Well, RDATA is kind of a fundamental part of DNS. It's the "payload" of
any given Resource Record. For instance, the RDATA of an A (address)
record is the address itself, the RDATA of an MX (Mail eXchanger) record
is a combination of the name of a mail server and the relative
preference which it should be given among all of the mail servers for
the domain name. Different record types have different RDATA structures,
so it's not that easy to generalize.
Looks like you flubbed the syntax for your nsupdate prereq or update
commands, e.g. an improperly formatted address for an A-record update, a
missing preference value for an MX-record update, the wrong number of
fields for an SOA record, or non-numeric where only numeric was
expected. Something like that.
