Tracks
Servers
Networking
Prerequisites
Basic understanding of TCP /IP
TCP/IP and Subnet Masking
Purpose of Class
This class teaches students what DCHP is and the core concepts of Dynamic Host Control Protocol.
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

Eli does love what he does, and enjoys teaching it with passion which makes the people watching truly enjoy and learn a lot. Thank you Eli, you are just great
this has being on youtube from 2013 and now its 2017...thanks so much your a life saver ..... please continue to do what your doing ELI
6:30 The true handwriting of an IT professional, I love it.
Anyway, thanks for making this video. I have a test comming up in 3 days and this helped me a lot. I am really greatuul!
Than you Eli Network Master, tomorrow is my Network DHCP knowledge presentation. I hope i can preform well with all the information given by you. Thank you so much
Hes the best
Thanks Eli, another clear explanation! You're providing a great service for IT students all over the world. Keep it up!
Baddest, baldest IT guy on the planet. Thanks Eli.
😁 typical bald IT guy. But then he experienced a burnout. Again typical of IT guys.
@@SiddharthSinghFiery69 what happened after the burnout?
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.

+sdrtyrty rtyuty you are a disgrace
+Willy Durf I admire the fact that you can appreciate help and humbly thank someone for it with such grace. You are a role model.
+sdrtyrty rtyuty practise what you preach...

If I did, I wouldn't be able to respond to your comment ;)
Well I still think you are quite an interesting person and you seem to post quite a fun response or quirky debatable agenda. It quite perks my interest. I hope to cross your intellectual path on another topic
Thanks eli, you have made my university life easier
Eli is the best of best
thanks for your explanation!
you're a star Eli. you helped me a lot. for free. you are my tutorial guru. thank you.
After reading all your comments on this video I now need to watch it and then watch a bunch of your other videos. It may help me explain things to normal people.
Wow I can listen him at 2X speed and still understand every word even though I have never seen an English native in my life, just awesome that's what people should listen to learn English)))))))))))))
Eli I'm in school right now learning networking and your videos are very helpful thank you!!!!!!
I like his presentation!! He covers it very clear and to the point.
I learned so much stuff about networks from your videos. it's just awesome how you explain this things.
My great grandfather invented peanut butter and your video tutorials are a great invention also.
Man you're videos jus leave me speechless,
I have my exam tomorrow and all I've been upto is seeing you're videos
I don't even feel like I'm studying
It's so much more FUN :)
You make Linux much more FUN to me atleast !
Keep it up you are doing something AWESOME and you definitely are unbeatable at it (y)
God bless you, brother, thank you so much!
man I love your videos really helping me out in school they give me a short paragraph and your videos help me understand them a lot more
Thank you Eli! You're classes are very educational and proffesional :D
Eli should make a Book of Eli! :)
Too info for Free
You explain this better than my professor. Thank you so much!
Makes it seem very simple and logical - who has been hiding this guy?
Amazingly easy to follow videos. Soaking up some knowledge before continuing to further my technology career! Thanks Eli
Thanks Eli unbelievably lovely and very articulated as usual .Bless you
Thank you and as athank back i subscribed. You explain it plain and simple and much better to understand than what sometimes is written books
Thanks for the DHCP, all set to follow your Server 2012 course.
Set up a vituralbox environment with Server 2012 and both a Win7 and Win8 client using pfsene to isolate the network.
Wish I had the metal for a real test lab, it is the best way to go.
Thanks Eli..Your explanations are so good. Thanks once more
thank you, very clear explanation.
I watched several of your videos, have been very helpful in clarifying a lot of matters, thank you
Love your videos Eli! Just wanting to send some encouragement your way to keep it up and to consider sticking to the actual whiteboard, it's so much better because you're able to write faster and clearer and we can see your body language while you work.
your better than my teachers explanations Thank you so much man! :)
well Sir, i enjoy watching all off your stuff.
Eli => Baltimore finest
Thank you so much! I just watched 5 minutes but understood so much like attending a 50-minute courseXDDDD
That is really great, clear and very helpful.
Thank you very much Mr. Eli
Hey Eli you are a really good trainer, your explanation skill is just awesome it is really very helpful for me to learn about that particular topics....
please send me all your videos....
Thanks to upload this video and send me your all videos of CCNA please....
Helps me freshen up everything... thanks Eli
Hello Eli, Talking about the DHCP is good but it would be better to demonstrate it in series of commands. Seeing is Believing. Show the necessary interface and related commands.
Very good video, very well explained will definitely sub!
Clear and right to the point. Thanks
Very well explained.Even a novice like me got some insight into this subject.
it totally depends on what you are up to.. main thing is to understand what tasks need to be done. If it is running cmd,than you can use old celeron powered laptop.
Thank you Eli Network Master
The best informative video that i have seen u rock Eli
Much better than just reading this boring MOAC book.
Eli is the best!
Thanks a tonn !!!!!!!!!! Superb videos.
I suggest you to explain on white board because you can hold attention and makes a feel " lecture in room in person ".....
Thank you a lot for your efforts. Looking forward for Windows 2012 DNS class.
Eli, you are awesome! Thank you!
I love this guy!
I like your old skool whiteboard better lol. But great bid as always, so helpful
Excellent video. Thanks a lot.
Hi Eli,
You have explained a concept in a very nice way. :)

Great explanations, thank you !
Thank You Eli I'm gonna Use this points in presentation
I like what you did with the whiteboard
Yes. This should be part of a playlist. Check his channel.
Thanks Eli.
simply awesome.. thank u
Amazing! You are outstanding at explaining this.

