones can use the same Internet wide IP address (they will have different IP addresses on the ISP's own network). Therefore anyone outside sees the phones as having the same ip address.



2) The phones change IP addresses as they move around and get turned on and off. IP addresses can move around quite frequently, your phone could change IP addresses daily.



Technical reasoning (backing up what I say): As IPv4 addresses get low companies are NATing boxes and phones are a primary candidate, so phones may be NATed. It is becoming more common for ISPs to use dynamic ip addresses, and with phones the effect will be minimal (as they do not usually run servers).

Answer 3

Your internet IP address could be the same as other devices on the same network. For example, if you have a home network, all computers have different internal private IP addresses, but they all have the same external public IP address. Are you at a location that shares the internet with many devices (business, hotel, etc.)? If so, you'll have the same IP if they're also on the same network.

Answer 4

If its a static IP address, then yes, someone has hacked your internet, but if its dynamic then perhaps the person you have emailed has been assigned your apparent email and yours has switched. Check your IP again to make sure.
