I shouldn't have used the word "specified" when talking about the RFC and maybe re-written my question so apologies - it's late here. To sum up, is FreeBSD intended to support the strong host model for IPv6 as described in that RFC? As my tests don't seem to show it as not doing so, which seems contrary to what the KAME book suggests. However I can't find any specific wording on this on the internet or freebsd site. If this is so, is there any sysctl or other mechanism which I've missed which enables said strong host model - or am I stuck? As you have pointed out, RFC 1122 is 23 years old and covers a lot of the basics of what IP networking is and as a result has a significant number of updating RFCs. I simply point to it for the definition of strong ES model which is not redefined, and is referenced in the FreeBSD code base for at least IPv4 in ip_input.c. Next time I'll just say "strong host model". AlexY
