An IP Policy is defined on a subnet or network definining what IPs to
exclude from allocation. From a user perspective an IP Policy looks
like the following:
{
"id": <id>,
"tenant_id": <tenant_id>,
"name": "foobar",
"subnet_ids": [] (list of uuids),
"network_ids": [] (list of uuids),
"exclude": list of dictionaries (e.g. [{"offset": -1, "length": 3}])
}
"exclude" is always required. One of "subnet_ids" or "network_ids"
is required. Only one policy is allowed per network.
A default policy is enabled on all subnets if no ip policies are
specified on that subnet or its network. This default policy is
established via JSON configuration as "default_ip_policy". The
default for "default_ip_policy" is no policy.
