Python mac address random code#

Using getnode() + findall() + re() Example code The formatted MAC address is : 3e:f8:e2:8b:2c:b3 Print ('The formatted MAC address is : ', end='') # after each 2 digits, join elements of getnode(). In this example getnode() can be used to extract the MAC address of the computer. a printer or router) will remain connected to the network. A node means a point at which a computer or other device (e.g.

The main purpose of MAC address is to provide a unique hardware address or physical address for every node on a local area network (LAN) or other networks. It is always unique that means no two devices on a local network could have the same MAC addresses. I find it strange to treat it as a conglomerate of 5 8 bit and one 6 bit number.We know that the MAC address is a hardware address which means it is unique for the network card installed on our PC. After you have set the desired settings, click on the generate button. You can set the starting and ending range of the generated MAC addresses and also specify how many MAC addresses you want to generate.

Make sure you take care of both the MAC-S and MAC-L registries! ImplementationĪn EUI-48 is a 48 bit number. The Online MAC Generator was created to help with generating random MAC addresses. Therefore, your API should provide for passing in a OUI to generate an addresses for. It really only makes sense to generate a UAA within an OUI you own. I would choose the parameters such that they are 'off-by-default' ( False) and ca be 'turned on' by the caller: def random_eui48(*, multicast: bool = False, universal: bool = False) -> str: So, I would very much prefer to make LAAs the default. At most, you should randomly generate addresses within an OUI you own. In fact, I find it highly dubious to randomly generate UAAs at all. However, I disagree with making universally administered addresses the default. It is probably what users will usually need more often. I agree with the choice of making Unicast the default. I would make them keyword-only arguments so that the caller is always forced to name them: def random_eui48(*, unicast: bool = True, universal: bool = True) -> str: Having two boolean parameters can lead to confusion. So, your function should probably be named random_eui48 instead. For example, FireWire MAC addresses are EUI-64. It is also imprecise, since not all MAC addresses are EUI-48 addresses. These names should only be used as an obsolete label for EUI-48. The IEEE strongly discourages use of the name MAC or MAC-48. Speed isn't a huge concern, but I'm curious if there's a cleaner way that I'm missing.ĭef random_mac(unicast: bool = True, universal: bool = True) -> str: vidfilerandom (file) - uses random line from wiresharks manuf file vidfilevendor (file, vendor name, descoptional) - specify a vendor name, uses wiresharks manuf file instead of being completely random.

Attaching the first octet to the rest is suboptimal as well. totalrandom () - Procedurely generated MAC address, using random function.

Is treating a boolean value as a number during bitwise operation idiomatic? Is it clear as I have it now?.

The numbers kind of sit on a border of self-explanatory and magic, so I decided to name them to be safe.

The number constants are bugging me too.

I tried explicitly setting the bits, but the code to decide between |, and & and ~ got messier than what I have now, so I went with this way.

Is there a better approach? It feels hacky generating it as two pieces then adding them together.

It's not a lot of code, but I'd like a few things reviewed: It works, but it's ugly and looks suboptimal. The LSB of the first octet indicates uni/multicast, and the second LSB of the octet indicates universal/local, so these bits can't be random.Īfter playing around with a few failed ideas (generating all random bits, then 'fixing' the two bits later), I finally decided to generate a random number between 0 and 63 inclusive, left shift it twice, than add the two bits on after. This caused me headaches though because I'm still not great at dealing with bits.

I decided to allow the user to pick if it's unicast/multicast and universally/locally administered even though I'll only need unicast/universal. Python hacking script to change Windows 10 WiFi MAC address. > random_mac(unicast=True, universal=False) > random_mac(unicast=False, universal=True) I need the ability to generate random MAC addresses, so I wrote up a little function that does that: > random_mac()
