+	    Get a multicast MAC from the list generated by IANA (http://www.iana.org/assignments/ethernet-numbers)
+		''' An Ethernet multicast address consists of the multicast bit, the
+		23-bit vendor component, and the 24-bit group identifier assigned by
+		the vendor.  For example, DEC is assigned the vendor component
+		08-00-2B, so multicast addresses assigned by DEC have the first
+		24-bits 09-00-2B (since the multicast bit is the low-order bit of the
+		first byte, which is "the first bit on the wire").'''
+		
+
+	    Index can be zero or another number.
+		- If valor is zero script will generate a random number (default Index = 0).
+		- Use index to generate a secuecial list. 
+	    Example:
+		...
+		>>> for i in range(66111): print GetMulticastMAC(i)
+		...
+		>>> GetMulticastMAC()
