A media access control (MAC) address is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi.
MAC address structure
A MAC address is comprised of six octets or in other words, six 8 bit long segments. The first three octets make up the Organisationally Unique Identifier (OUI), i.e., it can be used to identify the device's manufacturer. Refer to the figure below for a visual representation:
Starting with week 9 of 2023, most manufactured Teltonika Networks devices will have a new MAC address ranging from 20:97:27:00:00:00 to 20:97:27:FF:FF:FF.
Note: that certain devices will have a primary MAC address ranging from 00:1E:42:00:00:00 to 00:1E:42:FF:FF:FF.
The following MAC addresses belong to Teltonika:
|Vendor||MAC prefix (OUI)||Possible MAC addresses|
|TELTONIKA NETWORKS UAB||20:97:27||20:97:27: [00:00:00 - FF:FF:FF]|
|Teltonika||00:1E:42||00:1E:42: [00:00:00 - FF:FF:FF]|
