The range has only been announced for 2 hours. Just wait longer for filters to refresh as Ryan advised.

Neel,Carriers rebuild their prefixes lists once or twice in a 24 hour period. Considering that you just got the block today and is in ReliableSite's AS-SET, you just got to be patient.Having announcements propagated immediately either sounds like it happened a day after you gave them the LOA, or they have unfiltered transit circuits, which is worrisome.Ryan ------ Original Message ------ From "Neel Chauhan" <neel () neelc org> To nanog () nanog org Date 4/25/2023 7:35:40 PM Subject IPv4 Subnet 23.151.232.0/24 blackholed?Hi,I recently got the IPv4 allocation 23.151.232.0/24 from ARIN. I also had my hosting company ReliableSite announce it to the internet.Right now, I can only access networks that peer with ReliableSite via internet exchanges, such as Google, CloudFlare, OVH, Hurricane Electric, et al.It seems the Tier 1 ISPs (e.g. Lumen, Cogent, AT&T, et al.) are blackholing the IPv4 subnet 23.151.232.0/24. Could someone who works at a Tier 1 NOC please check and remove the blackhole if any exists?Normally when ReliableSite announced my prior (then-leased) IPv4 space it gets propagated via BGP almost immediately. This time it's not going through at all.Best, Neel Chauhan
