Let's say normal IPs are $35, those blocked IPs may be $32, and you'll need much work to delist from all database. xTom GmbH ________________________________ From: NANOG <nanog-bounces+david=xtom.com@nanog.org> on behalf of Ross Tajvar <ross@tajvar.io> Sent: Wednesday, May 19, 2021 4:20:14 PM To: North American Network Operators' Group <nanog@nanog.org> Subject: Buying IPs with poor reputation I'm curious if anyone has experience deliberately buying blacklisted blocks, or blocks that otherwise have poor reputation. Is there a significant price difference? How do you seek them out? Most of the sellers I've found seem to focus on blocks with good reputation, or on improving the reputation of a bad block. But I am interested in purchasing some IPs for internal services where reputation doesn't really matter. Thanks, Ross
