That's good, if you find route objects in AfriNIC, there was some
authorisation for creating them.
Anyone (who pays some-hundreds $$) can create route objects in RADB.
RADB doesn't care/check if they are the owners.
Patrick has shown that the entry in RADB with the correct Canar AS was
actually created by EMIX (Etisalat). They do that very often for any of
their customers, too aggressively....
RADB is not an RIR, do not have their own knowledge which IP blocks are
assigned/allocated to whom and whether a request to them comes from a
source "authorised" for those IPs... they only know that it came from a
paying customer ;-)

RADB is syncing *into* their DB from other IRRs. AfriNIC, RIPE, surely
In  below you see one of my $dayjob's prefixes.
We once talked to EMIX, and they promptly created this entry in RADB.
probably the same was the case with Canar.
But since I have the same route object in AfriNIC, and AfriNIC means
it's really from the authenticated resource holder - so this is a
I should actually get EMIX to remove that RADB entry.
And *after* they create the AfriNIC route object, I think Canar should
do the same.
And since it used to be in RIPE DB, you see RIPE-NONAUTH as well.
The 2 objects from RIPE and AfriNIC were automaticall imported by RADB,
and you can recognise them using the "SOURCE:" attribute.
> and as Nishal's said this is always CANAR prefix , so how come RADB accept different origins for the same prefix.
... they just do...
and that means there is more garbage in there.

Thank you too for getting this going.
