title: Do ip addresses change location?
body: <p>I've been asked to assign a country to a set of ip addresses associated with customer transactions going back a couple of years. </p>
  
  <p>Knowing that ip addresses are not fixed for a person obviously that ip address has to 'go' somewhere else. Looking a year or so on, is there any reason to believe this will return the correct country? If not, how far could it have gone?</p>
  
  <p>If I logged in the UK two years ago could looking up the country associated with this ip address now return France or Ireland.</p>
  
  <p>Rather round about way of asking <strong>are IP addresses fixed to a particular country or could they switch in time?</strong></p>
