We will be talking about the ping comment and traceroute comment so far, shipping companies use it
to test the connection between the source and destination, and Presswood comment uses it to define
to show us the actual.
But the packets are going from source to destination.
And let's see first come.
OK.
Let me show you the IP address of my.
So we need to type of conflict to get that information.
So this is the Petraeus is my wife and it has been I responded to that one.
You should not.
So now I can subpoena Google dot com.
So we need to bring the Google dot com and you can see Google dot com does not have any IP address and
it will be resolved by a server.
So first, being guru.com and first thing my computer did is it received the IP address from my ISP
server.
We have already seen how business works in that way.
We have got the good outcomes site IP address.
Is this fun?
And I'm going to show you not the computers are Google.
OK, so 64 bytes from this name server and you can see ICMP sequence one.
This is the sequence is the order of packet.
You are sending these off to a packet you sent and this is the second.
This is the third and this is the fourth.
And this is called Time to do and time two for one participant for that one milliseconds.
So this bank can vary within one second and it is a 64 waits to see what from this name server and just
the IP address.
This one.
And here you can see the company statistics track report from the spring and fall package has been transmitted.
You can see this is one package and this is one.
This one.
And these are four packets transported and we have received four.
So there is zero percent lost back across.
And the total time is around, it's like three seconds, right?
OK, now we have some options for this Pinkman you can set payment.
Right to do.
And it will wait for two seconds for sending Etchberger.
For shipping minus eight to guru.com now for Spicket has been sent and to the second bagrut has been
sent.
You can see this delay between the time of two seconds because we have to find the item.
So this is one option.
And another option is you can just switch for a number of packets you need to send waiting for it to
send infinitely.
And if I say five packets.
And the C stands for count.
So after five that I did not press the controls.
You see, it has automatically stopped because we have said that after count of packets, you just stop
the ping.
And you can see Finback, a transmitter with you.
So what if I been to a server, which is not there certainly outcome.
So of course, this is not the.
OK, OK.
I don't know if these are going on right now, OK, that's.
OK, we need to set protocol.
Good name or service, not not that means.
The Dina's name for this dot or has not been found.
That's what it was written said was not for.
So that's being.
Thing and not a dirty dirty, which is a private IP address for the IP address IP range.
And this is a private IP address for the class and it has not been assigned to any of my computers that
until now, since we have given you can also get IP address and it's just ping this IP address with
the 56 Bitauto.
Let's see what happens.
So this ping utility keeps on trying for getting the marketers to this dirty dirty.
And it is because there is no IP address, no computer, this IP address, free press control.
See, you can see 24 packets has been transferred.
What that means are these packets are lost during the transmission because we do not get any acknowledgement.
That's why 100 percent back across time is this much and this ping come in.
These messages are from ICMP protocol.
These are the Internet control protocols.
And this protocol just sends the wrong message when there is no service or no host, not phone or something
like that.
So another comment we are going to use.
Traceroute, Traceroute.
It's very simple.
Come on, Traceroute and Google dot com.
OK, this traceroute traces the path from your computer to the guru.com.
So I want to send if I want to send a packet for you to go to my gate, which is the router I have already
seen.
So you shown in the previous year, this is my tippling IP address and this is the gate with the first
thing your computer does is it will send the packet to default gateway because there is this Google
that comes IP address does not exist on your network.
That's why this computer sends 230 for the gateway, which is Maroota.
And then this router, since the data to the nearest road that knows about this guru.com and this is
not perpendicular to six, and these are the other devices which are in the path between our computer
and finally guru.com computer.
And you can see there are 30 hops, Max, and these are only nine hops.
Hops means the intermediate distance between the source and destination are hops.
So finally, we have got the proof from this IP address, which is this one guru.com.
And the intermediate hops are one, two, three, four, five, six, seven, eight.
You can just say there are eight hops.
If you include the router, you can see nine hops.
OK, that's all you need to know about this spring and summer, so the government is using to test the
accountability between you and their definition computers and Traceroute is precious.
Are the parts are there to assist in between your source and destination?
