What does DHCP Discover mean?
During the boot process, a client computer that is configured as a DHCP client sends out a broadcast packet called “DHCP Discovery”. This Discover packet contains the client’s computer name and Media Access Control (MAC) address so the DHCP servers can respond to it.
Who sent DHCP discover?
The DHCP server receives the broadcast DHCP Discover message and responds by sending a DHCP Offer message. The DHCP Offer message includes an IP address that the client can use. Like the DHCP Discover message, the DHCP Offer message is sent to the broadcast address.
How does a computer find a DHCP server?
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.
What does network DHCP mean?
Dynamic Host Configuration Protocol
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 are the disadvantages of DHCP?
Disadvantages of DHCP
- Tracing internet activity may be difficult as the same machine may have two or more different IP addresses over a period of time.
- Not having a static IP means computers with DHCP cannot be used as servers as their IP will change.
Which is a message of DHCP?
DHCP uses the client/server model. A DHCP client sends a message to a DHCP server to request configuration parameters, such as the IP address, subnet mask, and default gateway address. The DHCP server responds with a message carrying the requested configuration parameters.
Why to use DHCP?
Short for Dynamic Host Configuration Protocol, DHCP is a protocol used to assign an IP address to a computer or device connected to a network automatically. Routers, switches, or servers that use DHCP to assign addresses to other computers can make setup and management easier for the network administrator.
What does DHCP stand for?

What is my DHCP range?
In the usual case you’ll have a router that uses DHCP to hand out IP addresses to all the machines on the network. Just log into the router and look at the range of IP addresses it hands out. Typically is your IP is 192.168.0.15 then the range is probably 192.168.0.1-254
