Our database comes in the following forms: JSON, CSV, XML, Cisco vendorMacs.xml for maximumcompatibility and fast integration into existing systems. We have talked about mac addresses used in multicast world and the 32 same ip addresses that is used with the same mac addresses. Download an exhaustive MAC Address Vendor Databasefor your educational, business or enterprise needs. In this lesson, we have learned an important lesson of multicast technology. For another Multicast MAC, there are another 32 ip addresses certainly. This is tru for all these 32 ip addresses. These Multicast IP Addresses that can be used with this created MAC Address are given below:įor example like 224.255.0.1 multicast ip address, 230.127.0.1, 232.255.0.1, 238.255.0.1 ip addresses will also use the same MAC that we have produced. Here, with the 5th, 6th, 7th, 8th and 9th bits, 32 different Multicast IP Addresses can be written.
So, 2^5, you can create 32 different IP address with this changable area.įor our example, the Multicast IP addresses that share the same Multicast MAC Address are showed below.

The second part, host code identifies the device within the other devices of that vendor. The first part, vendor code is given by the device vendor. And these 48 bits are divided into two as vendor code and host code. 24:46:C8 Motorola Mobility LLC, a Lenovo Company - Motorola Mobility LLC, a Lenovo Company. As you know, a MAC address consist of 48 bits. And the remainning 5 bits in the middle can be any value. A4:45:19 Xiaomi Communications Co Ltd - Xiaomi Communications Co Ltd.
The last 23 bits are used for Multicast MAC Address. It is 25 bits.Ĥ) Lastly, we will combine the fixed 25 bits with the last 23 bits of the multicast ip to create our Multicat MAC Address :Ġ0000001:00000000:01011110:0 1111111.00000000.00000001 = 01:00:5e:7F:00:01įor Multicast IP Address, the first 4 bits are fixed, these first four bits are 1110. 3) We will take the fixed part of the Multicast MACs like below and we will write it in binary format.
