IPv6 Addresses Explained | Cisco CCNA 200-301

[@swiatlowiekuiste]

People in year 2100: haha remember when they thought ip6 addresses will be enough?

[@waynezahra9213]

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 💪🔥

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.

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

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.

3:06 the main edge of IPv6 vs IPv4 is it has "lettuce"

[@Certbros]

😂😂 FFS. British accent strikes again!

[@PatrickStaight]

1:40 In my current place in learning about IPv6 I'm thinking of it as as having 2 exbibytes of roughting space, with each rought having 2 exbibytes of addresses. I'm pretty sure IPv6 roughing is not that naive. I'll watch the rest of the video to find out. I'm interested in IPv6 exclusive shared hosting systems. With Google Domains shut down and with other name registrars making custom nameservers harder, I think IPv6 is the future of the sub-VPS end of the internet. I want a shared hosting server with thousands of static IPv6 addresses. I imagine they won't all be sequential. Can roughing tables support address hash entries or do they only support sequential blocks of addresses?

[@aryanrh2762]

Awesome explained!

[@yayinkenrick2715]

Love ur vids and explaination especially the routing protocols really helped to understand it. Do you plan to release full course on udemy or other platform soon?

[@Certbros]

Thanks Yayin! Great to hear you're finding them useful. The plan is to launch it on my own site using teachable which is a popular course platform. I'm not quite there yet so it's not 100% decided.

[@yayinkenrick2715]

@@Certbros thats great to hear. Any timeline when it will be available? You already have lots of already created resources from youtube. Have you already planned the syllabus topics?

I'm hoping to release it later this year. I'll probably do a discounted pre release ASAP. If that interests you then make sure to register your interest (link in the description). Great to hear your enjoying the videos. You're right, they do take a lot of time to make but I'm getting there!

[@TheFinFriends]

Very helpful ! Very well explained !

[@davidbrown9981]

Question re: Global Unicast. You say that it starts with either a 2 or a 3 but also that it is a /3. Don't you need the first 4 bits to be able to make the number "3", eg 0011, so shouldn't it be a /4 mask ?

[@Certbros]

Great question David! The 2000::/3 prefix means that the first 3 bits (001) can't be changed. That said, the last bit can be changed as part of remaining address. So it can either be 0010 (2) or 0011 (3). Hope this helps.

[@davidbrown9981]

[@brewandrew]

You removed the 0 from the "0db8" so it became "db8" but how does the computer know if the missing 0 comes at the beginning or at the end?

[@locrieth]

The 0 is always the leading number, so it will always be at the start of the Hextet

Guy is absolutely correct. Hopefully this helped.

[@petew8279]

What does it mean when My phone shows Me 2 ipv6 ?

[@Stefan_Dragancev]

Hello, why we need local link address? What would happen if the computer don’t have local link address? Why computers don’t use MAC address instead?

[@ximalas]

Its main purpose is to give you an unique address to be used locally, i.e. on your VLAN. It's handy when using the built in autoconfiguration of IPv6. See ICMPv6 Neighbor Discovery for more information. It's a topic in its own right. Also, to answer your last question, IPv4 and IPv6 tries to be independent of the lower layers. Nevertheless, we need things like ARP, and luckily the designers of IPv6 had the common sense to include the IPv6 equivalent of ARP directly in the ICMPv6 protocol.

[@VaupellGaming]

Were using IPv6 at work, and it's funny to see the new IP's showing up with net slash as Percent sign instead of forward slash in powershell it shows up as example.. fe80:......:216%13

[@ximalas]

This is an interface index local to your system. IPv6 presented some bugs for multihomed systems. Afterall, the link-local prefix is identical on every interface. When we need to send link-local traffic to a certain address on a certain interface, we can select said interface by specifying the interface index at the end of the address.

[@zt1788]

I'm confused on one point. In the example, it's mentioned that ,,,:0bd8:,,, could be shortened to ,,:bd8:,,, My question is, how does the system know in which position to place the 0 when decoding the short form of the address?

[@LongThanh-iv6ih]

we can only short the 0db8 to bd8 when the zero is the 1st number, this won't work in the case of bd08 or b0d8 so system will know where to put the 0 when decoding the ip.

[@raghunj2621]

Although not exclusively indicated, the video shows cell phone. Note the cell phone DOES NOT HAVE an IP address. Instead it used IMSI, which is only and identity but over the air uses TMSI which changes often. Note that cellular security is mainly at physical and Layer-2 (baseband) unlike wireline security schemes. Therefore the number of devices on IPv6 applies to other devices that need an IP address, but not the cell phone.

[@theother9941]

instead of using ":" (which is already used to separate hextets) to represent 0000:0000, why not use a different symbol? That way it could be used multiple times without ambiguity? What am I missing here?

[@antonfernando8409]

nice. how do you ssh to an ipv6 address, and I guess ssh-keys will be the same.

[@danielruzicka3858]

What about all the addresses that do not start like Global unicast, Anycast, Unique local, Link-local, Multicast ? Are they used somehow or they are assigned to some privat companies ? special purposes ? or they are unassigned yet and we will decide their faith in future ?

[@deadduck8307]

Why is the 0 in 192.168.32.127 not there, whereas 192.168.302.127 needs its 0? Same answer here... the 0s in 2001 are not preceding 0s, and thus carry digit place value significance. If we omitted them, the 2001, 0021, and 0201 would all be the same...
