IP Address & Subnet Mask Basics

In this video you will learn the basics of IP addresses. We will talk about the IP protocol, how an IP address looks in binary and dotted decimal, binary to dotted decimal conversion, dotted decimal to binary conversion, IP address classes, private IP address space, subnet masks, and CIDR notation

I understood more in the first 7 minutes than googling for 4 hours. Thank you.

He's a really good instructor. He made it look so easy and understandable.

[@sdek1074]

Spot on explanations. Thank you. I can't believe how many confusing videos I watched just waiting for a clear explanation of what subnet masks are!

[@aerialliz1946]

Thanks, I'm taking a basic networking course and their explanation of subnet masks left me confused. This cleared it all up. Appreciate it!

[@jevonduncan4716]

I've been looking all over, this by far this the best video

[@harmeetsingh17]

Explained in a very nice and simple way, loved it

[@RonFransen]

Thanks a lot Joe! This was very clear, it helped me understand the basics of subnet mask. Keep up the good work!

[@creaticksolutionshr8453]

Thanq for the class.. good explanation..easy to understand.

[@Kai-iq2ps]

Excellent job! Explained the concept well in a very simple way.

[@e.r.5929]

I have a feeling you're going to be my go-to guy while I work on my network management degree. Thanks for doing what you do!

[@sagarraut9455]

This Video helped me to clear my Subnet mask concept.
Thank you.

[@SaaSFamily]

awesome explanation ! simplified the concept

[@restorationtowers3097]

Great explanation. Very clear

[@Iamherp]

very well done video and really clear on the whole.
as opposed to the usual youtube tutorials out there where the guy either spends too much time talking about himself and his channel, or over-complicates the original problem

[@TheMemcon]

Awesome video!! Really breaks it down and explains it. Thanks

[@kevin2908k]

Thank you!

[@diduniAmaratungekesara]

a really nice video. well explained

[@purandarkakade9026]

simple n nice explain......

[@Grechieman]

this has really helped me, thanks :)

[@fortoday04]

But good video. I finally understand. Can you do more on "default gateway" and "port forwarding"?

[@lastcolnew4520]

like the examples thanks for the video

[@TheMrQays]

Thanks :)

[@grundlagenchemie5366]

nice video

[@positiveKani]

thanks for that

[@yogeshsoni91]

nice man..

[@danimoosakhan]

this is good but i want this document . where i get that power point document.

[@MARCELORUMANO]

Nice.video

[@thomasglanville]

Is there anywhere we can get this as a ppt or a PDF? Thanks

[@shadowlink6703]

We have you now. Watch your back.

[@akbaralam8683]

Thank a ton for this Video . i Am confused last example .. why 8.8.8.8/30 is 255.255.255.252 ?
because 32-30 = 2 and 2^2 =4 ?

[@hys10091]

2^8-2^2 =252

[@astorinonetworks]

/30 means there are 30 “network” bits, which leaves 2 “host” bits
Look at it in binary in 8 bit octets. Converting to decimal you then get 255.255.255.252

[@waqasniaz1341]

127 is a reserved for loopback or local host

[@dddiyamirza]

Thank you 4 this,sir ,can i get the ppts?pls reply

[@youngeggfu3745]

Can you explain how 220.140.100.0 /25 equals 255.255.255.128 and why
8.8.8.8 /30 equals 255.255.255.252 i don't really understand that

[@minkichawla]

nice ppt..

[@worthyvaluetime]

So true

[@Fahad96Mailam]

Can some just give me a brief summary on class e (experimental). Thx for your help 😆

[@AyushSingh19]

Can you give us the link for PPT

[@user-hj2zf3zw2p]

Class A ranges from 1 - 126 not 127

[@raghravendrareddynagareddy8906]

great

[@andrewwiggins9233]

this tutorial assumes waaaaaaaaaay too much technical knowledge. e.g. if someone who's never heard of linux before wants to learn, he will have no idea if you use terms like "Gnome, shell, BASH, terminal, kernel. ubuntu, sudo, root access. GNU" which kind of defeats the whole purpose of the tutorial.
Keep it simple for dummies.
if people don't know what an IP address or subnet mask is, when you say "IPv4" they won't be like - oh yeah i know what that means. 32 bits oh yeah that's easy. what's a packet? What's a network? what's a protocol? if they don't know what an IP address is, chances are they won't know what everythign else is either.

[@fortoday04]

"IP protocol" = Internet protocol protocol.
