Wrong Solution: Cisco Networking Academy Networking Essentials

IPv6 addresses can only be shortened once using the "::" notation.
The address 
fe80::6678:9101::34ab is invalid because it uses "::" twice, which creates ambiguity about how many zero blocks should be inserted.
The rule is that you can replace the longest contiguous sequence of zero blocks with "::", but only once in the entire address to ensure it can be uniquely expanded.

Please fix this

Hi @L057-50UL this is a technical forum mostly used by other people just like you - and there's nothing any of us can do about netacad.

You are trying to report an issue with some Cisco (third party) software.  The correct channel for reporting that is with the provider of the software - not here in a Cisco technical forum.

Login to netacad, click on your profile (top right) and select Support.  If you can't find the right option there then their standard answer is: "Your Instructor should be your first point of contact. They can answer your Networking Academy questions or contact the support desk for you. You can contact your instructor by using the message feature inside your course."

It looks like they don't let you contact support directly!

You could also try contacting them on their social media links at the bottom of their homepage.
