Teemu, MTU is already mentioned there.
I mentioned DNS, becasue i consider Prefix and DNS the duo responsible for basic internet connectivity, while MTU is something extra for even better connectivity.

If not explicitly defined, maybe the following statement needs to leave some space for other data that are passed to the LAN link through the RAs.
