Hi, I've submitted a patch a couple of times that adds more detailed information in ip.7 about how the Linux kernel treats reserved IPv4 addresses. (There is some discussion already there, but it's not entirely comprehensive and up-to-date with respect to the current behavior.) I'm paying attention to this because I've been actively involved in efforts to get the kernel to treat these addresses more permissively than historical standards suggest -- which it indeed does. I haven't gotten any feedback on my patch on the occasions when I've submitted it, so I thought I'd ask directly whether anyone is interested in reviewing it or discussing it, or whether there would be any interest in expanding the documentation on this point under any circumstances. Thanks! (specifically, Linux now permits you to assign the lowest, or "network", address on a segment as a unicast address; it has for several years permitted you to assign addresses from within 0/8; it has for many years permitted you to assign addresses from within 240/4; and all of these are also accepted as valid unicast destinations -- none of which users would assume just from reading RFCs!)
