Recieving diffrent NAS Identifiers in the Accounting requests

Hi, I was wondering what the radius server response would be to accounting-start and accounting-stop packets which arrive with different nas-identifiers (or nas-ip-address). This situation has not been dealt with in the RFC. So is the implementation specific? Could some one please give some information on this?
