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.

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
