Hi, But after typing a link-local address, Firefox' message shows: Unable to find "www.fe80::213:49ff:fe04:507%8.com" It translated typed "http://[fe80::213:49ff:fe04:507%8]" to "http://[www.fe80::213:49ff:fe04:507%8.com]/". However, a global unique IPv6 address worked! I thought it proved that Firefox does not support link-local address. Thanks. BR, Yi-Wen Brian E Carpenter wrote: Yes, users need to configure our device via http, and if there's no well-known IPv6 address, how do users know which address to connect to? I have thought about a pre-configured link-local address; however, browsers such as Firefox does not support link-local address. Any suggestions?How come Firefox (or any other browser) knows how to *not* support link-local addresses? As far as I can tell, it does support them. Just don't forget the [ ] brackets. When I tell Firefox to connect to http://[fe80::1]/ it gives me an "unable to connect" message, but that's exactly what I'd expect. When I tell Firefox to connect to http://[fe80::21a:a0ff:fe4a:d680%5]/ (my own link-local address) it gives me a "server not found" message, which is also exactly what I'd expect, since I'm not listening on port 80.
