Dynamic DNS with dns.com ip 4/6 dual stack

[schugk]

ip4/6 dual stack: if I use Dynamic DNS update clients to update the IP for ip4 and ip6 on dns.com I need to run two different update clients.

But dns.com has a problem with that and only keeps the last updated ip6 AAAA record.

dns.com has the option to update the ip4/6 adresses together:

https://{user}:{updater client key}@members.dyndns.org/v3/update?hostname={hostname}&myip={IP4 Address;IP6 Address}

but in the update URL i can only provide %IP% which is depending on the client ip4 or ip6.

Any possibility to have a variable %ip4% and %ip6% ?

thanks
Kai
