Iphone Model Decoder

[Kenneth]

Ijust got this iphone12 pro and I've heard that model numbers identify whether it's a new phone or refurbished but I've never seen a model number starting with 3H? The same model number was on the back of the box aswell

At this point in time, it's highly unlikely there are any refurbished iPhone 12s around to buy. Refurbished units are sold by Apple from its own online Apple store only and currently they are not selling them there yet.

Apple has registered a ton of MAC address ranges for its products. Does anyone know whether it's feasible to reliably identify which Apple product (particularly iPad, iPod, iPhone, and MacBooks) a particular device is in network traffic via specific MAC address prefixes? In other words, is there something about the MAC address of an iPad that is distinguishable from the MAC address of a MacBook, for instance?

Over years of watching MAC addresses on networks as well as the explosion of devices on the iOS end of things, if there were a nice pattern, it would start showing in deployments with hundreds of devices.

For example, I have one Mac that has data on about 1,000 iOS devices that have been connected over time to that Mac while iPhone configuration utility was running. Looking at the data now, there are no clear patterns to help differentiate between the device types.

This also applies to Macs. Sadly, my data here is in the hundreds and not thousands presently. Yes - a string of MacBooks when ordered together will usually have sequential addresses (more so than sequential serial numbers in fact) - but over time, the iMacs seem mixed in with the Airs and the MacBook Pro.

It could be that there is some encoding present and no-one has stumbled across which bits are coded with model numbers, but a simple sort of the MAC addresses has the devices all jumbled up. Perhaps if you can find someone that runs the mobile device management software for a very large company or school district and see if they are curious enough to see if a larger data set would yield some better results for you.

I haven't seen a case where a Mac and an iOS device share the same smaller block of MAC addresses, but I can't even rule that out for you based on my experience running networks that log MAC address and are in a position to know what hardware is associated with which MAC address over the years.

My guess is the addresses are issued sequentially rather than by final destination. It would make sense to dole out parts of each region to factories that are expected to make 5 or 10 thousand devices in the next month and onle issue more once the existing addresses are consumed. If so, we might have better luck trying to bin the numbers by approximate manufacturing date rather than by where it ends up in a shipping product. Also consider on the Mac end, repairs often give a new MAC address to portables and even desktop Macs when the ethernet controller is replaced.

Bonjour is pretty talkative and generate noise for AFP, SMB, VNC, RAOP, DAAP and other services/protocols. I would suggest you to use "Bonjour Browser" then script something with Tshark (Wireshark command line) to automatize the process.

Running an agent (or profile) on each OS X and iOS devices to fetch 'sysctl hw.model' or its serial number. 'Mac Tracker' can help you tosee the different models of Mac and their spec and serial numberpattern.

Looking at the service version, port numbers [tcp 65xxx being a iphone-sync port, tcp 548 AFP (OS X)] will help you to determine OS X version and Hardware but not precisely.(You will not be able to differentiate, iPad, iPhone, and iPod, or Mac Model).

If you are simply needing to identify whether it is a Macintosh product or not you could try the this MAC address lookup service. It allows you to type in the MAC address, and it will tell you what the vendor name is. It is not likely to be helpful in terms of identifying specific vendors for programatic use, however it has worked for me in regards to finding if the machine is an Apple product.

Aside from utilizing an internal database it is not likely that you will be able to do what you are asking. If you did decide to setup an internal database it may be prudent to utilize the serial number or another unique ID available for each machine.

I was working for a worldwide known embedded computer developper/producer. As Dennis sayd (and I guess You allready known) the first three octets of six from the MAC address are for vendor's identification. Therefore u can buy adress ranges from IEEE. After them you have to guarantee as developper/vendor from your own hardware that this second part is so that the complete 6 byte MAC is entirely unique in the whole wolrd (without regarding missuse and MACspoofing for security issues later on). For lifetime of your production activity You have to guarantee that inner your 3 bytes vendor code, each code has a really unique range of adresses for second half of MAC.

We ve done this by assume a new adress (n+1) from our range n in0..16'777'215 per each MAC Vendor Adress part, where n was the last given address AND the concerning unit has succesful absolved the final function test (eg. was responding in a Ethernet test bank check).

In fact, the MAC Adress is for network layer protocoll (2nd Layer in ISO/OSI model) and used for IEE802 protocols as Ethernet,WLAN, Bluetooth and others and refers ONLY the Network Card! NOT the machine behind! So the 2nd part of MAC is nothing else then serial production number from network chipset respectively board (e.g. WLAN or bluetooth internal extention is a small smd- printed cirquit upset on the mainboard and also serviceable).

I am not aware of any official list, but you can try to compile one the way AppleSerialNumberInfo.com has done with serial numbers. You might even approach them to do it for you. A quick check of a few devices suggests it might be possible, as the MAC prefixes I looked at did vary by model.

It is very unlikely that you are dealing with MAC addresses only, you will almost definitely have an IP address for that device as well. When you do, you can fingerprint the DHCP behaviour to a level of accuracy that is quite scary. Most WiFi access point vendors do this. Visit [ ] for details on the database.

The company says that Pi-3 Mini is compact enough to run on a 2022 iPhone. In contrast, the most advanced large language models on the market are often too complex to fit even on a high-end data center graphics card.

Pi-3 Mini is based on a popular language model design known as the decoder-only Transformer architecture. A Transformer is a type of neural network that evaluates the context of a word when trying to determine its meaning. Typically, such models go about the task by analyzing the text before and after the word in question.

The decoder-only Transformer is a variation of the architecture that uses less contextual information to make decisions. Rather than evaluating the text before and after a word, it only analyzes the prose that proceeds that word. Decoder-only models are often more adept at text generation tasks than standard Transformer models and require less hardware to run.

In the paper detailing Pi-3 Mini, the researchers also previewed two larger versions of the model that have not yet been open-sourced. They feature 7 billion and 14 billion parameters. The two models scored 6% and 9% higher, respectively, than Pi-3 Mini on the MMLU test.
