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

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)_.)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
