It is (or was) fairly commonly in use among internal nets which overflowed RFC 1918 or have to internetwork with other heavy users of RFC 1918 space. I know of at least two service providers and one cell network who were using it for that 3 years ago. Someone leaking internal routes for such? Or attempt to hijack the space? Only the Shadow knows... On Thu, Mar 21, 2013 at 11:17 AM, Donald Eastlake <d3e3e3@gmail.com> wrote:

Is anyone else seeing a lot of Class E address space (240.0.0.0/4) at their borders? Has this space been reinstated in some as yet unknown to me RFC? Thanks, Buz
