Is it possible that after you attach to GPRS and then obtain your assigned IP address from the APN, that this address can be re-assigned even if you never lose the APN connection?
(Assume that I have a public, dynamic SIM account).
The reason for my question is - on power-up after obtaining GPRS then APN attachment, I update DynDNS (if neccessary i.e. if there has been a change to the assigned IP address from the previous time). Is it neccessary to check the assigned IP address once in a while even though connection to the APN is not lost? If so, is there a recommended ‘once in a while’ check time?
