DynDns problem... with configuration or with system configuration?

I have a registered account with DynDns, and every month I am sent a reminder that my account will expire because it is not in use (i.e. inactive).

I think the problems stems from my system's inability to register itself on a periodic basis using ddclient. This is the error I am getting:
Mar  4 06:53:09 iceland ddclient[2352]: WARNING:  cannot connect to socket: IO::Socket::INET: Bad hostname ''
When I ping '', I do so successfully. I can also connect to its port 80 (using a port-scanner application I developed).

So why the error? I get the same error message every 5 minutes.

I have a Fedora 9 OS. Below is the relevant portion of my /etc/ddclient.conf file (with the username and password changed for security purposes):
## To obtain an IP address from Web status page (using the proxy if defined)
use=web,, web-skip='IP Address' # found after IP Address
#use=ip,                     ip=       # via static IP's
#use=if,                     if=eth0            # via interfaces
#use=web                                        # via web
#protocol=dyndns2                               # default protocol                 # default proxy                      # default server                 # default server (bypassing proxies)

login=myuserid                                  # default login
password=mypassword                             # default password                            # default MX
#backupmx=yes|no                                # host is primary MX?
#wildcard=yes|no                                # add wildcard CNAME?
Somehow I feel that the contents of /etc/hosts may be responsible for the error, but I'm not sure.
# Do not remove the following line, or various programs
# that require network functionality will fail.       localhost.localdomain localhost iceland.localdomain iceland
::1             localhost6.localdomain6 localhost
My system's name is 'iceland'.

Try to change in your ddclient.conf:




use=web, web=

It's the IP to the I think it should solve the problem.
