I'm using the following check command (in checkcommands.cfg):

 # 'check_dns' command definition
 define command{
         command_name    check_dns1
         command_line    $USER1$/check_dns -H www.<our-web-server.com
-s $HOSTADDRESS$ -a <our web server's IP address>

define command{
         command_name    check_dns2
         command_line    $USER1$/check_dns -H www.<our-web-server.com
-s $HOSTADDRESS$ -a <our web server's IP address>

Shouldn't that work to verify OUR DNS server is up and replying? Do I
need both of them or shouldn't just the one work?

Also, when looking at Service or Host Alert History I see a bunch of this:
