IPv6 Scope ID

• Scope ID is about IPv6.
• Scope ID is not relevant and not used for IPv4 connections.
• The IPv6 Scope ID is a number. It is not Text.
• What number you need to enter, has nothing to do with AADS, but depends on the Client PC.
• It is about the Client PC. It is not about the Server.
• What number you need to enter differs between Windows, OSX and Linux.

When an IPv6 connection attempts fails with some kind of "routing" error, then this "routing" error might be caused by not having entered an IPv6 Scope ID. Possible and hopefully the correct IPv6 ScopeID will fix this "routing" error.

Windows

Windows Vista and newer

• Usually you can leave the IPv6 ScopeID empty. Windows will figure out by it selves what the IPv6 Scope ID must be.

Windows XP and Server 2003

• Usually a correct value of the IPv6 Scope ID needs to be entered.

Obtaining the IPv6 Scope ID

Option 1:

• Contact the IT department that supports the Client PC and ask them about the IPv6 ScopeID for this Client PC.

Option 2:

• Open a dos-box, and enter the command ipconfig :

• The IPv6 Scope ID of this Client PC is 10.

Client PC with multiple network cards

If the Client PC has multiple network cards, it will also have multiple IPv6 Scope ID's. In such a case, see Option 1: Contact the IT department that supports the Client PC and ask them about the appropriate IPv6 ScopeID for this Client PC, such that this Client PC can connect with the AADServer(s).

OSX

Default an IPv6 Scope ID is required.

Obtaining the IPv6 Scope ID

Option 1:

• Contact the IT department that supports the Client Mac and them about the IPv6 ScopeID for this Client Mac.

Option 2:

• Open a Terminal and enter the command ifconfig

The IPv6 ScopeID of this Mac is 4.

Mac with multiple network cards

If the Client Mac has multiple network cards, it will also have multiple IPv6 Scope ID's. In such a case, see Option 1: Contact the IT department that supports the Client Mac and ask them about the appropriate IPv6 ScopeID for this Client Mac, such that this Client Mac can connect with the AADServer(s).

Linux

• Default an IPv6 Scope ID is required.
• If the AADServer and the Linux Client PC have both a Public IPv6 address, enter 14 for the IPv6 Scope ID.
• If the AADServer and the Linux Client PC have both a Local/Private IPv6 address, enter 2 for the IPv6 Scope ID. When IPv6 is used internally within a company, usually Local/Private IPv6 addresses are used for Client PC's, implying 2 for the IPv6 Scope ID.
• If either 14 or 2 do not result in an IPv6 connection from the Client to the Server, contact the IT department that supports the Linux Client/Distri and ask them about the IPv6 ScopeID for this Linux Client.

Linux Client with multiple network cards

If the Linux Client has multiple network cards, it will also have multiple IPv6 Scope ID's. In such a case: Contact the IT department that supports the Linux Client and ask them about the appropriate IPv6 ScopeID for this Linux Client, such that this Linux Client can connect with the AADServer(s).
