@Max, the issue of IPv6 address size is actually not one to be glossed over lightly. The definition of DNS getHostInfo calls return IPv6 *before* IPv4 addresses accroding to the RFC. These addresses are dynamically allocated in the spec. If I simply send a few thousand DNS responses to the device following a request, I can exhause device memory (DoS attack). Then the user is "supposed" to remember to free the allocated memory using another call. One missed deallocation and you've got a substantial memory leak.
