Hi!
My router is only able to issue one GET-query with placeholders for the IPv4 and IPv6 address to update a dDNS provider.
So I wanted to propose adding query-parameters to trigger updates of both the A and AAAA record from one query. From a quick look it seems this would need some additional mechanics in the UpdateIp function. I'd propose adding the type-explicite parameters myipv4 and myipv6 while keeping myip with automatic type determination around for backwards compatibility.
Cheers,
Jörn
