> IPV6 - When a Vm is expunged and a new Vm is deployed with the same name , 
> /etc/dhchosts.txt has 2 entries with the same name
> Steps to reproduce the problem:
> Create a ipv6 network.
> Deploy a Vm with name - test456.
> Destroy this VM. Wait for it to be expunged.
> Deploy another Vm with same name - test456.
> We see that there are 2 entries in the router with the same name "test456" 
> resolving to 2 different ipv6 addresses.

> Attaching management server logs:
> Have 2 entries for the same name is a problem.
> Is it also a problem to have the same ipv6 address associated with 2 
> different vms with different Vm names ( 1 expunged and 1 active , in my case 
> "test456" which is expunged and "testyoyo1" which is active) ?
