1) get
	Easy as going to http://tunnelbroker.net <http://tunnelbroker.net/> and filling out a form. Remember to check the box for your /48.

2) keep
	Admittedly, you might have to connect to your tunnel every once in a while to keep it alive, but thatâ??s
	hardly a high bar.

3) move
	If youâ??re not talking to the internet with it (which you canâ??t with ULA, theoretically), you can move that same
	HE /48 anywhere you want, with the additional advantage that you can, if you need to, connect your tunnel
	and actually make it work on the internet too.

You really think that doing ULA according to the RFCs (collision avoidance algorithm and all) is easier
than filling out a form at HE? REALLY?

I hear you, but Iâ??m not convinced about the ease.
