# Building the MAC address database
|
|
|
|
The MAC address database can be created using the `build-database.py` script.
|
|
|
|
There are 2 online services supported:
|
|
|
|
* [https://maclookup.app](https://maclookup.app) default
|
|
* [https://macaddress.io](https://macaddress.io) not free any more, but still supported
|
|
|
|
The script will download the latest registered MAC address block information
|
|
from [https://maclookup.app](https://maclookup.app) and creates a size and access optimized
|
|
SQLITE database file.
|
|
|
|
The generated database is read performance optimized and tried to keep as small as possible for
|
|
searching MAC address OUIs (Organizationally Unique Identifiers) blocks and returning the registered company name.
|
|
|
|
$ python3 build-database.py
|
|
|
|
The final database will be named `mac-addresses.db`.
|
|
|
|
In nymea the `MacAddressDatabase` class will provide access to this generated database and provides an asynch threaded mechanism to get the company name for a given MAC address.
|
|
|
|
The database will be searched in the system default data location `${XDG_DATA_DIRS}/nymead/`.
|
|
|
|
On debian package based system the database file will be installed in `/usr/share/nymea/nymead/mac-addresses.db`.
