The "-n" parameter specifies how many icmp echo requests are sent out, not 
how many replies are solicited.

The pcap file shows 10 icmp echo requests and 2840 echo replies, and that 
the echo replies used 284 unique link-local ipv6 addresses associated with 
284 unique MAC addresses.  This looks both correct and consistent with the 
figures in the draft.  The lesson is that if you have a lot of ipv6 hosts 
on the same broadcast domain, you will get lots of echo replies from a ping 
to ff02::1.

Nalini, if you feel that there is an issue here, you should talk to your 
hosting provider and suggest that they don't put as many ipv6 hosts on the 
same broadcast domain.  This isn't a protocol level problem: it's expected 
and correct behaviour.
