I deleted that address while I was just experimenting with some different configurations, thinking I would put it right back. Didn't work out.
pinging "up the chain" is a good suggestion; I find that, while I can't ping a url from my pc like "ipv6.google.com" nor access it from a browser, I am able to ping some ipv6 addresses. Here is a traceroute of pinging the HE server ipv6:
Tracing route to 2001:470:a:523::1 over a maximum of 30 hops
1 <1 ms <1 ms <1 ms 2001:470:b:523::2
2 34 ms 33 ms 34 ms 2001:470:a:523::1
Trace complete.
And while it is ridiculously hard trying to find a ping-able ipv6 address anywhere out on the wider web, I did find this address from Google DNS, and did a traceroute on it:
Tracing route to 2001:4860:4860::8888 over a maximum of 30 hops
1 1 ms <1 ms <1 ms 2001:470:b:523::2
2 36 ms 36 ms 36 ms 2001:470:a:523::1
3 35 ms 43 ms 34 ms 2001:470:0:9b::1
4 35 ms 35 ms 34 ms 2001:470:0:130::2
5 38 ms 57 ms 63 ms 2001:4860::1:0:610
6 34 ms 34 ms 34 ms 2001:4860::8:0:699a
7 41 ms 41 ms 69 ms 2001:4860::8:0:61de
8 42 ms 61 ms 41 ms 2001:4860::2:0:ab
9 * * * Request timed out.
10 42 ms 42 ms 41 ms 2001:4860:4860::8888
Trace complete.
So it looks like it gets out there. Putting this address - [2001:4860:4860::8888] - in a browser gives me nothing though, but that may be just because there's nothing there that a browser could really read.
I can confirm that this MikroTik does support IPv6.
My professor has been unavailable this last week, though I have talked to him briefly about this problem. I will be talking to him again tomorrow, but unfortunately since this lab is still under development (hence my work), he hasn't had a lot of the answers I've needed thus far. He's pretty knowledgeable, don't get me wrong, but not on the details of this particular process.
Okay, here's a good one. Maybe this will help. I can ping 2607:f0d0:1002:51::4 from my PC (which is supposedly
www.cyberciti.biz), but putting http://[2607:f0d0:1002:51::4]/ into my browser doesn't work. Does that help anyone know what's going on? When I was on a network that supported ipv6 without any need for a tunnel, I was able to get on to websites like ipv6.google.com, so it's not like it's browser related. Very strange.
