Is there some command I can use to determine if ipv= 6 > service is at my front door? There are two IPv6 equivalents to DHCP -- that's DHCPv6 and SLAAC. DHCPv6 needs some client software installed from ports IIRC. Apart from supplying IPv6 addresses it's pretty much the same as DHCP. However, perhaps the more 'native' autoconfiguration mechanism for IPv6 is SLAAC. To enable your machine to do SLAAC add: ipv6_activate_all_interfaces=3D"YES" rtsold_enable=3D"YES" That will get all your interfaces configured with IPv6 addresses -- at least a link local address, and where there is a router that can supply it, a unicast address and a default route. SLAAC can supply a few extra config bits, like dns server addresses but generally it is only used to configure IP numbers and routing. If your server is acting as a router for your home network, then look at running rtadvd instead -- that's the server complement to rtsold. You can also get addresses autoconfigured via a PPP link, but that depends on the specifics of your internet service, and you should ask your ISP for details.
