Re: BYOIP and AS prepend in AWS

Last I looked at this ( probably a year ago ) , any IPs you setup for AWS BYOIP were announced direct from AWS ASNs. There wasn't an option to put your own ASN in there, or modify anything related to the advertisement. On Mon, Jun 23, 2025 at 5:43 AM Hank Nussbacher via NANOG < nanog@lists.nanog.org> wrote:

Can someone explain to me how to BYOIP into AWS and use AS prepends?

Have been unsuccessful in finding how.

Thanks,

Hank
