Re: [v6ops] Thoughts about wider operational input

["E. Marie Brierley" <[e-mail]>]

Great point. If you can quantify that issue by some means, I can add it to my comms to digital marketers (along with geolocation deterioration). Cart conversion is extremely low <3%, so any factor that can be incrementally quantified and improved is welcome in that audience.

That suggests to me that an even earlier question is:

  - What business problems does IPv4 cause today?

For example, I'm convinced that multiple layers of NAT44 (today's reality) cause problems, whose symptoms are often (from the end user's view) failed sessions that have to be repeated. These are *never* reported to any help desk and so don't appear in anybody's statistics - but they do detract from user experience and so presumably have an impact: lost or delayed
business.

Others have mentioned the OPEX cost of diagnosing NAT-induced problems even with the enterprise.

What else?

The difference is that "today" most SMEs don't have that problem because they don't have PI, but it may turn the same when they realize that not being PI have renumbering issues if changing the ISP. Of course, again, if we talk about a "small" SME, then may not be an issue, they only have 40 or 50 devices to renumber (your mileage will vary), not easy but not "terrible".
