I was hoping to change my domain name that I submitted during the Enthusiast level. Can you help me?
Unfortunately, we don't allow the domain name change once submitted. However, You can reset your certification level back to the 'Explorer' level. Simply log into your account and visit ipv6.he.net/certification/reset_explorer.php. Please remember that once you set back your certification level, you must retake all the certification tests.
If possible, could I have the certification test reset?

I am really lost. Do you have any video tutorials or a certification forum available?
Yes, we have video tutorials available for each certification test and a certification forum. You may also send email to ipv6@he.net.
[Tunnel Broker]
I've tried to create a tunnel but did not succeed. Is there a basic guideline on how to set up a tunnel?
How to create a 6in4 tunnel (also known as a configured tunnel):
1. Visit our tunnelbroker.net site and log in.
2. Once you log into the site, click "Create Regular Tunnel" and
provide your IPv4 endpoint address and choose a preferable tunnel server
location. (Note: Your IPv4 endpoint address should be displayed on the
tunnel creation page)
3. After you successfully create a tunnel, visit your account's detail
page and choose your OS type to get example configuration commands.
4. Use the commands to configure your machine. Please remember, you
must have 'administrator' privilege to configure your machine.
5. Once you configure your machine, please browse sites like
ipv6.google.com or kame.net to test your IPv6 connectivity.
*Two important notes:
1. Your IPv4 endpoint address must be reachable via ICMP (Internet Control Message Protocol).
2. If you are using a NAT (Network Address Translation) appliance, please make sure it allows and forwards protocol 41.
What is Protocol 41?
Protocol 41 is one of the Internet Protocol numbers. Within the IPv4 header, the IPv4 Protocol field is set to 41 to indicate an encapsulated IPv6 packet.

I am confused. What is an IPv4 endpoint address?
An IPv4 endpoint address is also known as a public IPv4 address. Your IPv4 endpoint address should be displayed on the tunnel creation page. You may also visit a site like whatismyip.com to confirm the address.
My IPv4 endpoint address is dynamic. Can I still create a tunnel? If yes, what do I need to do when my IP address changes?
Yes, you can still create a tunnel even if you are using a dynamic IPv4 endpoint address. If your IPv4 endpoint address changes, you can either login to the tunnelbroker.net page and update your IPv4 endpoint address or use https://ipv4.tunnelbroker.net/nic/update which is designed to be used to update your IPv4 endpoint address.
While setting up a tunnel, I received an error saying "IPv4 endpoint is unreachable or unstable." What's wrong?
In order to create a 6in4 tunnel, your IPv4 endpoint must be reachable. Please go over your firewall settings and make sure ICMP is allowed.
I have a router that doesn't support protocol 41. Is there any other way to set up a tunnel?
If possible, get a new router that supports (allows and forwards) protocol 41. Alternately, you can either put the host in DMZ and secure it as best as you can, or by-pass your router to set up a tunnel.
I delegated reverse DNS to my own nameservers but it terminated at the he.net DNS servers rather than my delegated DNS servers. What am I doing wrong?
We don't delegate reverse DNS for the tunnel's Point-To-Point(PTP) /64. We delegate only to the routed /64 or /48s. Please make sure you did not delegate to the tunnel's Point-To-Point /64 by mistake.
