This will get more reading? Once it got to "trees" and "leaves" I had to
get the storm boots... :)
Can we make it any more complicated? Even though I do admire you that
grasp and work with
this stuff. One day, maybe.
Best,
Duncan

"The Domain Name System (DNS) distributes the
responsibility for assigning
domain names and mapping them to IP networks by
allowing an *authoritative
server(s) for each domain to keep track of its own
changes*, avoiding the need
for a central registrar to be continually consulted
and updated."
"The domain name space consists of a tree of domain
names. Each node or leaf in
the tree has one or more resource records, which hold
information associated
with the domain name. The tree sub-divides into zones.
*A zone consists of a
collection of connected nodes authoritatively served
by an authoritative DNS
nameserver.* (Note that a single nameserver can host
several zones.)"
