Multiple DHCP Entries
Good Day,
Got a question which I am not sure about.
I got a Server 2012 Hyper V Host running 3 Virtual servers
6 NICS and 2 NIC Teams
Virtual Servers:
ServerA- DHCP DNS DC
ServerB
ServerC
ServerA has one virtual NIC and it is statically assigned IP address. IPv6 on this nic is disabled.
However on the DNS there are 3 entries showing for this server.
1. ServerA - Host(A) 10.11.1.12 static ( This is the static one on the only nic on this server )
2. ServerA - Host(A) 10.11.1.115 static ( Not sure where this is coming from. I tried deleting it and it comes back after some time. ?? )
3. Server A IPv6 Host (AAAA) - long mac address - 8/12/2017 11 PM
Shouldn't there be only 1 entry ?
The same issue is with couple of other severs. Either my concepts are not clear or it is something weird.
Thanks

Did you disable IP6 at the host level and the guest? Please confirm.
By disable, use item 1 and 2 (2012, 2008R2 - regardless)

If it comes back, let me know.

I understand IPv6 Address but where is the 2nd entry of 10.11.3.115 keeps coming back from ?
I deleted it yesterday and its back again!
SERVER A HOst A 10.11.3.115 static
See screen shot please.

There's no need to remove the AAAA record. It shouldn't hurt anything.
Can you run an ipconfig /all and see if the 10.11.3.115 is listed?

I ran ipconfig /all and it shows this address under PPP adapter RAS dial in interface
DHCP enabled ... no
Auto configure enabled .... yes
IPv4: 10.11.3.115( preferred)
Subnet 255.255.255.255
Default gateway : blank
NetBios over TCP IP : Enabled
Is it showing up because I am VPNed in remotely and RDP to the server ?
This made me think of looking into Routing and remote access on this server:
Under IP4 on RAS it shows 3 entries:
1. Interface: Loopback Type: Loopback 127.0.0.1 Operational Status: Operational
2. ***Interface: internal. Type: Internal: 10.11.3.115 operational status : Connected***
3. Interface: Ethernet Type: Dedicated Type: Dedicated
DHCP enabled ... no
Auto configure enabled .... yes
