Docker.local stops working even when xhyve vm is still running

Expected behavior

ping docker.local should always give a response when docker for mac is running (in nat mode)

Actual behavior

after a while it seems that docker.local stops working, even though the address of the current running VM is working.
If I do a ping 192.168.64.1 or a ping 192.168.64.x (where x is the current interation of the VM I guess) they both give response.

Doing a pinata restart does not solve the problem. After restarting my computer everything works again, but the ip-adress of the current docker daemon is 1 higher then before.

I don’t know what the role is of the 192.168.64.1 address, but this always work. It’s just the docker.local that does not resolve anymore. Furthermore I think it’s strange that the ip-address of the VM itself keeps increasing (right now I am already on 192.168.64.6).

pinata diagnose shows nothing special.

Steps to reproduce the behavior

I don’t know how to reproduce, but I have the distinct feeling that things go wrong after my mac has either been in sleep mode or changed wifi-networks with a longer time in between the starts.
