@gnmeyer I'm a bit confused here.
Do we need all those new rendered files, just for the IPv6 example?
Isn't just this file enough?

The rendered files were made from the make generate-examples command as a target from the Makefile.
Looking at the other examples, they also have the rendered out files. Unless one of the workflows runs the make generate-examples command, all of these files should be fine to be merged in.
