Because of the arbitrary starting point of any domain name this term does not specify or mandate any starting point only that it must end with the root.
There is no commonly used term that describes a host-to-root domain name. At its face value it could equally well be a subdomain name. Defines a part of a domain name to the root. Defines that part of the Domain Name below the TLD in the domain hierarchy, for instance, in example. Term much less useful with ccTLDs since the registered domain name may in fact be the Third Level domain Name, for instance, example.
A sub-domain name will fully include the Domain Name. Technically, the name of a subdomain is also a Domain Name. Frequently used to mean what this book calls a 'domain name'. Zone Name Any part of a domain that is configured in a DNS server and which fully contains the Domain Name for which the owner is authoritative, for instance, example. A zone is an operational convenience for DNS software and not part of the domain naming hierarchy.
RFC describes sub-domains zones as subzones rather than re-use the term zone and to the process of creating sub-domains as 'cuts' in the name space. The term subzone appears to have been lost in history. A clause groups together related statements. What we call a clause is variously called a section, a clause, a statement or an option in other documents.
Webster defines a clause to be "a separate section of a discourse or writing; specifically : a distinct article in a formal document" which is good enough for us. What we call a statement is variously called a clause, a statement, an option, a substatement and a phrase in other documents.
Webster defines a statement to be "a single declaration or remark" which is good enough for us. Conventions Convention Explanation and Usage The dots appear in fragments of zone and other files and indicate that additional lines may or may not be present but have been omitted for brevity.
The dots should not be present in the real file. Used to indicate a comment in, say, a sequence of command lines. Lines beginning with this symbol should not be typed or present.
In the case of comments in a file we will always use the appropriate comment convention if one exists. Also Known As. Used to indicate that a particular term has alternate forms which may be widely used or have been used in the literature.

It is clear that in spite of the so-called paper-less world of computing many people still need or prefer I count myself among them a paper version of information. Web based material is great for checking specific topics or doing highly specialised tasks and hyper-links add significant power to tutorial material but when it comes to understanding something paper still seems to be the natural medium.
So the idea for the book was born with the lofty goals of bringing together in a single document - a book - all the required information for both immediate tactical use and by adding IPv6 and DNSSEC provide something that would last some time into the future.
And to try and cover the material in a way that is as comprehensive as possible not just cherry-pick the normal stuff. So you will find every named. I will freely admit that as a consequence of the research for this book I discovered new RR types that I now regularly use but which I either never knew about or in other cases was vaguely aware of but would not spend the couple of hours necessary to verify the operational details since the actual applicability was not guaranteed.
Whether the book achieves its goals is for you the reader to determine.
