It's absolutely worth looking into and I'll get going on that, but I'd rather deal with it separately to the ipv4 stuff. IcmpSendEcho already appears to behave somewhat strangely, so I wouldn't necessarily assume that the ipv4 and ipv6 code will end up being identical.

This change checks that both the call and the ping were successful. In addition to that it takes a number of common failure causes into account before deciding to throw an exception.
