![]() ![]() ![]() We have talked about mac addresses used in multicast world and the 32 same ip addresses that is used with the same mac addresses. 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. wido / mac2eui64.py Created 5 years ago Star 3 Fork 0 Code Revisions 1 Stars 3 Python 3 48-bit MAC to EUI-64 IPv6 Raw mac2eui64. 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. GitHub Instantly share code, notes, and snippets.And the remainning 5 bits in the middle can be any value. 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. > mac EUI('00-1B-77-49-54-FD') Accessing the EUI object in the string context. 3) We will take the fixed part of the Multicast MACs like below and we will write it in binary format. Standard repr() access returns a Python statement that can reconstruct the MAC address object from scratch if executed in the Python interpreter. ![]()
