"Requesting node"? > After merging RFC3633 into the RFC3315, many of the sections (in particular those talking about the messages transmission and reception) include common text for processing IA_NAs and IA_PDs and they use the term "Client" (as it used to be in original RFC3315) for an entity that can request addresses and prefixes. Hence, I'd suggest we continue using the term "Client" where possible, which probably also means replacing some of 72 occurrences of "delegating router". Perhaps we should also update section "5.3. DHCP for Prefix Delegation" to say that prefix delegation is a mechanism that can be used to provide prefixes to routers but also hosts. Marcin
