2016-08-22 14:56:34 Paolo de Rosa description Platform MAAS 2.0 Xenial Our customer is using MAAS to provide dhcp service on /30 networks, IP range has only one address reserved ad dynamic range so MAAS generates DHCP configuration correctly but it has an issue generating bind zones. For example when there is a network like 172.16.0.4/30 where 172.16.0.6 is the gateway and 172.16.0.5 is the only one IP in the dynamic range what happens is that in file /usr/lib/python3/dist-packages/provisioningserver/dns/zoneconfig.py function get_details_for_ip_range(ip_range)will be called with only one element. spanning_cidr(['172.16.0.5']) The traceback below
