IPv6 not working when using fritzbox_ip arg

[realbadidas]

When I use the fritzbox_ip arg, the ipv6 arg gets ignored. Only A records are getting updated. I am not sure if the problem is the script or my router though, I haven't looked at the code. Using the default config it updates both.

Because we only get the IPv4 Address:

$ curl "http://fritz.box:49000/igdupnp/control/WANIPConn1" -H "Content-Type: text/xml; charset="utf-8"" -H "SoapAction:urn:schemas-upnp-org:service:WANIPConnection:1#GetExternalIPAddress" -d "<?xml version='1.0' encoding='utf-8'?> <s:Envelope s:encodingStyle='http://schemas.xmlsoap.org/soap/encoding/' xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'> <s:Body> <u:GetExternalIPAddress xmlns:u='urn:schemas-upnp-org:service:WANIPConnection:1' /> </s:Body> </s:Envelope>" -s

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<s:Body>
<u:GetExternalIPAddressResponse xmlns:u="urn:schemas-upnp-org:service:WANIPConnection:1">
<NewExternalIPAddress>123.123.123.123</NewExternalIPAddress>
</u:GetExternalIPAddressResponse>
</s:Body>
</s:Envelope>%

We could also get the IPv6 Adresse from the Fritzbox, but I don't see the point in doing so, unless you want to point your domain explicitly to the Fritzbox, is this what you want to achieve?

Here is an example for IPv6:

$ curl "http://fritz.box:49000/igdupnp/control/WANIPConn1" -H "Content-Type: text/xml; charset="utf-8"" -H "SoapAction:urn:schemas-upnp-org:service:WANIPConnection:1#X_AVM_DE_GetExternalIPv6Address" -d "<?xml version='1.0' encoding='utf-8'?> <s:Envelope s:encodingStyle='http://schemas.xmlsoap.org/soap/encoding/' xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'> <s:Body> <u:GetExternalIPAddress xmlns:u='urn:schemas-upnp-org:service:WANIPConnection:1' /> </s:Body> </s:Envelope>"

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<s:Body>
<u:X_AVM_DE_GetExternalIPv6AddressResponse xmlns:u="urn:schemas-upnp-org:service:WANIPConnection:1">
<NewExternalIPv6Address>2001:aaaa:bbbb:cccc:1111:2222:3333:4444</NewExternalIPv6Address>
<NewPrefixLength>64</NewPrefixLength>
<NewValidLifetime>12345</NewValidLifetime>
<NewPreferedLifetime>1234</NewPreferedLifetime>
</u:X_AVM_DE_GetExternalIPv6AddressResponse>
</s:Body>
</s:Envelope>%

oooh, i completely forgot that ipv6 gives each device a different address, whoops, still thanks for the reply.

I implemented it anyway, it might be a very niche use case but if some one wants to point their (sub)domain to their fritzbox, e.g. for a VPN connection, they are now able to do so.
