First question, why use 2 keys? The combination of a key and an address
match list should be enough. Second question, what version of BIND are
you using? It probably doesn't matter, but it's good form to include
that information.

Doesn't look that way. The ARM is your best source for config info.

The include directive is related to adding an external file to your
named.conf. Unless that's what you're intending to do, you probably
don't want it here.

The term "keys" here would seem to indicate that you can add multiple
keys per server, but ...

> "key"; }; allow-update { key "key"; }; };

I don't see anything in the ARM about including key directives in the
allow-update or allow-transfer grammar.

You can probably also get some useful information by using named-checkconf.
