Thank you! Probably the only video on YT that explains AND'ing clearly, and concisely. You deserve so much more hits that this! Keep up the amazing work
i was absolutely lost when i started reading about ANDing during the chapters... i watched this video and it is crystal clear to me now. thank you so much, i will be watching all your videos
Everytime i am entering my class i'm always shouting we're gonna nail this down we're gonna really get this going! you are amazing thanks for your help!
Well Dan as much as I don't like disrespecting my teacher, you definitely did a better job at explaining this process than my instructor did. Thanks again !
i am NOT putting my professor down at all !!!! keep that in mind.. but your awesome Dan... maybe its because i can have you repeat your lesson a few times lol. but thanks for this video!
So what is the purpose of ANDing? My instructor here taught us loosely about what it does, but never explained what it was for. Do you use it to find the subnet mask so that you can do subnetting and split the IP address in to separate segments?
dannyboiiiiii96 No the router's job is to route packets to the correct network, it uses ANDing to derive the destination network from the destination IP address and the subnet mask. That is how it finds which network to send it to.
30 means that the last 2 digits are hosts.. so the subnet mask should be 255.255.255.252 for ex. if it's 29, subnet mask will be 255.255.255.248 , for ex. if it's 28, subnet mask will be 255.255.255.240
subscribed, best tut on youtube!! also just out of curiosity, what if i have been given an IP of lets say 192.168.20.0 and a legal subnet of 10, and want to have a max of 6 computers, i have already worked out the answer and i have come up with net id: 192.168.20.128, Broatcastid: 192.168.20.192, range 192.168.20.129 - 192.168.20.191, subnetmas: 255.255.255.192, is this correct?? can someone confirm?? thanks
The purpose of an ding here , is to show us how the router figures out what the network is as he mentioned. It applies boolean logic or a truth table to figure it out.
i came to find that subnetting doesn't work. You only end up with the exact amount of hosts, the exact same amount of subnet masks, nothing changes. Nothing is isolated, and when you install the hardware, router behind router, all devices lose connectivity. You can't subnet, it's a lie. I gave up on trying to figure it out. It works out fine on paperwork, however when you install the hardware necessary to "subnet" it all fails. a router is supposed to connect a netowork to a network, however a router doesn't connect a network to a network, it breaks the connection. Where's the logic?
It is not the routers job to use the mask. When a router receives a packet there is no original mask with it. When a packet is placed on the wire, the originating device uses the mask to determine if the packet is destined for the local subnet or not.
dude.... excuse my language but mind fuck. I was stumped until this video. 255.0.0.0 255.255.0.0 255.255.255.0 netmasks are easy, its the already subnetted networks i was stumped on.. thanks Dan.
@@danscourses First off, sorry if I seem harsh. I love your videos and thank you. I understand what you are saying by “routes are masked.” I think it is more accurate to say routes in a routing table consist of a 32-bit number and a mask. To say that an address is a route and is masked is not really accurate. These two components are what define a route.
Actually, 3 components define a route. In addition to a 32-bit number and mask or prefix (Juniper calls it a prefix in their documentation), you need an exit interface. I don’t think any of them alone can be called a route.
With serial cards, like in the labs, the router in the middle uses 3 of its interfaces so 5 networks total. 3 LANs and 2 point-to-point serial networks.

Incredible CIST Instructor on TH-cam. Can't wait to see more videos.
i was absolutely lost when i started reading about ANDing during the chapters... i watched this video and it is crystal clear to me now. thank you so much, i will be watching all your videos
My textbook confused me - thanks for posting the webinars!
Everytime i am entering my class i'm always shouting we're gonna nail this down we're gonna really get this going!
you are amazing thanks for your help!
Thank you so much this really helped me out, appreciated! I didn't really understand ANDing when my teacher taught it, now I get it!
Rachel Ornelas Glad to hear it!
Well Dan as much as I don't like disrespecting my teacher, you definitely did a better job at explaining this process than my instructor did. Thanks again !
Great teacher. You da real MVP
The best channel for subnetting.. brother.. pls make videos on ipv6..
@LittlePokeDigi thanks!
i am NOT putting my professor down at all !!!! keep that in mind.. but your awesome Dan... maybe its because i can have you repeat your lesson a few times lol. but thanks for this video!
Thanks for uploading. Really helped me a lot. Bless
a 255.255.255.248 subnet mask is used for a maximum of 6 usable host ip addresses.
I recommend you watch my subnetting videos on the magic number I think that will help.
i looked up online and i got it now, I appreciated the help though.
thank you! you made it easier to understand :)
Thanks 😊.

danscourses OK, thanks.
thank you so much
it's easy to understand
Thanks. I miss 2010.
genius Dan the man
thanks alot ,
i dont know y u r using /24...idont get it can u explain
thnx :) it helped a lot
awesome thanks!
can you explain how 8.8.8.8. /30 equals 255.255.255.252? i'm just soo confused on the /30 thing but i understand the rest.
30 means that the last 2 digits are hosts.. so the subnet mask should be 255.255.255.252
for ex. if it's 29, subnet mask will be 255.255.255.248 ,
for ex. if it's 28, subnet mask will be 255.255.255.240
thnak you this les is really hulpful

Awesome to core
Hey thanks a lot!!!!
happens too often. :) thanks!
i wish you were my prof!!!!

The router definitely uses masks
All of its routes are masked

The router does not get the “the net mask”.
but that is right, the router does not receive the mask from the host, just the ip address. The routers routes are all masked...

@@Douglas_Gillette Not at all. You got me thinking that is for sure.. :)

You're missing a 0 there :)... great lessons!!
yes got
I want u to be my lecture-.-
This is classless or classful?
Classful.
If I'm not wrong 3 routers would get you 4 networks and not 5!!
With serial cards, like in the labs, the router in the middle uses 3 of its interfaces so 5 networks total. 3 LANs and 2 point-to-point serial networks.
“Router finds the network.” This phrase is absurd. Routers do not find networks.
Thumbs up if you noticed that he is left handed. lol
waste of time!!!!!!!!!!
