I have ipv6 address fe80::21f:a4ff:fe91:2e44%4. This is the address of modem/router.
I am unable to open this address in browser to view the web configuration. I am able to telnet to fe80::21f:a4ff:fe91:2e44%4, view the console UI & can do settings.
I can also open 192.168.1.1(IPv4 address of modem/router) in browser.
I tried [fe80::21f:a4ff:fe91:2e44] in all browsers like IE, Firefox & Chrome. It was not possible.
