What is NOT one of the ways that DHCP can be used to deliver IP addresses?

DHCP, or Dynamic Host Configuration Protocol, is primarily designed to automate the process of assigning IP addresses to devices on a network. The main methods by which DHCP delivers IP addresses include:

1. Manual Allocation: In this case, an IP address is statically assigned to a device based on the MAC address; it does not change over time and is determined by the network administrator.

2. Automatic Allocation: This method allows DHCP to assign an IP address automatically from a predefined pool, with the understanding that it will always provide that specific address to the device each time it connects to the network.

3. Dynamic Allocation: This method assigns IP addresses from a pool of addresses for a limited duration (the lease time), where devices can receive different IP addresses each time they connect to the network.

The term "Permanent" is not a recognized method of delivering IP addresses through DHCP in typical usage. While it may imply a fixed or static assignment, DHCP specifically focuses on dynamic allocations, which are inherently temporary and managed through leases. This makes "Permanent" not applicable in the context of DHCP's operational methods for delivering IP addresses.
