So on Unix/linux systems only the ip address is relevant.
Is that true both for OpenAFS client and servers?
On Windows clients there must be consistency between the ip address and
the DNS entry of the #hostname portion of CellServDB file

In the documentation for the CellServDB file (both client & server)

it is declared that is the "fully qualified hostname"
that must be provided in the line defining a dbserver.
So even if a dbserver has an alias in the DNS different from the hostname, it
is definitely the hostname that must be provided in the CellServDB line.
Have I well understood?
So reading the CellServDB file OpenAFS considers that at a given IP address it
will find the hostname defined in the CellServDB file line.
(by the way: we do not have AFSDB records in our DNS)
The "#hostname" portion of a CellServDB server line is only processed
by OpenAFS when running on Windows. It is ignored on other platforms.
I only know that whatever is there has to be resolvable by Windows
gethostbyname(). I don't know if it has to be fully-qualified, but
I suspect that depends on the configuration of your Windows resolver.
If it cannot be resolved for any reason, the Windows code falls back
to the IP address specified in the first token.
