Class E addresses in the wild

Thu Mar 21 19:06:28 UTC 2013

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...
