Hey guys,



I have a question in regards to multicasting, this question is actually in the Exam Certification Guide for the BSCI Cahtper 17, Question #7.



7. Which of the following multicast addresses does not share a multicast MAC Address.


A. 225.145.1.1
B. 227.17.1.1
C. 235.17.1.1
D. 237.117.1.1


The answer shows as D. But, I get different multicast macs for A and D.


Here is what I get:


225.145.1.1

01-00-5e-91-01-01



227.17.1.1

01-00-5e-11-01-01



237.17.1.1

01-00-5e-11-01-1




237.117.1.1

01-00-5e-75-01-01



Am I doing something wrong, why do they say the only right answer is D?
