How to disable DHCP ipv6 on Cisco DPC3939B? DNS settings?
I need to do a new fresh install of Windows Server 2012 R2 Essentials on a new small office server.
I need the server to be my Domain Controller and DHCP (not the router).
Before installing, I need to disable DHCP of both ipv4 and ipv6 on the router.
Obviously ipv4 is straight forward, but ipv6 is NOT.
I am not at the router right now, so cannot remember the exact settings, but I think BOTH Stateful and Stateless were checked? I don't know what these mean and is quite easily confusing.
Stateless (Auto-Config) is checked (but grayed out, cannot change?)
Stateful (Use Dhcp Server) is checked
BOTH Assign DNS manually for IPv4 and IPv6 are UNCHECKED.. should these be checked and filled in with exactly what? IPv6 entries are obviously crazy here..have NO idea what to do with IPv6.
Something about Stateful being like static? And Stateless being like DHCP? Is this correct?
What should exactly be set here to disable DHCP ipv6?
I think the first setting to the far left was grayed out but checked.
Do I even need to mess with the router's ipv6 to have the Server to DHCP and as a DC and for Active Directory? I understand that it is time to start using ipv6, so not sure I need to be cutting all that off? But do not understand ipv6.
Also, while in here, do I need to set the DNS MANUALLY also? And for BOTH ipv4 and ipv6?
What primary and secondary DNS servers do u enter here?
Do I enter the dns of my server address as primary? And maybe secondary as google's 126.96.36.199 or openDNS dns? Or do the Comcast dns go here? I.e. 188.8.131.52?
Or do I setup up a forwarder to the the comcast primary & secondary dns on the WS2012R2E server?
Thank you for any help.
