Function Addon: GetMulticastMAC()

[ffranz <ffranz@…>]

GetMulticastMAC()

This function provides a MAC address from the multicast MAC created by IANA. With a total of 66 111 possible MACs, the MAC can be random if the parameter is omitted or is zero. Also, you can obtain a MAC by index within the range 1-66111.For use in fuzzing probes.Develop in scapy-2.1.0.

Attached patch. More info: www.iniqua.com/labs

Examples: ...

/>>> print GetMulticastMAC(0)

ab:00:04:01:5e:43

/>>> help(GetMulticastMAC)

...

/>>> for i in range(66111): print GetMulticastMAC(i)

...

Cheers. ffranz.
