Understanding IPV6 Part 2

[Topnikko]

Nice! But you keep refering to Hextets as Octets. Octets don't exist in IPv6.

@Topnikko Yeah I was sick as hell when making that video and old habits die hard. Cheers!

@Topnikko if you break an ip, ipv4 or ipv6, into binary it's still 8 bits at a time.. at least that's what we are being taught in CCNA class... are we getting taught wrong?? also makes me glad I gota hex lesson in highschool.

[bufo333]

@Darksunbird you would convert hex into binary the same as you would with ipv4,

[bufo333]

@Topnikko yes old habits die hard!!!

Very sweet series, thanks!

Thats a good question. We should not have an issue with mac addresses. But if we did run out of them it wouldn't matter because mac addresses are only locally significant. As soon as your packet hits the router. The router takes the layer 3 packet and adds a new layer 2 frame, replacing your mac address with its mac address and discards the original mac address. So unless we had 2^32 computers on a single layer 2 segment, I think we will be ok.

@bufo333 Well when we run out of MAC addresses, I always heard that they'd start being reused and recycled.

Although, I never understood how, because its possible (although extremely rare) that two devices with identical MAC addresses be deployed on the same layer 2 segment. In that scenario you'd run into problems. I'd be interested to see how manufacturers start to recycle MAC addresses, to ensure that this doesn't happen.

@mierdin21 many manufacturer already reuses old MAC addresses. I have even been biten by that one time.

But basicly, each manufacturer get a range of MAC addresses, and when they have runned out och addresses, they just start from beginning again. And the prob. that you get the same MAC address in the same LAN is quite low. And that is the only then it will be a problem. If you get the same address, you can usually program your device with another MAC address.
