[Dnsmasq-discuss] multiple dhcp6 servers

[Gene Czarcinski]

I got a bit of a surprise today when I discovered that it is not 
possible to run more that one dhcp6 server on a single host.  This 
appears to be true whether it is an ISC-dhcpd6 server and dnsmasq or two 
dnsmasq servers.  They each want exclusive use of UDP6 port 547.

With IPv4, you could run multiple dhcpd servers with each on dealing 
with a specific network and this is useful in qemu/kvm/libvirt 
implementation of virtualization where a dnsmasq is started for each 
virtual network.

I assume there is some reason for this situation and that it has 
something to do with how IPv6 protocol is defined.

OK, it is what is.  Is there some practical way to "tell" dnsmasq an 
association for a hostname and an IPv6 address?  I cannot see something 
like that used to update an authoritative name server but it would be 
useful to have some kind of an update capability with dnsmasq.

Comments?
