Once upon a time in the ip protocol there was INADDR_BROADCAST, and all
seemed happy.
from "man ipv6":
" IPv6 supports several address types: unicast to address a single host,
multicast to address a group of hosts, anycast to address the nearest
member of a group of hosts (not implemented in Linux),
IPv4-on-IPv6 to address a IPv4 host, and other reserved address types."
from net/ipv6/tcp_ipv6.c +582:
...
/*
* connect() to INADDR_ANY means loopback (BSD'ism).
*/
if(ipv6_addr_any(&usin->sin6_addr))
usin->sin6_addr.s6_addr[15] = 0x1;
...
Why it isn't supported? Is there a particular reason to follow this
BSD'ism?
Is it possible to achieve the same result of INADDR_BROADCAST with
multicast? The propagation has to be restricted only to the neighbour
nodes.
Best Regards
