After running yum update on Centos 6.6 i am getting network issues with DNS/IPV6

Hi

I run yum update on Centos 6.6 and it just update some system files and install a new kernel but i didn't reboot and after that i have many issues with my network dns/ipv6

Even yum update is not working:

[root@server ~]# yum update

Loaded plugins: downloadonly, fastestmirror, priorities

Setting up Update Process

Determining fastest mirrors

Could not retrieve mirrorlist [url removed, login to view] error was

14: PYCURL ERROR 6 - "Couldn't resolve host '[url removed, login to view]'"

Error: Cannot find a valid baseurl for repo: base

Even if i add this on my hosts that i can ping the ip:

[url removed, login to view] [url removed, login to view]

Also if i use wget and a link to file is not working but if i use wget -4 and the same file link is working!!!

Also checking some system settings i found some new entries related to ipv6 that i remove:

hosts file:

::1 localhost [url removed, login to view] localhost6 [url removed, login to view]

and on nameservers i got a line:

search [url removed, login to view]

Some other info also:

/etc/hosts:

127.0.0.1 localhost [url removed, login to view]

[url removed, login to view] [url removed, login to view] server

/etc/sysconfig/network:

NETWORKING=yes

HOSTNAME=[url removed, login to view]

GATEWAY=[url removed, login to view]

/etc/[url removed, login to view]

# Generated by NetworkManager

nameserver 8.8.8.8

And then reboot the server but nothing

also i have this:

/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"

BOOTPROTO="static"

DNS1="8.8.8.8"

GATEWAY="[url removed, login to view]"

HWADDR="0C:C4:7A:02:CA:xx"

IPADDR="[url removed, login to view]"

NETMASK="255.255.255.0"

NM_CONTROLLED="no"

ONBOOT="yes"

TYPE="Ethernet"

UUID="cb7ea12f-2ab7-45a1-896f-8ff948d7xxxx"

and this:

/etc/[url removed, login to view]

passwd: files

shadow: files

group: files

#hosts: db files nisplus nis dns

hosts: files dns

bootparams: nisplus [NOTFOUND=return] files

ethers: files
