github.com/ejrv/VPNs/ has not been refreshed in 24 months. https://github.com/X4BNet/lists_vpn/ seems to have replicated that effort for ipv4. No new source found for ipv6 Pros: - Code for generation is in repository Cons: - Unsure about quality. Lots of ASN as source of data. - No IPV6 data Comparable open source sources: - Firehol https://github.com/firehol/blocklist-ipsets / datacenter.ipset . Source data (https://github.com/client9/ipcat) is outdated from 2019 - https://github.com/jhassine/server-ip-addresses limited provider list - https://incolumitas.com/pages/Datacenter-IP-API/ API, smaller list Others sources seem commercial (Udger, securitytrails)
