I found some explanation to scope in RFC 2373 page 14. Here is a paste:
---
scop is a 4-bit multicast scope value used to limit the scope of
the multicast group. The values are:
0 reserved
1 node-local scope
2 link-local scope
3 (unassigned)
4 (unassigned)
5 site-local scope
6 (unassigned)
7 (unassigned)
8 organization-local scope
9 (unassigned)
A (unassigned)
B (unassigned)
C (unassigned)
---
A scope of 0x1 would be node local and would need to be 0x2 possibly for one
to ping another host on the same LAN.

Ugh :P~~~. :)

I'm sure you're not the only one! ;)
