Machine is an internal server with zero need to provide or receive ip addresses using dhcp (all IPs are hard coded). Question: how do I disable dhcpv6-client on this box?

So, I'm seeing a bunch of DHCPv6 traffic coming from my CentOS7 machines. Basically, the machines are trying to send router solicitations, the packets are blocked at their egress firewalls, and I get to see the logs. I don't wish to disable IPv6. I don't wish to statically configure IPv6 at this time. I wish to have the m...

Is there an DHCPv6 client in CentOS that supports prefix delegation correctly? The old version of dhclient can't set a requested prefix delegation length, so isn't very useful, and I can't get the even-older wide-dhcpv6 from EPEL to work. -- Chris Adams <linux at cmadams.net>

DHCPv6 is really unusual. IPv6 addressing and routing is set up almost entirely in the kernel, unless you're using static addresses. IPv6 is neither harder nor easier with NetworkManager, in my experience.

Hello; I've run into a rather interesting problem on CentOS 7. According to sysconfig.txt (part of the initscripts documentation), I can set the following variables in ifcfg-ethX: DHCPV6C="yes" DHCPV6C_OPTIONS="-S" I've done so, but nothing is populated to /etc/resolv.conf and so DNS does not work. Interestingly, if I remove the latter option, an IPv6 address is added to the relevant interface. Packet dumps indicate that the required DNS information is be...
