rdisc6: handy tool to see advertised IPv6 prefixes

If you want to see if there are any routers advertising IPv6 prefixes on your LAN, and if so, what IPv6 prefix they are advertising, you can use the tool 'rdisc6'.

Usage is easy: 

   rdisc6 -1 -r1 -q wlan0

Output is for example

   $ rdisc6 -1 -r1 -q wlan0

So, a good first check of your router.
