DNS Names
DNS names have a hierarchical organization, consisting of domains nested within one another.
Names are written from bottom-to-top, with dots separating the levels. The root of the tree is
maintained by the Network Information Center (NIC). To join the Internet, you must contact
the NIC to get the authority to be a member. NIC will grant that access and the root name
server will be updated with this information. There is usually a name server at each node in
the DNS structure tree. A name is defined by listing each label separated by dots all the way
to the root label. For example: SULU.RALENG.VISARA.COM
The name can be fully-qualified which includes the dot after the top level domain or the name
can be relative to a known origin, in which case only part of the full name may be used to
identify the host. In the previous example, the name SULU can be used as a relative name to
identify the fully-qualified name, if the default domain is equal to RALENG.VISARA.COM.
The name is not case-sensitive. Labels must be 63 characters or less and domain names must
be less than or equal to 255 bytes. However, LINCS limits the length of a DNS name in a
query to 128 bytes. The label must start with a letter, end with a letter or digit, and have as
interior characters only letters, digits, and/or hyphens.
