[users@httpd] find IP and PORT in use by Apache

[Mahmood N]

Hi,How can I find which IP:PORT Apache web server is monitoring? There are some 
network commands (netstat -pat), but they show the TCP port in use. The machine 
has multiple network interfaces and the Listen section in httpd.conf is 
commented. So, one of the is used by default and I don't know which one is set 
as default.
Any idea to find that? The linux is Cenos-6.1 running rocks.
  Regards,
Mahmood
