Centos6.x completely disables ipv6

Ipv6 is not popular now, and it is almost useless. it should be completely disabled; otherwise, it will affect the actual application. For example, if you do not disable ipv6, you may use ipv6 to enable Google or even the ipv6 version, which is very slow and seriously affects your use. Specific Method: 1. modify/etc/sysconfig/network, append: NETWORKING_IPV6 = no2. modify/etc/hosts, resolve the local host name of ipv6

Ipv6 is not popular now, and it is almost useless. it should be completely disabled; otherwise, it will affect the actual application. For example, if you do not disable ipv6, you may use ipv6 to enable Google or even the ipv6 version, which is very slow and seriously affects your use.

Specific method:

1. modify/etc/sysconfig/network and append:

NETWORKING_IPV6 = no

2. modify/etc/hosts and comment out the local host name resolution in ipv6:

#: 1 localhost localhost6 localhost6.localdomain6

3. add at the end of/etc/modprobe. d/dist. conf

Alias net-pf-10 off
Alias ipv6 off

Then restart the system.

Run lsmod | grep-I ipv6 and ifconfig | grep-I inet6. if nothing exists, it indicates that it is disabled successfully.
