|
|
* The domain name space is a tree structure. Each node and leaf on the

|
|
* 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.
|
|
*
|

|

* 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.
