Is Comcast ripping me off more then normal?

I been having random DC from my games so I checked Speedtest to see if ping and what my up and down was.

I pay for 100 dowm 25 up and was getting 26 down and 13 up my ping was 172 . http://www.speedtest.net/my-result/4076513513 (thats the speedtest.net results)

I checked using  Comcast speedtest and got  98 down and  11 up ping 22 (http://stage.results.speedtest.comcast.net/result/775382624.png is the link to comcast tool.

The funny thing is its says my ip address is in Tucson, Arizona but i live in Alabama. here is ling to geo ip http://www.geoiptool.com/en/?ip=c-68-63-181-130.hsd1.az.comcast.net     Do I need to try to contact comcast again I have no vpn or anything set up  to make my ip adress diffrent.

Wish I had a net provider that ddint limit me to 300gigs a month

try to call comcast and see what they have to say, and make sure to record the call

Are u using wireless ?

Could be wireless, also comcast's speedtest gives higher results in my experience

No It's not a wireless connection.
