    I tether using my mobile.
    I need to be able to control the IP address that I get allocated.

    I've developed a mini program that logs the IP address I get.
    Restart the phone and you get a new IP address (better still, turn on and off airplane mode, gives you the same thing).

    So... I have a finite list of IP addresses.

    Is there ANY way I can control what IP address I get?
    Someone told me no... you JUST get randomly allocated.
    I'm guessing no... there *has* to be a way of getting a specific IP address?
    I know the IP address is available.

    I would add: the exact physical location where you access from matters (I think). So if I am on one side of the city and then move to the other side, then the list of finite IP addresses will change. This is my guess. BUT... in my case... I will always be in one location. I thought I would just mention this in case it mattered somehow.

    + Ignoring the fact that for whatever reason an IP address could be out of action for some reason. For the moment, let's ignore this possibility.

    Any ideas?

    A worst case solution would be to be able to rapidly get an IP address, drop it, get a new one and do repeatedly until the desired one was assigned. Currently the quickest way is to turn off and on airplane mode. But from start to finish, this can take 30 seconds.

    ALSO: I don't want to use a VPN.

    The answer is still no despite want you want to believe. Unless you own the cellular back haul equipment and create a reservation for your specific device to a specific IP. Dynamic IPs/DHCPs are called dynamic for a reason. You may get the same IP based on geographical location and lease parameters set by the network administrators of the cellular carrier. But there's no way for you to influence any of this.

    The other question is why do you care about what IP you get. Especially operating off of a mobile network.

    First Name:
    Public IP addresses assigned by the cell provider, or private IP addresses assigned by the mobile?
