Back to the Past: IPv4 Browsing (Egress) Activated via NAT64

We can't let the Cloud Seeder team get all the attention...

"It works!" exclaimed Doc as the future Marty went back in the past using a Delorean armed with a certain invention, showing the inventor the finished version of his invention, the flux capacitor.

We definitely didn't have a moment like this, but we're still proud to have deployed NAT64 across all of our native locations, giving you access to the legacy internet through IPv6rs.

You will see a "NAT64" config in your panel if your gateway supports it.

What's NAT64?

NAT64 is simply Network Address Translation between IPv6 and IPv4. With NAT64, even though you're receiving an IPv6 IP from IPv6rs, you will also be able to browse the IPv4 web. This means you can now fully encapsulate your server appliances, and all their traffic and activity, securely into its own, isolated tunnel.

How does it work?

In our NAT64 setup, we utilize the combination of a tunnel and DNS server. When a DNS record lacks an AAAA (IPv6) record, the system creates a pseudo IPv6 and sets the domain to resolve to this IP. Traffic between this IPv6 and the destination IPv4 is tunneled in an unadulterated fashion affording it very high speeds and affording you access to the entire IPv4 Internet.

In contrast to SNI which only works with TLS, this works with all protocols.

Who else uses NAT64? Is it production ready?

T-Mobile, one of the largest mobile operators in the world, uses IPv6 natively. The IPv4 connectivity on their network routes through NAT64. Orange in the UK as well as many other providers exclusively use IPv6.

While, according to Google, adoption of IPv6 is at 41%, and growing fast, we argue that IPv6, which was called the future of the Internet, is now the mainstream internet as most netizens are actually using IPv6 since they are on mobile devices and the IPv4 space is exhausted (used up).

Will this Protect my Privacy?

For web, apps and general internet activity, using IPv6rs with NAT64 will provide you enhanced privacy by changing your IP and encrypting your connection.

Do I still need a separate VPN service?

Using IPv6rs for privacy, not just servers, works in most cases and will help you get around most regional blocks. However, we do not help you access the major streaming services. If this is your use case, you will still need another VPN who specializes in this.

For everyone else, IPv6rs is your OSS (one stop solution/open source software)!
