we ran OUT of IP Addresses!!

Thanks to 3CX I run an entire phone system for my business and it is free for the first year on any subscription edition. And if it's hosted by 3cx you also get the first year of hosting FREE!!

This is exactly why IPv6 was invented, but IPv4 has such a hold on the Internet that few people want to convert to IPv6. Converting between the two systems isn't simple, but probably could be done. The trouble is that converting the whole Internet to IPv6 would be quite expensive and possibly even disruptive. Few companies would be willing to spend the money required.

I remember Networking Class in 1999 the instructor saying "We'll run out of IP addresses but it won't happen for a LONG time, you'll have to deal with it when I'm retired" LOL

BTW, splitting points between classes are easier to remember if you convert the numbers to binary: 1 -> 0000 0001 128 -> 1000 0000 192 -> 1100 0000 224 -> 1110 0000 240 -> 1111 0000

I got my first CCNA and sttarted to work as Net Engineer in 2006, and this was the major issue "networking people" was talking about telling ipv6 is coming to replace ipv4 in a couple of years... After 18 years we're still using ipv4

As someone who works in IT over 10 years, I obviously know about ping localhost/yourself, but I had to laugh after Chuck started to ping a weird 127.X address because I was never thinking about it that way. Awesome video!

Subnetting is probably my favorite subject in networking. It's a lot of fun. Looking forward to the IPv6 video.

14:20 I know the answer to this one. They were expecting the transistor density to translate 2x indefinitely. They weren't NOT trying to look ahead. And that means you need multiple virtual networks for software controlled loopback, I'm pretty sure it's mostly used these days for loopbacks across large sets of virtual machines.

Man I just love the way this guy teaches ! He has a way of making learning fun and exciting.

The fact you have many IOT devices at home wouldn't affect the IP address dilemma, since your router routes traffic in it's own subnet.

Nice video! I like how you simplify this topic. The only part I disagree with is how many people claim the IP shortage is due to home appliances IoT devices. 99% of those IoT have nothing to do with the IP shortage and are using a NAT local IP address off your home network and have zero impact on the world IP shortage.

There is something strangely magical about your videos/personality. It's like...I just feel better when I watch your videos. Not that I wasn't feeling great or anything, I just feel even better. Thanks man.

Thanks for the video, good vibe, very dynamic and clear ! I wish most videos were like this one hahah. It was the first video I watched and not the last one :)

When I was a NOC manager I saw a lot of DHCP issues where machines gave themselves 169 addresses. Like John pointed out in his response to my comment, these addresses are APIPA addresses and I’m sure Chuck will cover these addresses in the future. If you’re brand new to the world of IP addressing, you’re not stupid for not knowing this. It’s a large topic to learn about. Great content, as usual!

This Subnetting Series is awesome! so informative and he explained very well. great teacher, great topic!

I worked in a data center for many many years. Network Chuck is the most energized person to talk about Networking I've ever seen.

Thank for a great series of videos explaining IP addresses and subnetting in an easy to understand fashion, I've passed the link on to my team to get them up to speed. I even learned a thing or two and I've been working in IT for around 30 years and dealing with networks for the last 20 or so (I go back to the Arcnet and Novel 3.11 days!)

I love you man. I’ve wanted to learn these concepts for such a long time and I feel that I’m finally understanding all of it. All thanks to your excellent teaching methods.

Dude you're awesome. I love how positive you are and how much information you share with everyone.

Thank you so much for your videos! I have never learned something ( the basics at least) so quickly with such a well rounded understanding. something about the way that you explain things just makes my brain ooze (in the best way)
