I remember reading about setting specific prefixes as residential maybe that was via geofeed or whois comments, also it seems like you basically need a separate AS for broadband customers if you do any type of hosting or colocation as it will likely get flagged as vpn On Thu, May 15, 2025 at 12:34 PM Eric C.

Has anyone else experienced a sudden increase in the past 2 weeks of blocks getting flagged as "VPN" or "Proxy?" We have some older leased space from HE and Cogent that got hammered seemingly all at once. We've started accelerating our migration to our ARIN space, but it's still odd why it's all of a sudden.
Most of the addresses are between 32:1 and 256:1 CGNAT pool IPs, and there are other 256:1 IPs that remain unaffected. Each customer behind an IP is in the same subdivision.
