Root-cause analysis

Diagnosed cause

DHCP scope exhausted — lease pool fully allocated

RCA confidence86%

Above the 70% threshold — a fix can be pre-formed.

Reasoning

Pool utilization is at or above 95% while clients report lease failures, a direct exhaustion signature. Widening the scope should restore issuance.

Proposed fix

Expand DHCP scope and correct DNS

Widen the DHCP lease range on the affected VLAN to relieve pool exhaustion and reset the configured DNS servers to the network default, then verify lease issuance.

Exact calls that will run

1. Expand DHCP lease range on the appliance VLAN for network N_warehouse

PUT /networks/N_warehouse/appliance/vlans/{vlanId}

2. Reset DNS nameservers to the upstream resolver default
