A DHCP Discover packet is similar to the analogy above. When a device needs to obtain an IP address, it sends the DHCP Discover packet to the broadcast IP address Packets sent to this IP address are received by all hosts on the network, and is used in this case to try and find the DHCP server.

Who is the DHCP Discover sent to?

The client discovers a DHCP server by broadcasting a discover message to the limited broadcast address (255.255. 255.255) on the local subnet. If a router is present and configured to behave as a BOOTP relay agent, the request is passed to other DHCP servers on different subnets.

Should DHCP be on or off?

The Premise Behind Disabling DHCP The idea is that most devices don’t anticipate the need for a static IP address and try to request an IP from the router. If the router doesn’t have DHCP enabled, it will ignore that request and the device won’t connect.

What DHCP is used for?

Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway.

What happens if I disable DHCP?

Once you find the DHCP settings, there should be a checkbox or option to enable/disable the server (see Figure 5). Uncheck the appropriate option and save the settings. Then from now on, users won’t be able to access the network or Internet until they’ve configured a static IP on their computer.

What happens if DHCP is not enabled?

In short, Dynamic Host Configuration Protocol (DHCP) can automatically assign and manage IP address for your device. DHCP is not enabled means your wireless access point is not running as a DHCP server, then it will not give an IP address, and you can’t access to the Internet.
