When my cellphone accesses a website via the tower and its GPRS gateway, NAT ensures that the sites receive a public IP. Would all phones using a single tower have the same IP?
- If yes, then how can the mass of received HTTP data routed to the correct cellphone? And how can websites differentiate between cellphone visitors? Is there additional HTTP header data?
- If no, then how are these unique IPs assigned? Based on availability or location? Would each tower have a fixed set of IPs?
