Parser library for Wireshark's OUI database

Project description

Parser library for Wireshark's OUI database.

Converts MAC addresses into a manufacturer using Wireshark's OUI database.

Optimized for quick lookup performance by reading the entire file into memoryon initialization. Maps ranges of MAC addresses to manufacturers and comments(descriptions). Contains full support for netmasks and other strange things inthe database.

See Wireshark's OUI lookup tool.

With PyPi

Or Manually

Usage

As a library:

As a command line:

Use a manuf file in a custom location:

Automatically update the manuf file from Wireshark's git:

Note, that this command will update the manuf file bundled with this package. If you do not wish tomodify this, or do not have permissions to do so, you must specify a custom manuf file to perform an update.

Alternatively you can call the program with:

or by executung the manuf.py script directly

Features and advantages of manuf

Note: the examples use the manuf file provided in the first commit, 9a180b5.

manuf.py is more accurate than more naive scripts that parse the manuf file.Critically, it contains support for netmasks.

For a usual entry, such as BC:EE:7B (AsustekC), the manufacturer 'owns' thelast half (24 bits) of the MAC address and is free to assign the addressesBC:EE:7B:00:00:00 through BC:EE:7B:FF:FF:FF, inclusive, to its devices.

However, entries like the following also appear commonly in the file:

/36 is a netmask, which means that the listed manufacturer 'owns' only the last12 bits of the MAC address instead of the usual 24 bits (since MAC addressesare 48 bits long, and 48 bits - 36 bits = 12 bits).

This means that Converging Systems is only free to assign the addresss block00:1B:C5:00:00:00 through 00:1B:C5:00:0F:FF. Anything after that belongs toother manufacturers. manuf.py takes this fact into account:

Even Wireshark's web lookup tool fails here. '00:1B:C5:00:0F:FF' returns only'IEEE REGISTRATION AUTHORITY' while it should instead return 'ConvergingSystems Inc.' If a netmask is not explicitly specified, a netmask of /24 isimplied. Since this covers most of the entries, most tools only parse the first24 bits.

manuf.py fully supports even more esoteric entries in the database. For example,consider these two entries:

With a netmask of /45, only the last 3 bits of the address are significant.This means that a device is considered 'OAM-Multicast-DA-Class-1' only if thelast digit falls between 0x0 and 0x7 and 'OAM-Multicast-DA-Class-2' only if thelast digit falls between 0x8 and 0xF.

If the last octet is 0x40 or over, or 0x2F or under, the address doesn't belongto any manufacturer.

Again, the official lookup tool fails here as well, with '01:80:C2:00:00:31'returning no results.

Algorithm

Although optimized for correctness, manuf.py is also quite fast, with averageO(1) lookup time, O(n) setup time, and O(n) memory footprint.

First, the entire manuf file is read into memory. Each manuf line is stored ina dict mapping a tuple calculated from the MAC address and netmask to eachmanuf:

The (48 - netmask) value is called the 'bits left' value in the code.

For example, Converging Systems' MAC is 0x001BC5000000 and its netmask is 36,so its key in the dict is this:

To lookup '00:1B:C5:00:0F:FF' we will check the dict beginning with a 'bitsleft' value of 0, incrementing until we find a match or go over 47 (which meanswe have no match):

Since (12, 0x001BC5000FFF >> 12) equals (12, 0x001BC5000000 >> 12), we have amatch on the 13th iteration of the loop.

Copying

This library does not link to Wireshark's manuf database; it merely parses it,so I have chosen to publish it under the LGPLv3 and Apache License 2.0instead of the GPLv2. The manuf database is provided for your convenience inthis repository, but will not be updated.

• License for Python library: LGPLv3 and Apache License 2.0 (dual licensed)
• License for manuf database: GPLv2

The latest version of the manuf database can be found in theWireshark git repository.The database there is updated about once a week, so you may want to grab thelatest version to use instead of using the one provided here by using the--update flag on the command line:

OUI Lookup Tool

The Wireshark OUI lookup tool provides an easy way to look up OUIs and other MAC address prefixes. It uses the Wireshark manufacturer database, which is a list of OUIs and MAC addresses compiled from a number of sources.

Directions:
Type or paste in a list of OUIs, MAC addresses, or descriptions below. OUIs and MAC addresses may be colon-, hyphen-, or period-separated.

Examples:
0000.0c
08:00:20
01-00-0C-CC-CC-CC
00d9.d110.21f9
01-23-45-67-89-AB-CD-EF
