[Yum] PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'"

Hello,

The content of /etc/sysconfig/network is:
NETWORKING_IPV6=no
NETWORKING=yes
HOSTNAME=192.168.11.218

/etc/sysconfig/network-scripts/ifcfg-eth0 is:
EVICE=eth0
#BOOTPROTO="dhcp"
BOOTPROTO=none
NM_CONTROLLED=yes
ONBOOT=yes
TYPE=Ethernet
UUID="*****************************"
IPADDR=192.168.11.218
PREFIX=24
NETWORK=192.168.11.1
NETMASK=2555.255.255.0
DNS1=194.167.31.3
DEFROUTE=yes
###### next two lines added to test
IPV4_FAILURE_FATAL=yes

DNS2=194.167.30.130
GATEWAY=192.168.11.1
USERCTL=no
HWADDR=****************
LAST_CONNECT=1382626237

/var/lib/dhclient/dhclient-eth0.leases contains:

lease {
   interface "eth0";
   fixed-address 192.168.11.59;
   option subnet-mask 255.255.255.0;
   option dhcp-lease-time 86400;
   option routers 192.168.11.1;
   option dhcp-message-type 5;
   option dhcp-server-identifier 192.168.11.1;

}
lease {
   interface "eth0";
   fixed-address 192.168.11.59;
   option subnet-mask 255.255.255.0;
   option routers 192.168.11.1;

   renew 4 2013/10/24 20:43:42;
   rebind 5 2013/10/25 06:12:51;
   expire 5 2013/10/25 09:12:51;
}

This is strange, why is the fixed-adress does not end with 218? In  
addition, ifconfig returns:

eth0      Link encap:Ethernet  HWaddr ****************
           inet adr:192.168.11.218  Bcast:192.168.11.255

           RX bytes:1000 (1000.0 b)  TX bytes:1000 (1000.0 b)

To finish:
[root at 192 nico]# ip  -f inet6 addr show eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
     inet6 fe80::6e3b:e5ff:fe0d:95f9/64 scope link
        valid_lft forever preferred_lft forever

I do not know if there are expected values.

What should I do know?

Thank you

Nicolas
