Subject Re: blacklist IP addresses?
Date Wed, 30 Sep 2015 10:41:52 GMT

        If you don't want some address to be provided by VR - can't you 
exclude this from network range? At least cloudstack offers for IPv6 
start IP, end IP and CIDR specification. You may specify longer CIDR and 
start-end IP with smaller range. Thus some of the addresses will never 
be issued. Is this what are you looking for? I haven't tried this 
practically, so don't be rude if this does not work :)
