I have 2 virtual servers with Windows Server 2022 and Windows 11 client. When i create de Active Directory's domain and set the static IP on ipv6 (i cant do with ipv4, ipv6 is mandatory), dont resolve name, but the name host and the ipv6. I installed the Active Directory according tutorials of microsoft. I aplicate nslookup and this is the message:

DNS request timed out.
    timeout was 2 seconds.
Servidor predeterminado:  UnKnown
Address:  fc00::cafe:218:1

the ipconfig was:

 Sufijo DNS específico para la conexión. . :
   Descripción . . . . . . . . . . . . . . . : Intel(R) 82574L Gigabit Network Connection #2
   Dirección física. . . . . . . . . . . . . : 00-0C-29-41-DF-2D

   Servidores DNS. . . . . . . . . . . . . . : fc00::cafe:218:1
   NetBIOS sobre TCP/IP. . . . . . . . . . . : deshabilitado

thats my get-adddomaincontroller on powershell:

PS C:\Users\Administrador.DC1.000>  Get-ADDomainController -Identity "DC1" | Select-Object Name, Domain

Name Domain
---- ------
DC1  asir218.priv

dc1 is my computer name. When i do ping to the machine name, only ping to internal ipv6

  • And the DC config? – Greg Askew Oct 06 '22 at 19:35
  • is the standard. no OU, users , etc. no dns installed previously – Sergio Sánchez Oct 06 '22 at 19:44
  • The `fc00::cafe:218:1` address in in a reserved range that you should not use. The ULA range is `fc00::/7`, but the first half of the range (`fc00::/8`) is reserved for a global authority to assign. The second half of the range (`fd00::/8`) is available to be locally assigned, but the next 40 bits must be randomly chosen, giving you a `/48` prefix from which you can get 65,536 standard `/64` networks. (see _[RFC 4193, Unique Local IPv6 Unicast Addresses](https://www.rfc-editor.org/rfc/rfc4193)_.) – Ron Maupin Oct 06 '22 at 21:29
  • after all it was a bug from Windows Server, but thanks! Now i have DNS on ipv6 – Sergio Sánchez Oct 07 '22 at 17:42
