The input string can also be a blessed NetAddr::MAC object. We only need the first three bytes 00:0d:93:29:f6:c2 # usual form They can omit leading 0's (which might make things look odd). The input string can be a separated by colons or hyphens. Takes a MAC address and turns it into the form I need to send to the IEEE lookup, which is the first six bytes in hex separated by hyphens. The normalize_mac() function explains the possible formats for MAC. This makes a direct request to the IEEE website for that OUI to return the information for that vendor. Different records may have different numbers of lines, although the first two should be consistent. The first element is the vendor name, and the remaining elements are the address lines. Given the MAC address, return an anonymous array with the vendor information. Return the Mojo::UserAgent object used to fetch resources. If the cache is fully loaded (perhaps using load_cache), it may not even use the network at all. This method does try to use a cache of OUI to cut down on the times it has to access the network. I can pass it a list of MAC addresses and run() processes each one of them.

It takes the MAC addresses and prints the registered vendor information for each address. If I call this module as a script, this class method automatically runs. The module can read and decompress compressed versions (as long as the url reflects the compression type in the filename as the linuxnet.ca links do). These files are large (about 4MB), so you might want to cache a copy.Ī different source of information is linuxnet.ca that publishes sanitized and compressed versions of the list, such as: There are older copies of the OUI file in the GitHub repository. Here are some of the old URLs, which also flip-flop schemes: If they do that again, you can set the NET_MAC_VENDOR_OUI_URL environment variable to get the new URL without updating the code. The IEEE moves the location of its OUI file. You can use this as a module as its individual functions, or call it as a script with a list of MAC addresses as arguments. With vendor information, you can often guess at what what you are looking at ( e.g. You can, for instance, scan a network, collect MAC addresses, and turn those addresses into vendors. This module allows you to take a MAC address and turn it into the OUI and vendor information. Each interface has a Media Access Control (MAC) address of six bytes.

The Institute of Electrical and Electronics Engineers (IEEE) assigns an Organizational Unique Identifier (OUI) to manufacturers of network interfaces. The module realizes it is a script, looks up the information for each MAC, and outputs it. You can also run this as a script with as many arguments as you like. My $array = Net::MAC::Vendor::lookup( $mac ) Version 1.268 SYNOPSIS use Net::MAC::Vendor If you chose “Dell Inc.”, you will be presented with a complete page detailing the company information, address as well as the MAC addresses owned by this vendor.Net::MAC::Vendor - Look up the vendor for a MAC VERSION Type “De” in the search box, and the API will list all the vendors starting with this prefix. Let’s say that you are looking for all MAC address vendors starting with “De”. You are provided with complete information about the MAC address vendor you looked for. Using OUILookup, you don’t simply have the details of the MAC address you are looking for. Make sure to come back every week in order to check the latest guides they wrote for you. They careful explain how you can find your MAC address on various operating systems or using different tools such as Wireshark.

One of the strengths of OUILookup is probably its well documented blog.Įvery week, experienced writers provide you with the best tutorials and resources on MAC addresses and vendors. In this case, the API answered with 3 known vendors : Kansai Electric Ltd, Cascade Communications and Analog Devices Inc.
