A zone is the combination of the top level domain (currently, these include: .com, .edu, .org, .net, .gov,.int, .mil, .arpa, and the country codes) and the secondary domain. Some examples of zones would be: slashdot.org, colorado.edu, and ibm.com.

Many refer to this as the "domain name," although this is incorrect. A domain name includes both the zone, and any additional specifying information (further subdomains or a hostname). For my above examples, cs.colorado.edu, ftp.slashdot.org, and www.ibm.com would all be "domain names."

According to the book "DNS and BIND",


A zone contains the domain names
that the domain within the same
domain name contains, except for
domain names in delegated subdomains.

Say what?

"Zone" is also the title of a poem written by Guillaume Apollinaire in 1912. "Zone" was published in his Alcools collection in 1913 as the first piece in the book, although it was the final one composed for the sequence (Bloch, 2017). The Alcools (tr. as Spirits) collection contains numerous other well-regarded verses, including "L'Adieu" and "Le Pont Mirabeau." Perhaps the publisher placed "Zone" as the lead-off piece in the collection to catch the eyes of bookstall browsers; or alternatively, Apollinaire may have chosen to give it that position during his manuscript preparation.


In References below I provide a link to a second, posthumous edition of Alcools, which is a digitalized photographic reproduction of the Gallimard 1920 publication, so that you can easily see the remarkable French poem "Zone" or peruse Alcools further if interested. Apollinaire died in the Spanish Flu pandemic of 1918, age 38.
