How do I find out my machine's IP address as visible to the outside world? Thanks a lot.
Most modern routers home routers support the IGD part of UPnP (http://en.wikipedia.org/wiki/Internet_Gateway_Device_Protocol). You can use an UPnP client software to query the router for its WAN IP, connection state and upload / download speed. You may even be able to modify the port forwarding rules with UPnP. I suggest Miniupnpc, because it has nice Python bindungs.
Another option is dyndns.org. You can register a new DDNS host, update it with a DDNS client and then query the IP with socket.gethostbyname(). Most modern routers have a builtin DDNS client, too.
