When IPv4 first came out, the people that designed it sat back in their chairs and said, “We’ve done it, we’ve created every IP address that anyone will ever need”.
How many addresses did they create? 4,294,967,296! But at the time, they couldn’t have imagined the massive explosion of devices that would require an IP address. If you think about every device you own, like a pc, laptop, smartphone, tv etc. It quickly became apparent that we would soon run out of IPv4 addresses.
The solution is to eventually move over to the new IPv6 addresses!
IPv6 provides us with 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses!
Aside from the number of addresses, IPv6 also brings a lot of other improvements that make it a lot more efficient and practical.
An IPv6 address is 128-bits long. This is what gives us a huge address space. IPv6 has 8 sections which are commonly called hextets. Each hextet is separated by a colon. It's a hexadecimal IP address, meaning it can contain both numbers and letters.
There are different types of IPv6 addresses, for different purposes.
Global Unicast
- A publicly routable address like the IPv4 public IP.
- Prefix: 2000::/3
Unique Local
- This address is like the ipv4 private IP addresses.
- Prefix: FC00::/7
Link-Local
- Automatic private IP addresses that are not routable over any network.
- Prefix: FE80::/10
Multicast
- Addresses that are sent to a group of computers or devices.
- Prefix: FF00::/8
Anycast
- Global Unicast address assigned to more than one device.
- Prefix: 2000::/3

Isn't it nice for someone to get straight to it without talking a load of nonsense? How clear and information is this video? Absolutely amazing. Thank you kindly sir. Extremely information.

[@magnontaur]

This channel is so underrated, it's absolutely insane how you guys explains things in a way that is so easily understood, where as all other channels in KZbin, your schools, your teachers absolutely fail in this department, I watch your videos and learn more in 10 minutes than I do in one week in school, you can talk about something quite complicated which requires quite some reading and understanding to do, and make it seem like it was THAT easy all along. Hats off to you guys, you're just wonderful and I'm recommending all your videos to all my classmates.

[@Certbros]

Thanks Simon. I really appreciate the kind words. Really great to hear these videos have been helpful. Good luck with your studies! You got this 💪🔥

[@alexmilliken1518]

me to my future kids: back in my day we had something called ipv4 now we use ipv10

[@Certbros]

and because it was only 32 bits, I could remember the IP address in my head 😂

[@sunburst8810]

Unlikely. Maybe in a million years

[@mr.compnet2263]

Actually ipv10 is impossible to exist, because ipv6 has 340 undecillion

The IPv6 protocol does not use header checksums. Its designers considered that the whole-packet link layer checksumming provided in protocols, such as PPP and Ethernet, combined with the use of checksums in upper layer protocols such as TCP and UDP, are sufficient.

[@itaybarok9405]

The comparasion in the global prefix was useful and goid explained. Also, I learned in more deapth about the IPv6 addresses and about how big number of values are possible in this version. You videos are helpful. Keep them and add on them more.

[@deeptir5557]

this video made it easy and simple to understand the basics of IPV6. Clarity in voice and sufficient highlighting in the video is very good. Thanks much!!!

[@jcornwall6228]

Your videos are always precise, on point and easy to assimilate. Thank you for this. Expecially the list of the types. They way you explained it, just rid it of all the complexities I picked up trying to understand it. Thank you.

god bless, I am in my first networking course and the professor doesn’t explain anything just assumes that we already know, and I have been having the hardest time understanding IPv6 but this video made it so digestible, thank you!

i've been doing a comptia course for a year now and i learned more about IPv6 in this video than my whole course, i cant thank you enough

[@Zaroth66]

For CompTIA topics professor messer is the greatest as he's organized everything specifically for the exams and made the majority of his content able to be digested in an audio only format. I've been using these videos for my CCNA whenever a topic was eluding me.

Thanks, this was pleasant to listen to, easy to follow, and really concise. I will be checking out the rest.

[@James_Knott]

One point, the host portion is always /64 on a LAN. Any other value will cause problems for SLAAC, etc. You may find longer prefixes, such as /127 on point to point links or /128 to provide an address for an interface.

[@hflx]

Very useful, I was in graduation almost 20 years ago when they start talking seriously about IPV6 and still on-going, good it makes me feel finally understand some details. Probably missing the datagram now, because I know that changed as well. Tks!
