host commmand, bind v9.3.1

[Janardhan Molumuri]

Hi,

In bind v9.3.1, due to the recent addition of returning A,AAAA,MX
records bydefault for queries causing duplicate output when resolving
a cname.

Example:

> host www.google.com
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 66.249.89.99
www.l.google.com has address 66.249.89.104
www.google.com is an alias for www.l.google.com.
www.google.com is an alias for www.l.google.com.
>

In the above output "is an alias" line is repeated three times. From
debug mode the duplicate output is because of querying all A,AAAA,MX
records.

Any ideas?

Thanks,
-JNR.
