Their biggest difficulties generally lies in understanding the IPv6 addresses. The types of addresses, where to use each of them, the new format, etc. From a didactic point of view, it would be a bad idea to use ULAs and tell them: please don't forget to pretend that this ULA block is our Global Unicast block, and this other ULA prefix will be the "real" ULA in our lab. Something looking more like GUAs would be better. The prefix 2001:db8::/32 do represent GUAs in documentation. It is difficult to convince people that private addresses and NATs are not to be used in all situations. Using ULAs in the labs, instead of Globals, would not help. I fear that using ULAs would result in people used to see them in the wrong places, and could lead us to a situation where some networks would finish having just ULA addresses (and NAT66) in scenarios where it would not be the better choice. I would prefer to choose an arbitrary prefix, inside or outside 2000::/3, but that "looks like" a GUA, than use ULAs in the classes.
