The address you are attempting to ping is a subnet router anycast address (see the latest ADDRARCH draft). It usually identifies an interface on a router that is advertizing a given prefix.
If your router support this type of address, the response will come back from the unicast address configured on the routers receiving interface. -vlad Juan Francisco Rodriguez Hervella wrote: > Hi: > > I've observed that if I make this ping: > > root@mira:/usr/home/jrh# ping6 2001:720:410:1001::0 > > Where my prefix is 2001:720:410:1001::/64, it's answered by my > own host: > > PING6(56=40+8+8 bytes) 2001:720:410:1001:290:27ff:fe86:93d --> > 2001:720:410:1001:: > 16 bytes from 2001:720:410:1001:290:27ff:fe86:93d, icmp_seq=0 hlim=64 > time=0.334 ms > 16 bytes from 2001:720:410:1001:290:27ff:fe86:93d, icmp_seq=1 hlim=64 > time=0.448 ms > > I know that it doesn't exist "IPv6 broadcast", because it > has been superseded by multicast addresses, as it's told by RFC > 2373 [ADDRARCH]. > > Then I suppose that it could exist a host with Iface ID = 00...0, so how > can I ping to that host ? is it forbidden in any RFC (tell me where pls > :) ? > > Thanks! > -- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Vladislav Yasevich Tru64 UNIX - IPv6 Project Lead Hewlett Packard Tel: (603) 884-1079 Nashua, NH 03062 ZKO3-3/T07 --------------------------------------------------------------------- The IPv6 Users Mailing List Unsubscribe by sending "unsubscribe users" to [EMAIL PROTECTED]
