Re: Nord VPN
Do you mean using a static IP instead of using Nord VPN?
If you want an externally visible address so that you can access your devices from the internet, then a static IP will do that. There is a one-off charge from Plusnet, so it can be cheaper than a paid for VPN.
If you use a VPN to hide your real address or filter out malware, then of course a static IP won't help with that.
