Setting up IPv6 support on CentOS safely?


/etc/sysconfig/network

contains:
Quote:
NETWORKING_IPV6=yes
/etc/sysconfig/network-scripts/ifcfg-em1
my main Ethernet interface contains:
Quote:
DEVICE="em1"
BOOTPROTO="static"
DNS1="127.0.0.1"
GATEWAY="***"
HWADDR="***"
IPADDR="***"
IPV6INIT="yes"
IPV6ADDR="2604:***:***:***:0000:0000:0000:0002"
IPV6_DEFAULTGW="2604:***:***:***:0000:0000:0000:0001"
NETMASK="255.255.255.248"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="***"
:0000:0000:0000:0002 or ::2 ?

What else needs to be done to enable IPv6 in the Linux CentOS 6.x 64bit?

To apply configuration, is it safe to do "service network reload" while im accessing server from different country via SSH ? Thank You

What else HAVE you done, and have you actually TESTED this?

"Safe" how??? If you have an additional IPv4 address, it won't matter if V6 comes up or not...you can still access it. And if this is a hosted server, you pay for support, so USE IT, and call them to help resolve whatever issue(s) you have?

There are over 83,000 hits in Google for "how to configure ipv6 on centos6"; what research have you done/read/tried???
