Grimes from comment #4) There is a scheduled talk about this effort at netdev: https://netdevconf.org/0x13/session.html?talk-ipv4-unicast-expansions Linux has already accepted a patch to allow assignment of 240.0.0.0/4: https://www.spinics.net/lists/netdev/msg540240.html OpenWRT (major third party firmware) has accepted a similar patch: https://git.openwrt.org/?p=3Dproject/netifd.git;a=3Dcommit;h=3Dcd089c52de96= e47cf99410f66701e04e24155b9a A new ID will be submitted to the IETF soon.=20 Please note that there were some attempts in the past in the IETF already: https://tools.ietf.org/html/draft-fuller-240space-02 At the time it was perceived that ipv6 would take over faster. However, the adoption of ipv6 has been slower than expected.=20 See this thread also: https://www.mail-archive.com/cerowrt-devel@lists.bufferbloat.net/msg05838.h= tml --=20 You are receiving this mail because: You are the assignee for the bug.=
