Question
You receive a call from a user who says that they can’t log in to a remote server, which only runs IPv6. Based on the output, what could the problem be?
C:\Users\Todd Lammle>ipconfig
Connection-specific DNS Suffix .: localdomain
IPv6 Address ...................: 2001:db8:3c4d:3:ac3b:2ef:1823:8938
Temporary IPv6 Address .........: 2001:db8:3c4d:3:2f33:44dd:211:1c3d
Link-local IPv6 Address ........: fe80::ac3b:2ef:1823:8938%11
Subnet Mask ....................: 10.1.1.10
Default Gateway ................: 10.1.1.1
Group of answer choices
There are two IPv6 global addresses configured. One must be removed from the configuration.
The global address is in the wrong subnet.
The IPv6 default gateway hasn’t been configured or received from the router.
The link-local address hasn’t been resolved, so the host cannot communicate to the router.

Based on the output provided from the `ipconfig` command and the symptoms described, let's analyze the situation.
The user is attempting to log in to a remote server that only runs IPv6. The provided `ipconfig` output shows the following detailed information:
- **IPv6 Address:** 2001:db8:3c4d:3:ac3b:2ef:1823:8938
- **Temporary IPv6 Address:** 2001:db8:3c4d:3:2f33:44dd:211:1c3d
- **Link-local IPv6 Address:** fe80::ac3b:2ef:1823:8938%11
- **Default Gateway:** 10.1.1.1 (which is an IPv4 address)
The critical point here is that the **default gateway is configured as an IPv4 address (10.1.1.1)**. In an environment that requires IPv6 for communication, such as connecting to a server that only supports IPv6, the device needs an IPv6 default gateway to route packets.
Given the analysis of potential answers available, the most appropriate answer is:
**The IPv6 default gateway hasn’t been configured or received from the router.**
This issue would indeed prevent Todd from being able to reach the remote server that only supports IPv6, as there would be no means to route IPv6 traffic adequately without an IPv6 default gateway.
