I'm not sure why one would presume to start there. As I read the following
fragment
of RFC 1034, the list of labels explicitly starts at the node of interest and
is read
towards the root.
The domain name of a node is the list of the labels on the path from the
node to the root of the tree. By convention, the labels that compose a
domain name are printed or read left to right, from the most specific
(lowest, farthest from the root) to the least specific (highest, closest
to the root).
