Hello,

   Maybe this is not exactly what you are looking for but probably is 
closed enough.

   Summary: in LACNIC for two years in a row we have been working in 
identifying which CPEs are the most common in the part of the world, and 
then looking for which transition mechanisms are supported by them.

   We have published two documents about it. Both can be found in here:

https://www.lacnic.net/5832/1/lacnic/

   The direct link for the latest one is here:

https://www.lacnic.net/innovaportal/file/4297/1/informe-cpes-ipv6-2020-v7.docx.pdf


    I know they are in Spanish :-(  sorry for this.

   Hope this helps to you and probably more people.


Alejandro,
