Alternative to mesos-dns?

[Marc Roos]

It looks like mesos-dns does not report all ip adresses of a container. 
Is there an alternative for this?

I wanted to have a look at the source myself, but have dependency 
problems(??). What I have noticed is that the developer is probably not 
testing with multiple ip addresses[1]. And I think the problem is that 
there should be an array of IPAddresses[2]. (Maybe obvious, since I am 
getting the last result)

Below is my master output[3] with two networks.
