* 3.1. Name space specifications and terminology
*
* The domain name space is a tree structure. Each node and leaf on the
* tree corresponds to a resource set (which may be empty). The domain
* system makes no distinctions between the uses of the interior nodes and
* leaves, and this memo uses the term "node" to refer to both.
*
* Each node has a label, which is zero to 63 octets in length. Brother
* nodes may not have the same label, although the same label can be used
* for nodes which are not brothers. One label is reserved, and that is
* the null (i.e., zero length) label used for the root.
*
* This has proven not to be a problem in the past as connections with FQDN's
* of greater than 63 characters are rejected by the server, and most FQDN's
* are shorter. It is possible to have a valid FQDN longer than 63 characters.
