I will concur with Dave (K9DC) about Vultr support of BGP for 44-NET. I have been using Vultr at the Dallas data center for a couple of years. I started using a VPN with 44-net addresses for IRLP and EchoLink nodes before IRLP started providing them.
One of the features Vultr offers with BGP is the ability to run multiple VPS instances configured to use one /32 (or more?) address from your /24 subnet. This feature is also used to provide "high availability" capability.
I recently had a reason to try this capability. But I discovered the network was not routing between my two VPS instances using my /32 addresses. Vultr investigated and reconfigured their network to resolve the issue. I just add a bgp community they created to my bgp configuration on each VPS using the /32 addresses.
I am hoping, someday, Vultr will allow VPS instances to be created without requiring a Vultr assigned public IPv4 address. That should reduce cost a bit. But at $6/mo for my requirements, I am not complaining.
