# Okay, going to illustrate my thinking here:
|
|
# A ##Context## is a set of servers that operate together as
|
|
# authoritative for a group of zones.
|
|
|
|
# (I was going to call it a Network, but then I found out
|
|
# about https://doc.powerdns.com/authoritative/views.html )
|
|
|
|
# All ##Servers## within a Context are presumed to be
|
|
# using the same database and be otherwise interchangeable,
|
|
# Although given the limitations of some backends they can
|
|
# be set to read-only.
