Note

The order of the two first blocks seems to matter. If you put the randomizeidentifiers block before the privacy block, then Windows will still use randomizeidentifiers...

 

 

Remove address

In case you want only manually configured address, but started out with EUI-64, you might need to remove some addresses manually:

For servers it makes sense to have statically configured addresses, and avoid dynamic/privacy stuff as much as possible.

However, you might have started out with privacy stuff on, and have to remove things: 

Code Block

C:\Users\Administrator>ipconfig /all

To remove the EUI-64 address 2001:610:148:babe:20c:29ff:fedb:af95, first find the interface number:

 

Code Block
C:\Users\Administrator>netsh interface ipv6 show addresses
Interface 1: Loopback Pseudo-Interface 1
Addr Type  DAD State   Valid Life Pref. Life Address
---------  ----------- ---------- ---------- ------------------------
Other      Preferred     infinite   infinite ::1
Interface 10: Local Area Connection
Addr Type  DAD State   Valid Life Pref. Life Address
---------  ----------- ---------- ---------- ------------------------
Public     Preferred  29d23h57m39s 6d23h57m39s
Code Block
languagepowershell
netsh interface ipv6 delete address "Local Area Connection" 2001:610:148:babe:20c:29ff:fedb:af95

Manual     Preferred     infinite   infinite 2001:610:148:babe:cafe::3
Other      Preferred     infinite   infinite fe80::20c:29ff:fedb:af95%10

The trick is to disable autoconfiguration on that interface:

Code Block

C:\Users\Administrator>netsh interface ipv6 set interface 10 routerdiscovery=disabled
Ok.

Now it should be gone:

Code Block

C:\Users\Administrator>netsh interface ipv6 show addresses
Interface 1: Loopback Pseudo-Interface 1
Addr Type  DAD State   Valid Life Pref. Life Address
---------  ----------- ---------- ---------- ------------------------
Other      Preferred     infinite   infinite ::1

---------  ----------- ---------- ---------- ------------------------
