# If you do not yet have an IPv6 Tunnelbroker.net allocation, you can get one (for free!) at:
|

# https://www.tunnelbroker.net/tunnel_detail.php?tid=584532
|
||||
##
|

# This is the tunnel ID. To get it, log into your tunnelbroker.net account and click on the tunnel you wish to use.

# The tunnel ID is the numerical string in the URL. e.g.:
|

# https://www.tunnelbroker.net/tunnel_detail.php?tid=12345

# The tunnel ID would be 12345 in the above example.

# This is your tunnelbroker.net username.
