Hello everyone, We just uploaded the next version for this draft. In addition to designating 6LBR for IID assignment, it also proposes a simple XOR'ed operation to deliver to 6LN the suggested IID in a space-efficient manner.
Currently, 128 bits are allocated in DAC/DAR to carry 'Registered Address' but this draft completely elides these 128 bits and exchange the address by aggregating it with EUI-64. Let us know your comments/views/suggestions. Thanks. Rashid Sangi.

Title : Designating 6LBR for IID Assignment Authors : Abdur Rashid Sangi Mach (Guoyi)Chen Charles E. Perkins Filename : draft-rashid-6lo-iid-assignment-01.txt Pages : 11 Date : 2016-06-16 Abstract: In IPv6 Stateless Address Autoconfiguration (SLAAC), randomizing the interface identifier (IID) is a common practice to promote privacy. If there are a very large number of nodes, as has been discussed in several use cases, the effect will to proportionately increase the number of IIDs. A duplicate address detection (DAD) cycle is needed for each configured IID, introducing more and more overhead into the network. Each failed DAD requires the initiating node to regenerate a new IID and undergo the DAD cycle again. This document proposes an optimized approach that requires 6LBR (6LoWPAN Border Router) to provide a unique IID, avoiding the potential duplication. Additionally, further optimizations are suggested to enable multiple concurrent DAD cycles and to return the suggested IID from 6LBR to 6LN in a space-efficient manner.
