about allow-update

[Tech W.]

Dear list,

Currently I'm using TSIG key for dynamic update auth.

allow-update {key "mykey";};

Besides TSIG key, I want to limit the source address also.
That's to say, I want the given address with specified key to execute the update only.

How can I do it? Is this syntax correct?

allow-update {key "mykey"; 192.168.1.254;};


Thanks in advance.
