VPN list is outdated

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 Source data (https://github.com/client9/ipcat) is outdated from 2019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)
