I think one is enough, it is for machineID, one or all IPs are the same :)

Here is a risk that different instance may be get the same IP in multiple network environment (such as virtual network ), calculating all IP would be better when we can not confirm which is physical network interface.

So we can remove unused code and test case.
BTW: this is not a really random
, because here use the default random seed, so it will always output a certain int sequence.If we need to pick a ip, pick the first one would be better, it help to debug program.
