Why? it feels so strange.
I think the ifconfig output is wrong.
vim / etc/sysconfig/network-scripts/ifcfg-eth0

PROXY_METHOD= "none"
BROWSER_ONLY= "no"
BOOTPROTO= "static"
DEFROUTE= "yes"
IPV4_FAILURE_FATAL= "no"

IPV6_AUTOCONF= "yes"
IPV6_DEFROUTE= "yes"

there is nothing wrong with it.
/ etc/resolv.conf file is locked,

grep hosts / etc/nsswitch.conf

hosts: files dns myhostname

Thank you all
