ohai detects wrong ipv6 address about ohai

[rarenerd]

I can reproduce this on CentOS and RHEL 5.10 with Chef 11.16.2 / Ohai 7.4.0. These are the entries I see with IPv6 enabled:

  "ipaddress": "10.0.2.15",
  "ip6address": "fe80::a00:27ff:fee4:da36",

After setting "NETWORKING_IPV6=no" in /etc/sysconfig/network and adding "options ipv6 disable=1" the entries look like this:

  "ipaddress": "10.0.2.15",
  "ip6address": "10.0.2.15",

Having the same problem on CentOS 6.6/Chef 12.1.1/Ohai 8.1.1, in this case I can't use the snmp cookbook because it insists on configuring an ip6 source. Any suggestions?

Tested in a Virtualbox with the opscode-centos-6.6 image:

[root@localhost ~]# ohai --version
Ohai: 8.2.0
[root@localhost ~]# cat /etc/redhat-release
