TOPIC: TCP/IP Protocols
AIM: How does DHCP work?
NOTE:
1) At the end of the period, leave your computer on the desktop screen, put the keyboard on top of the monitor and push in your chair.
H.W. # 69:
1) What are some settings that are configured by DHCP?
2) What are the benefits of using DHCP over static assignment and configuration of TCP/IP information
DO NOW:
What four settings have we discussed that can be set in the
TCP/IP properties?
Depending on which of these had to change, we would have to
go to every machine and reset these TCP/IP properties.
Fortunately for us, there is something called Dynamic Host
Configuration
Protocol
(DHCP).
Go
to
www.techweb.com/encyclopedia and look up DHCP. What is
DHCP?

Assignment #1:
To run DHCP, you’ll need a computer running DHCP server software. What is
is the IP address of the computer running our DHCP server software?
Assignment #2:
Go to http://www.windowsnetworking.com/articles_tutorials/w2kdhcpc.html and
read how to set up a DHCP server using Windows 2000 Server. After reading
how to set up a DHCP server using Windows 2000 Server, answer the following
questions:
A) What are some devices that are traditionally
given static IP addresses as opposed dynamic
IP addresses?
B) What is a DHCP scope?
C) What is a DHCP lease?
2
D) Checking your own computer. When did you obtain the lease for
your IP address?
When does the lease for your IP address expire?
Assignment #3:
Any Windows 98 and later Windows client that is configured for DHCP,
but unable to access a DHCP server will always default to a special IP
address starting with 169.254. This is the APIPA address. Look up
APIPA at www.techweb.com/encyclopedia . What is APIPA?
Under what circumstances might you have to renew or release you IP address
information?
