📡 Filtering Fake "Residential" Proxies: Identifying DatacenterHosting ASNs Masquerading as ISP IPs

AS

Half the budget 'Static ISP Residential' proxy providers are just leasing Cogent/Leaseweb/Choopa subnets with updated WHOIS org names. Before buying a subnet, always verify the IP against `ipinfo.io/privacy` and `scamalytics` to ensure `hosting: false` and `asn.type === "isp"`.

Also check the TCP SYN MTU and passive OS hop count (`p0f`). Real residential connections sit behind PPPoE/DOCSIS routers with MTU 1492 or 1480, whereas fake ISP datacenter boxes show standard 1500 Ethernet MTU.
