The virNetworkDHCPLeases struct was made according to the lease
parameters returned by dnsmasq. Are you suggesting that libvirt might
shift to some other DHCP server in future? Also, in case the DHCP server
doesn't return the IP address type and/or prefix, in that case, should these
values be NULL, when returned to the user?
