> Actually the answer here is also "yes, negatively". It means that networks with large numbers of users would become unreliable because of IID collisions. There are networks that run 10k or 20k nodes on a single subnet. Large corporate networks are an example, or large conferences such as MWC.

I would love a way to instrument that.  We can do the probability math, but I’d be curious to see real stats for “On a network of X nodes, the average DAD failure rate was Y.”  I had a segment once with about 6k clients, but I didn’t consider figuring a way to instrument DAD collisions.
