In a normal IPv4 network, I can go into any browser such as Firefox and browse a server on a IPv4 address not hosted on port 80: (add http:// - Super user stops "new" users from adding links)192.168.42.6:8080/ This accesses the server on Port 8080 on 192.168.42.6. However, if I try this with a IPv6 IP, I get no luck. This tries to access port 8080 on fe80::520:ff0f:ece0:1 : http://[fe80::520:ff0f:ece0:1]:8080/ Firefox will automatically "fix" this URL to: http://[www.fe80::520:ff0f:ece0:1.com]:8080/ which does not help me access it at all. So either I am doing something really wrong OR there's something really wrong with IPv6. Couldn't find anything that even remotely helped on the Internet. (And yes, there is a server running on the IPv6 in question)
