I think you should trust Wikipedia over the RFC.   Wikipedia is always right.


Seriously, I don't know why RFC3315 specifies a length limit.   128 seems like a sensible number, though, if there needs to be a limit.   I'm sure the limit made sense at the time, and given that it's in the spec, you have to honor it or risk interoperability problems, regardless of what the ISC server does with over-long DUIDs.
