I'm trying to get IPv6 working for a big school project. I have a Dualstack line with an IPv6 ready modem. The server and client get there IPv6 automatically, but when I want to use static ULA addresses I can't connect to the IPv6 DNS server 2001:4860:4860::8888. I just want to give an easy to remember IPv6 address so that I can work with those addresses easier inside my network.
The modem has already got an ULA address which is fd00::c225:6ff:feb5:9595/64. I gave my client an IPv6 adres which is fd00::21/64 and the gateway and dns are fd00::c225:6ff:feb5:9595 which is the modem/router. This is somehow not working.
My question is what am I doing wrong and is my idea even possible?
Thank you in advance.
