Problem with ACL in named.conf

[GS Bryan]

I tried to use the acl statement in my named.conf file, but I have a
hard time making it work. In my named.conf file, I've put these acl
statements in these formats (made up IP addresses mind you):-

----------
// Individual ACL list

acl addr1 {
	11.22.33.44;
	12.23.34.45;
};

acl addr2 {
	22.33.44.55;
	5.4.3.2;
	99.0.0.0;
};

acl addr3 {
	111.3.4.5;
	2001:3000::1;
	122.3.4.5;
	2001:3000::2;
};


// Nested ACLs list

acl alladdr {
	addr1;
	addr2;
	addr3;
};

------------

Then when I put the 'alladdr' thing in my 'allow-transfer' and
'also-notify' arguments, as shown below, BIND will fail to start:-

-----------

zone "example.net" {
        type master;
        file "examplenet.conf";
        allow-transfer { "alladdr"; };
        also-notify { "alladdr"; };
		key-directory "keys/examplenet/";
		inline-signing yes;
		auto-dnssec maintain;
};

-------

Here is the log:-

>From examples I read from the Internet, I don;t think I have done
anything wrong. If I put all the IP addresses from addr1, addr2 and
addr3 into the allow-transfer and also-notify statements, BIND will
start normally without problems.

Thanks for reading.
