Fixed in 2837bb31.

Not that this requires a dual-stack configuration.

Implementation hint: the dotted representation is only allowed for the last 32 bits.

I was testing out some of the socket examples with an IPv4 mapped IPv6 address and found that ip6addr_aton() fails when encountering the dotted quads section of the IPv4 mapped address


socket_examples_init() calls ip6addr_aton() which hits the "unexpected digit" case when the first dot is encountered:
