DHCP Training

DHCP Training

Introduction of DHCP Training

The Global Online Trainings is one of the trendy online training institution in India. The global online training provides the DHCP Training we have trained all most of hundreds of students by our industrial expert’s trainer and we give training at very affordable prices that can be bear each and every student. We provide training with real-time implementations for the DHCP Training. Let’s see an outline of the course the DHCP Training it’s a Dynamic Host Configuration Protocol. In our example network, every host will have an address that starts with 192.168.1 at the center of our network it is connected to hosts the common way to assign addresses would be to give our router .1 address and to give the host .2 and .3 addresses respectively.

Learn about DHCP Training

The DHCP Training on Oct 1993 the bootstrap protocol was Introduced and it is also called BOOTP after this was an automated method could use to put IP Addresses automatically on devices without having any type of configuration

That IP Address generates basically prior to them connecting to the network. it provides an IP Addresses but not just IP Addresses that address has to be unique on the network otherwise data get conflicts on our hands and also it provides other addresses such as subnet mask the default gateway and the DNS address it has two types that are client and server.

Each computer will run a DHCP client and this will allow the computer to ask for an IP Address somewhere on the network there will be a DHCP  server

What about for four laptops maybe throw in a couple of smartphones at a tablet phone hybrid a smart TV to watch YouTube on WIFI enable printer I don’t know these things but this is mess and we need a system instead of keeping track of all those IP’s addresses manually why not let DHCP do all the math for you before

The technicalities of the algorithm that is bird’s eye view as we said above example the second PC has just joined the network at this point it doesn’t have any IP address but it wants one for the first PC our new host will send a message asking for an IP address the router will response to this request with an offer new host will accept the offer and finally the router will confirm that the IP address is assigned to the host from this point on words 192.168.1.3

 

DHCP Four Step Process:

Step1

The DHCP has two requirements one of which being a server you will need at least one DHCP server on your network but routers usually have built-in secondly every host on the network needs to run a DHCP client .there are a way to run DHCP alongside static IP addresses in your network but it’s not overcomplicated things right

Here our trusty old network again we router set .1 and we have a host setup at .2 let’s consider when a new host appears step one of the process is the DHCP discover step this is where the host search for any available DHCP server to get an address from since the host does not know where our DHCP server is it will just send out a discovery request to every on the network this is called broadcasting to put it in human language the new machine ask everyone for an address since our new host does not yet have an IP address the sender field of this packet will be set to 0.

The receiver field will be set to 4 times 255 which will cause the packet to be broadcast over the current network one last thing about UDP port 68 is reserved for DHCP clients UDP port 67 on other hands is reserved for DHCP server

Step 2

The step two involves the server’s offering an IP address to the new host the way they do this broadcasting their offered to every on the current network the reason this information to everyone is that they don’t know where to find the new host a typical DHCP offer message this address for that amount of time the center will be the DHCP server and the receiver will again be the broadcast address

Note how the ports were flipped so the sender is the UDP port 67 which is the server post and the receiver is port 68 which is the client port.

Step3DHCP Server

At this point the host has received at least one offer for an address and now it gets to pick which one at once after done so it will send out a DHCP request message everyone on the network once again this is a broadcast and in this message it will say which address it picked with this DHCP request message the host expresses its intention to accept a specific offer. The host wants to claim 192.168.1.3 for 3600 seconds which is equal to one hour.

Step4

The DHCP Training for DHCP ACK where ACK for Acknowledgement in this step the DHCP server will conform to the host that it can start using the address

 

Learn about NTP Network Time Protocol in DHCP Training

The NTP Network Time Protocol it useful for synchronizing the clocks on network devices its very essential for two reasons system messages contain timestamp that lists the time that each message is generated troubleshooting a problem that involves more than one network device is difficult when timestamps cannot be reconciled in addition authentication most often requires

 

  • synchronization because it specifies time frames for access and uses time stamp for security associations one router in the network become the NTP server all the other devices become clients and obtain their time from the server
  • The server obtains time information for a source outside the land just as your pc does a windows pc obtains its time from the website
  • NTP uses UDP/port 123 it is a slow protocol the formation of NTP associations can take a long time NTP clients are configured at least CCNA level with the single command.

 

High availability:

High availability is nothing but the network general is up and available for use as close to 100% percent of the time is possible. Earlier we discussed about the redundancy of devices and links this redundancy can help achieve high availability is not achieved by adding more hardware to the network.

Example :

In this example all the PC are in subnet 192.168.1.0/24 they all have a default gateway of 192.168.1 or the Fa 0/0 interface of router 1 if Fa 0/0 fails none of the PC’s are able to reach the network.
