Hi folks,
I just want to check if there is any way to check whether any particular
segment (I am interested to know whether 240e:2000::/19 , which was allotted by
APNIC in 2018) was ever announced to the Internet.
Thanks,
Gaurav Kansal

Hi Gaurav,
There are route-collectors hosted publicly that do keep record of BGP
advertisements. I just checked the given prefix on one such service
provided by RIPE NCC
<https://stat.ripe.net/widget/routing-history#w.resource=240e:2000::/19>
and found that the given prefix has been announced from any ASN.
The only relevant announcement recorded after 2018 is by AS9498, but that
is for the complete 2400::/12. I would consider that as a route leak
instead of a valid announcement.
Thank you.
Rahul
