https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235927 --- Comment #7 from Rodney W. Grimes <rgrimes@FreeBSD.org> --- (In reply to Loganaden Velvindron from comment #6) >Linux has already accepted a patch to allow assignment of 240.0.0.0/4: >https://www.spinics.net/lists/netdev/msg540240.html This patch appears to fix very ancient code that still treated this as part of the multicast space. The patches also add use of language (ClassE) that was obsoleted 16 years ago.=20=20 https://www.spinics.net/lists/netdev/msg539064.html is the correct reference to the message with the patch in it. >OpenWRT (major third party firmware) has accepted a similar patch: This is inline with what your asking for here. >A new ID will be submitted to the IETF soon. A new ID for what? Do you mean removing this from IANA reserved? >Please note that there were some attempts in the past in the IETF already: >https://tools.ietf.org/html/draft-fuller-240space-02 A 2007 attempt by Cisco, have you considered contact them about moving forw= ard with that draft? As it stands today the RFC say this is an invalid source address, so we sho= uld continue to respect those standards in a standard released product, however= I would not have a problem with #ifdef FOO_EXPERMINTAL disabling these restrictions, or a sysctl that did it. There are some much larger obsticles to getting this working on the interne= t at a larger scale, in that there are far too many firewalls that filter this range, and getting it out of them is going to take a long time. That time = wont even start until they are reclassed by IANA with an update to RFC6890 and y= ou would probably best get that done as it is the long lead show stopper to th= is idea. Getting FreeBSD, Linux and such fixed is pointless if people are goi= ng to continue to firewall this range. --=20 You are receiving this mail because: You are the assignee for the bug.=
