Need VPN server IP address list

Many VPN corps are listing their server IPs publicly. Where can I find a list of VPN Server IPs for whitelisting? Below wiki does not have a list: https://we.riseup.net/riseuphelp+en/vpn-howto#choose-a-server

some kind of trusted source would be nice: example. https://vpn.riseup.net/servers.json
