MAC address

Exactly right.

A Layer 2 switch forwards frames by MAC address inside one broadcast domain.

A Layer 3 switch also routes packets by IP address between subnets.

One is about whether you can talk to the device.

It isn't.

It does the baseline job, and the baseline job is real.

It learns MAC addresses and forwards frames out the correct port.

That's the whole function of a switch.

And the reason I say that is because each study led on to new scientific questions.

So by the end of the 2024 study, when we knew this product was amazing at removing all these toxins from people's bodies, um, then the question came about, well, if we're removing the graphene oxide, which had been talked about in many scientific studies to be part of a conductive material when combined with potentially semiconductor material, you know, um, synthetic silicon in a lot of, uh, research studies and nanotechnology, the question was, well, could this be part of why people are emitting MAC addresses? So our study after that became looking at the humans emitting a MAC address, which sounds crazy, but there had been two previous studies done on this.

Uh, a French, uh, ex...

It was called the French Experiment study, where there was 30 test subjects, where they found that everyone who had taken the COVID shot were emitting a MAC address.

And there was also a, a Mexican study with Dr. Chavez, who took people out into the middle of nowhere in a technology-free environment, and these test subjects again were emitting a MAC address.

Um, I think it was, um, some of the people hadn't taken the shot, but some people had PCR tests.

So we thought, well, if we're removing potentially part of the technology that could be pa- part of why people are emitting MAC addresses, could we actually dec- decipher whether removing the graphene oxide could be, um, helping people to disengage as a MAC address? Uh, because we know that there's talk about h- Homo sapien merging now or turning into Homo borg genesis with this, uh, nanotechnology as part of this transhuman agenda.

So this is where our work kind of went into a slightly new area, [chuckles] where we're looking at these signals coming off humans.

EVPN as a control plane can run over an MPLS data plane instead of VXLAN.

You get EVPN's BGP-based MAC, IP learning and multi-tenancy model, but forwarding uses MPLS labels instead of VXLAN encapsulation.

This is common in SP telco DC interconnect designs that want EVPN's operational model with MPLS's overhead and TE characteristics.

Text this decouples the which overlay control plane decision from the which encapsulation decision.

Since the group-based tags are standards-based attribute value pairs, every single radius server can send them back.

The other part is, you know, you statically assign them IP, you know, MAC and so on and so forth.

The policies themselves.

I

It is a destination.

It could just be statically tagged to say this is this is a group, it's specifically a tag function.

So just to clarify, I can build tag policies around things like IP address, MAC address, or role, like this is an employee, this is a security camera, this is, I don't know, an MRI machine.

Yes, absolutely.

... or over the weekend on episode 63 on Link Layer Discovery Protocol.

And Jeff said for this Well Actually, he's not an expert and had to do some looking to find this information, but the destination MAC address used by LLDP seems to be defined as a sort of scoping mechanism-

Mm

... particularly around the idea of provider bridging.

It wasn't one of those kind of things.

But he did find some, some good information there.

D- th- this is where we were talking about the different MAC addresses that are used in an LLDP frame, and you and I were like, "It could end in 00 or 03 or 0e, that MAC address."

Yes.

when I do a discovery, when I'm doing an assessment, like I want the switch configurations, I want the firewall configuration, but I don't want just the switch configuration.

I want them to do show CDP neighbors, talking Cisco iOS, right? Show Mac address table.

Like you can map your network with your switches because it knows the Mac addresses that are plugged into it and the ones that are adjacent to it and the switches.

Like I can do a 80 to 90% map of your network running a few commands on your switches.

Wow.

And then doing a Mac address search on Wireshark's OUI database.

And I basically have a really good list of here's the Macs, the types of devices they are, and the ports they're plugged into in your network.

Absolutely.

How did the device identifiers in this Apple Watch match the Apple Watch activity found in the Apple Health database from Caleb Flynn's iPhone?

I found the, uh, Apple Watch MAC address, which corresponded to the MAC address, uh, for this watch in the phone.

What was the model of the Apple Watch you examined?

It was an Apple Watch Series Nine with, uh, GPS and LTE.

What internal hardware model identifier did you find for the Apple Watch?

I found what's called the, um, MAC address, and it also was referred to as an Apple Watch Series Nine.

What was the source name displayed in the health application for that Apple Watch?

It's Al- Caleb's Apple Watch.

I found two names for the same device.

One was, uh, Caleb's AirPods, and the other one were AirPods 4, parentheses A and C.

What is a MAC address?

A MAC address is, uh, like a serial number to a device.
