[ncc-announce] 128.0.0.0/16 configured as martian: Please update your routers

[Apologies for duplicate emails]

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.

We are exchanging the allocations that were already issued and for now 
we will (temporarily) stop using this specific /16.

The RIPE NCC is working on this matter. For now, 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

Best regards,
Ingrid Wijte
