Disabling IPv6 for specific connection
Q: Does this feature include the use case when I need to have ipv6 disabled for a specific connection, which includes not having any inet6 addresses in the interface (as seen by ifconfig), which I have even when using current (fedora 11) nm (unless removing the ipv6 module from kernel or disabling ipv6 other way)? -- user:Mso
Q: I'll extend the question. Right now there's a variable, IPV6INIT, which, according to ifup-ipv6 and ifdown-ipv6, is supposed to turn off IPv6 on an interface-by-interface basis. The only thing it really does is disable running ifup-ipv6. An interface still has at least a link-local address. Furthermore, if you manually flush all IPv6 addresses (ip -6 addr flush), unplugging the cable and plugging it back in brings back the link-local address. I know that's a function of how the kernel handles the interface, but will NM make up for it? --Akistler 05:06, 4 June 2009 (UTC)
Please don't require dhcpv6
I use radvd on my networks instead of dhcpv6. Don't hardcode NM to require dhcpv6.
- The NM package will require the dhcpv6 package, but whether or not it actually gets used will be configurable at runtime, as with IPv4 DHCP. You'll be able to configure IPv6 interfaces to use various combinations of static IP/routes, router advertisements, and DHCPv6. (Out of curiosity, how are you currently getting DNS information? Static DNS server addresses? DHCPv4?)
