Here is my update.
Just got off the phone with Cox Complete Care.
The IP assignments are random and there is a disclaimer in the Cox information pack in that they cannot guarantee the IP address assignment in one's particular area.
I tried resetting my external IP address, which was successful, but it assigned me again to the Tucson area.
The agent told me to try to reassign the IP address earlier in the day, but that does not make sense since most people have their computers running continuously. I then asked about geolocation assignment times, and he did not have that information.
In summary, my IP address has been assigned to a different region and I cannot do anything about it. I can sign up for a business account to get a static IP address as the only option.
In the meantime, I did not find resolution to my issue other than a proverbial shoulder shrug and "that's the way it is" answer.
I am not happy with the answer but there does not seem to be a correction available. Other than switching to a business account or DSL.
