What Ted said (at most we can deprecate features, but not unify some features into a new feature. There is an xkcd for that...)... but also: the DUID generation is essentially a local client matter, so this multiplicity of formats does not really affect the protocol or require any extra code. Servers can and do treat all DUIDs as opaque blobs of bytes, and that's it. (Mine does this.) Some DUID formats can elucidate more info for the servers and operators that care, but as the trend on clients (dnsmasq, I think) is towards feeding some stuff into a hash function and saving the result for later on. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | network architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [ -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works -= IPv6 IoT consulting =-
