One nameserver not responding

[hendrik250874]

Hello,
I'm stuck. Something is wrong and it seems I'm unable to find it.
I got from http://www.intodns.com/<somedomainihave.com> the following: DNS servers responded ERROR: One or more of your nameservers did not respond:
The ones that did not respond are: 87.237.14.17.

I found this: http://help.directadmin.com/item.php?id=387, so I did this:
#netstat -lnp | grep named

tcp 0 0 87.237.14.16:53 0.0.0.0:* LISTEN 2089/named
tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 2089/named
udp 0 0 87.237.14.16:53 0.0.0.0:* 2089/named
udp 0 0 127.0.0.1:53 0.0.0.0:* 2089/named

Seems to be missing the second IP.
The other items from the help.directadmin.com/item.php?id=387 are ok.
When I look in named.conf, there is no IP listed, so I'm not sure where to add it.
Can anyone help ?

I've added
listen-on { any; }; and it seems all is going well.
Thank you for the support.
