As I stated before, my hosting company did tell me to go to VPN in order to get IPv6

But again, as your link shows, it seems like to use the tunnel, you need to have native IPv6.
I only have IPv4 and could create an mappedIPv6 or IPv6to4.
I was hoping to be able to use these as my IPv6 but it does not seem feasible from what I gather?

You seem to be putting the cart before the horse here.

First, whether or not you have IPv6 for the computer you use, whether native from your ISP or via an HE.net tunnel really has no bearing on your website. The two are presumably in completely different locations, so the solutions for one are not the solutions you'd choose for the other.

Aside from that, why do you think that you need an IPv6 address for your website? Before trying to figure out solutions to this it would be useful to know why you are going through this process.

I use my computer when I want to access the internet.  I realize that this has nothing to do with my website.
I had a public IPv4, but I noticed lately that I also had an IPv6 address, which my ISP no doubt gave me in order to be able to connect to IPv6 sites.  I completely understand this.

Now, with respect to my website.
Yes, it is at a different location, is part of shared hosting and at my hosting company location somewhere in the US.

The following is why I started enquiring about IPv6.

We are using PHP and fsockopen() to check if a host is available. It works great for standard ipv4 addresses, but recently we started adding ipv6 addresses and it fails. According to the PHP documentation for fsockopen() we simply just need to enclose the ipv6 address in brackets for ipv6 support.

fsockopen('[2001:41d0:2:381::14]', 80, $return_error_number, $return_error, 10);

However, we are always getting:
"Network is unreachable"

I then checked my PHP on my website using php():
It stated ipv6 was enabled.

As a test, I ran the local host in ipv6:
[::1]
This worked with fsockopen()

Then I decided to try an ipv4 from yahoo.com and mapped to ipv6:
98.139.180.149 ===> [::ffff:628b:b495]
This worked with fsockopen

Just for the hell of it I used [::] and it worked with fsockeopen

As I stated, after some more research, I learned more about mappedIPv6 and also IPv6to4 which is supposed to be used in Tunneling
Using my IPv4 website address I created a mappedIPv6 and an IPv6to4 and added them both to my DNS file as AAAA records.
When I did a DNS lookup, both IPv6 addresses showed up.

Again, I was not able to connect to IPv6 addresses with fsockopen.
I then started reading a lot about tunnelling, gateways etc. to connect IPv4 to IPv6.

What I need to do then is reach IPv6 addresses from an IPv4-only network with fsockopen.
Sometimes I only know the IPv6 address of the website not the domain name so I need to be able to check if there is a connection using IP address only.

Hopefully I have explained why I am going through this IPv6 process.

Yes, to connect to any IPv6 based resources on the internet, including websites, you'll actually need to be using an IPv6 address, whether a native address, or using one of the "transition technologies" such as tunneling, or one of the others that you mentioned.

Unless you do a lot of sophisticated coding, or pay for some sort of dedicated virtual machine (which get's very expensive very fast) its going to be very difficult, if not downright impossible, to make this connection without an IPv6 address assigned by your webhost. I don't think it would be practical for you to set up any of the IPv6 transition technologies such as tunneling, 6rd, or many of the other ones out there, because of the limited controls you'll have over the web server itself.

Your best bet is going to be finding a webhost that offers hosting on both IPv4 or IPv6. I know they are available, I just haven't had a need for one myself since an IPv4 based website meets all of my needs. Unfortunately I don't know your market so I have no idea how practical that will be for you. I can't see any reason for you to get any sort of VPN service unless you actually need to host VPN, which this doesn't sound like.