Need some videos on SSCM,WSUS,SUS, your video are easy to understand..Thank you
Well explained,thank you!
i'm in love with the shape of you Eli :)
best tuotor ever
You're awesome! Thank you for sharing your knowledge =)
Hi all, just wanted to share, because it wasn’t explained in this video and it took me a while to find the answer that the broadcast address for DHCP purposes is always 255.255.255.255, so that’s how a new host knows what IP to use for broadcasting. (At least that’s how I understood it from this thread ➡️ community.cisco.com/t5/other-network-architecture/broadcast-address-and-255-255-255-255/td-p/317056 )
thanks for the lesson, it have been a long wait
Awesome video!
Very clear!!! Thanks a lot for the awesome video!
How do I switch my DHCP server for ONLY my computer? My ISP forces me to use theirs. But I want to make the computer only use the DHCP of my active directory. How Do I do that?
Thanks Eli
Awesome. Thank you.
THX so much Eli
very helpful ....Thanks
Thanks Eli, you rock mate!!
really helpful, thanks, Eli.
ITs Good video for beginners.
very very helpful
Good explanation but very basic for beginners. No setup information. Was looking for Cisco commands for SLAAC Funny, while watching the video I noticed a bug crawling on his desk (left side) at 21:30. Waiting or it to crawl up his arm. LOL
Hi Eli, got few questions on DHCP. In all my questions I am trying to relate
to On Field implementation, so questions also might be wrong
1. How the DHCP Packet travel to the ISP ? how means first it need to bypass the local gateway, and local gateway will be acting as a Relay ( if my understanding is correct ), aftwards how ( DSLAM or many routers not sure) the packet will reach to the ISP Router.
Basically the question here is what is common/best topology is used ( keeping in mind factor like firewall/hacking)
can you give a example of any ISP vender of your country and as a user how you really connect. As in between user and ISP you can get different devices of differnt vendors...
2. I saw a video of a firewall (linksys), where the firewall was also capable of providing an IP as DHCP was running. How the IP provided by that firewall and ISP differs ?
is the IP given by firewall is routable ? if routable is it because of the conecpt of NAT ? if because of NAT will there be any impact on network ?
3. Any device which is capable of responding of your request is called a server. Question here is, if a ISP is running a DHCP, does is have to be a edge router ?
Can you please post a video of edge and core router. It would be really great.
Thank for posting those beautiful videos :)
Great explanation buddy thanks
Thanks, shorty!
great stuff
super info sir
Awesome, I kinda like the regular white board though
nice work
Great lesson, thanks
Digital whiteboard? Moving up in the world.
Eli, would you be discussing clustering as well in the future videos? Your teaching technique is remarkable!
thank you so much..
Great video, thanks!
Thanks for the Video Sir. I am new to Networking but I have heard that Default gateway is the actually a Router and It assighns the IP address to all the devices connected to the Network(Home Network) Then what is the kind of IP address that DHCP provides and as Default gateway is your Router then how DHCP assighn the Default Gateway. I am sorry If I sound dumb but please explain. It will be a big help.
Thanks
18:10 Noobie question but wouldn't that be a reason to assign DHCP servers static IP addresses? So no computer with a different IP than the one assigned could pretend to be the DHCP server? And then assign the client computers to use a static IP for DHCP in network properties > IPV4 properties? Or maybe that wouldn't work because there could be more than one DHCP server and there's only 1 blank for a static?
this is what i was exactly looking for (Y) thanks .
Really thanx Eli you are amazing :)
great work man ,, keep and keep going :) ..and we follow you
I have leared something today :) thanks a lot to you....
I'm becoming of your Fans Eli...
Wondering how much cost do I pay for tuition fee tutorial out there. You are amazing! Thank you very much. :)

Hello Eli , I am following your postings and they are all very informative , in this particular video how does the Client like a personal laptop know the IP address of the DHCP server. So for instance I bring in a tab home and connect to a wireless network , I connect to the SSID listed in the list of wireless networks is it configured in the router i got from my ISP ?
the client do sth called broadcast and it asks to every local network for the ip address then the DHCP respond to it by saying "hey this is ur ip address"thats it
