I need to configure on a network interface (eth1) with static IPv6 and get an IPv4 address from DHCP on a CentOS 6 machine?

Using the configuration below I only get a dynamic IPv4 address:


But there is no global IPv6 address assigned.

Does your system actually support IPv6? – Michael Hampton Dec 25 '13 at 17:07
Yes it supports IPv6 I've been able to set static IPv6 Only. – Chedy2149 Dec 26 '13 at 9:11
I guess static address is ignored since BOOTPROTO=DHCP. Why do not you make reservation for IPv6 on the same DHCP server? – Veniamin Dec 27 '13 at 15:44
The same DHCP server does not provide ipv6 addresses only IPv4 addresses. – Chedy2149 Dec 28 '13 at 5:17
Then try to make alias eth:0 and custom IP setup for It. – Veniamin Dec 28 '13 at 7:03
