Connecticut address - Boston IP - Can't see yankee games on Amazon Prime

WHY does the IP for my home internet in CONNECTICUT always show up as being in Massachusetts???  It is annoying when I try to go to websites that "show your local store" and always show me stores in MA not anywhere near where I actually am, but now we are apparently blacked out to watch Yankee games even though we are within Yankee home territory and should be allowed to see the games on Prime - but because Xfinity shows our IP address INCORRECTLY we can't see the games.  [Edited: "Language"]???
