3. IPv6 Address Types

[@touchdownbroncos]

Fun little experiment I did. I have 2 LAN adaptors on both my machines. I run all IPV6 traffic thru one adaptor, and the IPV4 thru the other on each machine. Not only does it provide a bit of load balancing, it gives you an idea of how much IPV6 is TRULY used as of today. For me and my network, IPV6 is double the traffic of IPV4. This is reflected in the amount of data each adaptor handles.

I'm about to finish my network security class and this part was very important to me to understand. Thank you!

[@SAM15BFR]

Thank you so much. Your videos are always so helpful.

[@PETAJOULE543]

Good video explaining ipv6 address such as unicast, multicast, and anycast

[@hammadiazaiez9337]

GREAT VIDEO! just a small info you said in 1:40 : start with 002 and /3 means 3 bits 001 are fixed , yup but the hex has 4 bits so it can 0010 =2 or 0011 which is 3 , so they can start with 2000 until 3FFF , thanks

the video is great but you need to add a note for the real unique-local prefix FC00::/7

I know Im kinda off topic but does anyone know a good site to stream newly released tv shows online ?

[@merrickgustavo6502]

@Joel Eugene Try FlixZone. You can find it on google =)

[@tysonchris848]

@Merrick Gustavo definitely, been using Flixzone for since april myself =)

[@joeleugene9735]

@Merrick Gustavo Thank you, I signed up and it seems to work =) I appreciate it!

[@merrickgustavo6502]

@Joel Eugene You are welcome :)

Great video! thanks

[@hadran1567]

Thanks a lot 👌👍❤️

[@markganus1085]

unique local is an IPv6 address that provides communication between subnets and cannot route on the Internet

[@davidandrew447]

fantastic video

great explanation, Thank u

nice job brow!

[@NeerajSharma-ob8wf]

Unique Local starts with fc00::/7, defined in RFC 4193

[@hugoboy23]

I have the same information for unique local address....fc00::/7

[@theblablaify]

same

[@astrotech9663]

FC and FD are both unique local addresses, the 8th bit is set to a 1 to indicate that its local

[@JivanPal]

Per RFC4193: • in `fc00::/7` addresses, the 8th bit of the address (called the "L bit" in the RFC) is set to `1` to indicate that the address is locally assigned. This class of addresses is the `fd00::/8` subnet. • the class of addresses where the L bit is set to `0` (the `fc00::/8` subnet) is currently undefined. Quote from RFC4193, §3.2: "This document defines a specific local method to allocate Global IDs, indicated by setting the L bit to 1. Another method, indicated by clearing the L bit, may be defined later. Apart from the allocation method, all Local IPv6 addresses behave and are treated identically."

Great video

[@kathee-987]

Thank you 🫶🏼

[@Krishna_Singh_2111]

i am really surprised that literally no one got the doubt that what those (/3) and (/8) are!!!

[@giancarlochaparro4519]

What is the multicast range for ipv6 addresses?

[@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?

Where did 10 come from?

[@dariobm1528]

I just wanted an IP cause i already configured it

[@ul3m8]

If FE80::/10 is a '/10', that means that the link-local addresses all start with 'FE8_' but that the last digit in the first colon can change? Because the first colon is 16 bits and it is a /10? or am I wrong somewhere?

[@JivanPal]

`fe80::/10` actually refers to more addresses than that. That subnet is equivalent to the set of addresses that begin with `fe8`, `fe9`, `fea`, or `feb`. *_Explanation:_*_ Each hexadecimal digit represents a nibble (4 bits), and the fact that this is a `/10` means that the first 10 bits of the address are fixed. As such, the `fe`, which represents the first 8 bits, is fixed; and the first 2 bits of the `8` are fixed. Converting hex to binary, `8` is `1000`, so this nibble can be `1000`, `1001`, `1010`, or `1011`, which correspond to hexadecimal `8`, `9`, `a`, and `b`, respectively._ Despite this, RFC4291 (specifically, §2.5.6) specifies that the bit-pattern for an IPv6 link-local address is `1111 1110 10`, followed by 54 zeroes, followed by a 64-bit interface ID. In practice, this means that all IPv6 link-local addresses are of the form `fe80::WWWW:XXXX:YYYY:ZZZZ` (that is, `fe80::/64` is precisely the set of link-local addresses), and all other addresses beginning with `fe8`, `fe9`, `fea`, or `feb` remain unused for now.

[@nessd665]

anycast is routable then?

[@ausnetting]

Yes. You can do the same with IPv4 though with any Unicast address. For example the Verizon DNS servers (4.2.2.1, 4.2.2.2) are used in multiple regions and you're routed to the closest one when you send a DNS request to either of those addresses.

[@rakesh4a1]

Thanks a lot for covering information about ip addresses. Have a doubt btw link-local and unique-local. One of the statements says that unique-local is unique within the network. Does this mean that link-local is not unique? link-local addresses are unique and verified with neighboring nodes within the network. kzbin.info/www/bejne/lYTVm6Oeltljrdk 04:10

Unique = Site local start with, ex. FECO::/64?
