To whom it may concern,


We---at Kasetsart University, Thailand [Reference: https://rdap-web.apnic.net/autnum/AS9411]---are in the process of strengthening our routing security against (BGP) Route Hijacking.

We have already registered all of our prefixes with the APNIC RPKI Trust Anchor.
We present the following URL as an authentication of prefixes ‘ownership’.
[Reference: https://rpki.cloudflare.com/?view=explorer&validateRoute=9411_&asn=9411&extendedMode=false]

However, your database is currently announcing 1 fake entry incorrectly listing AS4750 as the origin of *our* 158.108.0.0/16 netblock.
[Reference: https://bgp.he.net/net/158.108.0.0/16#_irr]

That fake entry represents a security threat to our network.
Any AS that implements IRR-Only Route Filtering will obviously trust your database and thus will divert our traffic somewhere else.

We therefore humbly request that you take down that fake entry.

If you have any questions, please feel free to email me using the addresses in the signature section.

Thank you in advance for your help.


Best Regards,

Pirawat.
