Are you allowed to and how can you trace a MOBILE IP internet address into a phone

number? I have a ip log of all the people who have looked at my email in the last month,
This month my email was hacked into and a unknown IP was there,
it came up at a ip 202.---.--.--
It came up at VODAPHONE HITCHINSON THREE, as a mobile 'ip' address for internet
Are you allowed to and How can you translate this IP address into a mobile number or make of a phone? :/

With just an ip address a normal person can trace it back to the corresponding ISP using sites like Ip-details.com .But even then hackers use VPN and other IP hiders for such activity.So best is contacting the police autorities.They have permission to greater extent hence they will be able to catch the hackers sooner.
