Checksum does not include any IPv4 header fields. This seems like a
bad design choice. Note that in the IPv6 case, the checksum does
include a pseudo-header. Why not be consistent?

this doesn't seem good. The spread between these values can be pretty
wide, I think. What you want is an average value with some randomness

QUestion: is there a MIB doc (in development) for the management variables

Comment from OPSDIR (Pekka) review:

    Although MRD messages could be sent as ICMP messages, the group
    management protocols were chosen since this functionality is
    multicast specific.
