    • Size scope appropriately (consider 20-30% growth)
    • Document IP allocation strategy
  1. Lease
    • Desktop/laptop networks: 8-24 hours
    • Guest networks: 1-2 hours
    • Static workstations: 3-8 days
  1. Availability
    • Configure DHCP failover for redundancy
    • Monitor DHCP server health regularly
