Hi Alex, In Dayton, Ohio, US, we are not seeing any 128... routes from TWTC (AS 4323). In St. Louis, Ohio, US, we are seeing the 128.0.0.0/21 via Level 3 (AS 3356). David Swafford, Sr. Network Engineer, CareSource On Mon, Dec 5, 2011 at 10:20 AM, Alex Le Heux <alexlh@ripe.net> wrote:
Dear Colleagues,
The RIPE NCC is aware that 128.0.0.0/16 is configured as a martian by default in (some) Juniper OS, even though RFC 5735 and RFC3330 outline that this /16 should no longer be reserved as specialised address space.
All allocations that were already issued have been exchanged and for now we will hold this space in quarantine.
We urge everyone to change the default behaviour of their Juniper routers:
set routing-options martians 128.0.0.0/16 orlonger allow set routing-options martians 191.255.0.0/16 orlonger allow set routing-options martians 223.255.255.0/24 exact allow
128.0.0.0/16 has been added to the RIPE NCC's Debogonising Project:
http://www.ris.ripe.net/debogon/
To facilitate testing, the following prefixes are being announced:
prefix pinagble address
128.0.0.0/16 128.0.0.1 128.0.8.0/21 128.0.8.1 128.0.24.0/24 128.0.24.1
