They are one of the few VPN providers that give out public IPv4 addresses, and you can even get a static one. So, if you are using them for having a public IP, not for privacy, please continue doing so.
That could come in handy for hosting things behind double NAT.
Two other VPNs working for this purpose are OVPN (+1 for them using WireGuard, but their Singapore node is slow) and SwissVPN (limited to only 30 Mbps by contract, but they do provide these contracted 30 Mbps).
