DynDNS Service IPv6 Configuration

The DynDNS Service can also be used to perform DynDNS updates of computers, which are reachable by IPv6 addresses. However, you will need a DynDNS provider that accepts updates for IPv6 addresses.

The following access methods can be configured using the DynDNS Service:

 

Native IPv6 PublicIP

When the DynDNS Service has recognized a public IP address there already is a native IPv6 address.

The existing standard update URIs in DynDNS Service are mostly configured to perform IPv4 updates. Please check if your provider may be uses another update URI for IPv6. For example, some providers like to set the parameters ipv4 and ipv6 to distinguish between IPv4 and IPv6 addresses.

Example for IPv4:

https://dyndns.regfish.de?fqdn=[FQDN]&ipv4=[PUBLICIP]&forcehost=1&authtype=secure&token=[USERNAME]

Example for IPv6:

https://dyndns.regfish.de?fqdn=[FQDN]&ipv6=[PUBLICIP]&forcehost=1&authtype=secure&token=[USERNAME]

 

Conversion IPv4 to IPv6

When recognized an IPv4 address by the DynDNS Service. However, your computer is accessible under the IPv6 equivalent in IPv6 networks.

The DynDNS Service supports the tunneling mechanism 4-to-6 in order to update an IPv4 address at the same time as the IPv6 equivalent in their DynDNS provider. Please check if your provider may be using a special update URI for IPv6 updates. Please proceed as described in section "Native IPv6 PublicIP".

If you know the update URI of your provider for IPv6 addresses and the DynDNS Service recognizes a public IPv4 address for your computer, please use the variable [IP4to6] instead of [PUBLICIP] in order to their IPv4 address as the IPv6 equivalent to update in their DynDNS provider.

Example:

https://dyndns.regfish.de?fqdn=[FQDN]&ipv6=[IP4to6]&forcehost=1&authtype=secure&token=[USERNAME]



IPv4 Mapping

When recognized an IPv4 address by the DynDNS Service. However, your computer will be updated on an IPv6-based DynDNS provider.

The DynDNS Service supports the mapping mechanism IPv4 mapped in order to update an IPv4 address as IPv6 address in their DynDNS provider. Please check if your provider may be using a special update URI for IPv6 updates. Please proceed as described in section "Native IPv6 PublicIP".

If you know the update URI of your provider for IPv6 addresses and the DynDNS Service recognizes a public IPv4 address for your computer, please use the variable [IP4mapped] instead of [PUBLICIP] in order to update the IPv4 address as IPv6 address in their DynDNS provider.

Example:

https://dyndns.regfish.de?fqdn=[FQDN]&ipv6=[IP4mapped]&forcehost=1&authtype=secure&token=[USERNAME]

The IPv4 address is left completed with the prefix 0:0:0:0:0:FFFF::/96.

 

IPv4 Translated

When recognized an IPv4 address by the DynDNS Service. However, your computer will be updated on an IPv6-based DynDNS provider.

The DynDNS Service supports the mapping mechanism IPv4 translated in order to update an IPv4 address as IPv6 address in their DynDNS provider. Please check if your provider may be using a special update URI for IPv6 updates. Please proceed as described in section "Native IPv6 PublicIP".

If you know the update URI of your provider for IPv6 addresses and the DynDNS Service recognizes a public IPv4 address for your computer, please use the variable [IP4translated] instead of [PUBLICIP] in order to update the IPv4 address as IPv6 address in their DynDNS provider.

Example:

https://dyndns.regfish.de?fqdn=[FQDN]&ipv6=[IP4translated]&forcehost=1&authtype=secure&token=[USERNAME]

The IPv4 address is left completed with the prefix 0:0:0:0::FFFF:0::/96.
