Introduction¶

To enable IPv6 only VMs to be accessible from the IPv4 Internet, we have an IPv4-to-IPv6 proxy.

HTTP proxying¶

• Configure / setup your website to be reachable by IPv6
• Ensure that your domain name has an AAAA entry pointing to your website
• Inform the ungleich team via support at ungleich.ch about your domain
• Our team will setup the proxy to whitelist your domain
• Setup an A entry for your domain(s) pointing to 185.203.112.54

SMTP proxying (experimental)¶

This service allows you to receive emails from the IPv4-world on an IPv6-only node.

• Configure / setup your mail server to be reachable by IPv6.
• Inform the ungleich team via support at ungleich.ch about: your domain name (e.g. domain.tld for jhon.doe@domain.tld) and the address of your mail server (e.g. my-ipv6only-vm.domain.tld).
• Our team configure the proxy for your domain and come back to you.
• Add a MX DNS record pointing to ipv6-mx.ungleich.ch (e.g. domain.tld IN MX 10 ipv6-mx.ungleich.ch.).
