 Every complete hostname (e.g., nubark.atrust.com) is a node in the forward branch of the tree, and (in theory) every IP address is a node in the reverse branch.
 
-To allow the same DNS system to manage both names (which have the most significant information on the right), and IP addresses (on left), the IP branch of the namespace is inverted by listing the octets of the IP address backwards. For example if host `nubark.atrust.com` has IP `63.173.189.1`, the corresponding node of the forward branch is `nubark.atrust.com.` and the node of the reverse branch is `1.189.173.53.in-addr.arpa.`. Both of these names end with a dot, just as the full pathnames of files always start with slash. That makes the **Fully Qualified Domain Names** or FQDNs.

 Two types of TLDs exists: country code domains (ccTLDs) and generic domains (gTLDs).
