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 (if your VM has the IPv6 address in the range 2a0a:e5c0::/48)
  • 185.203.115.0 (if your VM has the IPv6 address in the range 2a0a:e5c0:2::/48)

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, with a proper MX record.
• Inform the ungleich team via support at ungleich.ch about your domain.
• Our team configure the proxy for your domain and come back to you.
• Add a second MX DNS record pointing to ipv6-mx.ungleich.ch, with lower priority (= higher priority number) than the original one (e.g. domain.tld IN MX 20 ipv6-mx.ungleich.ch.).
