As of today (29 June 2023), Port forwarding is not offered for new customers as part of the Pro plan. Further, existing IVPN Pro customers cannot reserve new ports. Existing reservations will stay in place, and can be disabled by manual action.

We are disabling all reserved ports and completely remove this feature from our service on 30 September 2023.

Almost any registar is good, except GoDaddy or Newfold Digital / Endurance International Group or Network Solutions.

I would suggest looking at TLD List for the major registar’s and their prices.

Regarding good website hosting, you have to find the one best for you (and your needs). You can go with what a registar offers, but some may offer other things you need.
