IPv4 Subnet 23.151.232.0/24 blackholed?

Wed Apr 26 12:59:02 UTC 2023

Now this is kind of interesting.  I see route-views can see the route 
now...

BGP routing table entry for 23.151.232.0/24, version 2814701286

...

The only IRR route object I see for it is

route:          23.151.232.0/24
origin:         AS23470
descr:          Qeru Systems, LLC
mnt-by:         MAINT-AS23470
changed:        jcid at reliablesite.net 20230425  #01:09:36Z
source:         RADB
rpki-ov-state:  not_found # No ROAs found, or RPKI validation not enabled for source

and there appears to be no ROA.

According to https://lg.as6453.net/doc/cust-routing-policy.html, I would 
not have expected Tata to accept this route from RELIABLESITE (not based 
on the above route object), unless Tata is not using an IRR-based 
auto-generated prefix-list filter for RELIABLESITE, but rather a manually 
edited one.
