A NAT VPS basically an IPv6-primary VPS with a shared IPv4 access.
You get fully dedicated IPv6 addresses (a /112 subnet - that's 65,536 IPs!) and a shared IPv4 address. This ensures dual-stack connectivity & compatibility with all environments.
The IPv4 is shared using a process known as Network Address Translation (NAT)
You get a static range of dedicated ports usable over IPv4. Make your application listen over these ports & you're ready to go!
It can be used similar to any other Normal VPS, some examples of the common possibilities include:-
- Host a full-fledged website (w any CMS like Wordpress, Ghost etc) using Domain Forwarding on port 80 & 443.
- Create your own private VPN - most methods including OpenVPN & Wireguard can be used.
- Ad-blocking VPN & proxy using AdGuard.
- Make website proxies for private & protected use.
- Create your own VoIP setup using Teamspeak, Mumble etc.
- Anything you want with native IPv6 - dns tests, website monitors etc.
- A simple remote terminal with root access, testing scripts & other stuff.
- A light usage remote desktop.
- Distributed database, Web Scrapers etc.
- Many more possibilities... :)
