Do you have the IPv6 box ticked on your DC NIC?

[TwistedHelixis]

I look after a few primary school networks. Some I have setup from scratch and some I have inherited.

 

I have just noticed that some of the DCs have the IPv6 adapter protocol ticked, while some do not.

 

Internally each school only uses IPv4

 

Each of the DCs also runs DHCP, DNS etc

 

Should IPv6 be ticked on the DC or not?

 

If yes, am I OK to leave the settings under properties to auto assign?

 

Thanks

It should always be ticked on a DC. Can't remember why, can remember that it caused issues when off. No reason not to have it turned on.

It should be left on even if you’re not using it. I have had issues in the past. WSUS was an example.

Very much so.

In DHCP > IPV6 > server options, some of the sites have nothing in this section, while others have ::1 & Domain search listed.

 

If I click on DHCP > IPV6, it asks me to setup a new scope, so none of the sites has an IPv6 scope running.

 

Which of the sites has the correct setup, based on previous posts.

We have IPV6 off on everything inc all DCs no issues seen apart from some less errors in event viewer! Edited October 24, 2022 by CrootUK

Instead of me writing what MS has already committed to paper the above spells out what is and what is not supported, and I will add this if you open up an MS premier call the first thing your going to get told is get your house in order (or ipv6 in this case..) and call us back.

One of the things I remember is that with IPv6 disabled ADUC used to take ages to open. Turning it back on fixed that. If MS themselves say leave it on, that’s good enough for me.

get your house in order (or ipv6 in this case..) and call us back.

I have already enabled IPv6 on the NICS and working through a couple of other sections.

 

So, if I have IPv6 enabled on the DC / DHCP server NIC, but don't want to use DHCP for IPV6 addresses, why do some of the schools I have inherited have the following under DHCP > IPv6 > Server options, and some have nothing?

 

My question, if I am not using DHCP for IPv6 and have no scopes set, should I still have the above filled out or not? Just trying to workout why some of the schools that I inherited have this section filled out.
