> No, you can ask your provider to announce the IPs for you via a private ASN, but I have not seen a provider that is cheap enough to do BYOIP without an ASN. Getting your own ASN is the best option.
BYOIP in AWS is free. and VPC have lot of customisable and all are well documented.

Probably the only part of that setup on AWS that wouldn't cost a fortune.
I've been running my own ASN for a while. I route both IPv6 and v4 back to my home network over wireguard. I use Vultr for one of my providers.
They have no additional charge for BYOIP and you can use their private ASN if you don't have your own: https://docs.vultr.com/support/products/network/can-i-use-my...
If I used AWS the bandwidth charges would probably be a bit high.
