Hi,
I am on a university network which I figure sets an ipv6 default route with DHCP. Output from ip -6 route:
fe80::/64 dev eth0 metric 256 expires 21318932sec mtu 1500 advmss 1440 hoplimit 4294967295
default via fe80::98c9:cc4d:2027:e183 dev eth0 proto kernel metric 1024 expires 65284sec mtu 1500 advmss 1440 hoplimit 4294967295
default via fe80::9c20:e192:7f04:9024 dev eth0 proto kernel metric 1024 expires 65183sec mtu 1500 advmss 1440 hoplimit 4294967295
default via fe80::38a6:a838:abb2:7b31 dev eth0 proto kernel metric 1024 expires 65361sec mtu 1500 advmss 1440 hoplimit 4294967295
I have trouble accessing a certain domain hosted on the university network. Some elucidating feedback from a professor who doesn't have the time to really help me troubleshoot:
"The problem seems to be that the IPv6 default route points to the link-local fe80:: network. <xxxxxx> has a global address which surely does not exist on the link-local network. But the kernel, likely forced by the default route, throws out a connection request to this link and then waits for a timeout...I assume when you remove the IP6 default route, the problem disappears. "
And indeed, when I sudo 'ip -6 route del default' a few times, my problems accessing that domain disappear.
I would like to know how I can permanently disable the ipv6 default route, since this is getting annoying. And I really don't have much of a clue how to do this :-)

Have you tried this?

Thanks, that works and is a good solution considering I don't really use ipv6
