Hi list,

I did only read original Arifumi's document.

I also feel DA,DB and S description is a little bit confusing.
My understanding is here;

             DA(s,d)         DB(s',d')

              |              |
 subnet P(S,D) -------------------------

 prefix P is same for DA,DB and it can be described as s == s'. Is this
true? If yes, how about write their network factor into small letter?

But as for DNS round robin, current major OSs follows RFC3484 Rule9 and
neglect DNS information. RFC3483 rule9 is first and if someone wants to
utilize DNS round robin, 3484 policy table(disable subnet
prioritization) can be changed is the better indication I suppose.

Don't you put some note above that?
