      IF you can get it, spend a few extra $$$ on a static IP.   
      Makes things a LOT easier.   
      
      To deal with dynamic IPs ... first off there are $$$   
      services. Basically they monitor your real IP, then   
      update DNS servers to match per change.   
      
      However I don't like paying extra $$$, or giving   
      commercial entities too much access/info.   
      
      So, I wrote a little Python sockets daemon that   
      polls for a coded packet from the dest - plus   
      one for the dest that detects an IP change and   
      sends it on via the tiny packet over a selected   
      port. The client polls this port, and uses the   
      packet to update the current IP address. A   
      'personal' version of DDNS utils. Not 'public'   
      however, no providers DNS nums are changed. COULD   
      be in theory though ...   
      
      If I can find it in The Mess I could post the   
      daemon/poller code. Not very flexible, but   
      it worked ok for years. Thing is, the desired   
      target for the IP daemon WAS a static IP. For   
      broader use you'd have to have the same or   
      post the info elsewhere (a provider acct   
      that offers ssh access to a file maybe.
