Class Notes
DHCP stands for Dynamic Host Configuration Protocol
DHCP is a Server Service
Separate from DNS
Can be found in Windows Servers/ Linux/ Unix and Home or Small office Routers
DHCP Servers Assign:
Dynamic IP Addresses
Static Subnet Mask
Static Default gateway
Static Primary and Secondary DNS Servers
Scope is the pool of addresses that the DHCP server can assign from. Such as192.168.1.100 to 192.168.1.200
Lease is the length of time that the DHCP server will reserve the IP address for the client.
Clients will try to renew the lease periodically
Lease length can be manually configured on a per server basis
Reservations are IP Addresses that are reserved for systems that need Static IP Addresses
Steps for Getting an IP
DHCPDiscover -- Client Requests an IP from Any Available DHCP Server
DHCPOffer -- DHCP Servers offer IP Addresses
DHCPRequest -- Client Acknowledges which IP Address it has accepted
DHCPAck -- DHCP Server Acknowledges Client has accepted IP Address

Hello Eli,
    I have been working with computers, shall we say, when they were made with Vacuum Tubes.  Well, almost.. You seem to have this network calculus down.  I am the Break / Fix person you mentioned as yourself in another video.  I mostly did POS systems and refresh projects for Retail customers. I really never had to worry about TCP/IP because that was always handled by Level 2-3 support. 
   I have been out of work since January and recently went on an interview where I just looked plain stupid. I really should have studied this content rather than wasting my  time on Electronics.. I do have a BS in electronics but how often will I need Quadratics or Calculus to fix a computer, like NEVER..  I just wanted to thank you as in just a few days I have a better understanding of Networks and  the basics network infrastructure. I am also absorb a little SQL and Data Base fundamentals. Thanks again Eli.
    Durf.  .
