Otherwise, any one of the addresses assigned to the=20 interface should be used.=20=20=20 --snip-- So it IS permissible for another address to appear here. RFC 5942 that upda= tes RFC 4861 seems to not change this. This is probably why it works on Linux, windows, DragonflyBSD etc. I guess = they have seen this as the statement is quite clear.=20 /Peo --=20 You are receiving this mail because: You are the assignee for the bug.=
