121  <div class="question">
122    Q: Can you fix my VPN?
123  </div>
124  
125  <div class="answer">  
126    No, I can not fix your VPN.
127  </div>
128
129  <div class="question">
130    Q: How does this test work?
131  </div>
132
133  <div class="answer">
134    The test is entirely client-side javascript. To determine reachability, a series of ajax requests are made from the web server, using various DNS names that force the use of IPv6 only, or dual stack, or other such scenarios. The pass/fail of such fetches, as well as how long they take, are taken into account.
135  </div>
136
137  <div class="question">
138    Q: Why is this web site reachable via IPv4 only?
139  </div>
140
141  <div class="answer">
142    You're right, there are no AAAA records, intentionally. A percentage of users are unable to browse sites that are dual-stack. If the users can't connect, then they can't be told they have a problem. This is a big problem facing content providers today; of which, I work at one for my &#36;dayjob. As such, the main test page requires IPv4 (either native or translated).
143  </div>
144
145  <div class="answer">
146    At some point, when the percentage of "broken" users has gone significantly down, I'll consider making test-ipv6.com dual-stack. At last check, March 2017, we still see 0.2% broken visiting test-ipv6.com. And we still want them to understand their situation.
147  </div>
148
149  <div class="question">
150   Q: I run a production IPv6-only network. Without IPv4. My users can't reach test-ipv6.com.
151  </div>
152  
153  <div class="answer">
154   Send email to [email protected]. If your IPv6-only network has dedicated name servers, or a dedicated BGP ASN, jfesler will enable AAAA records for test-ipv6.com for you.
155  </div>
156
157  <div class="answer"> 
158   If you don't meet the above requirements, you can visit http://ipv6.test-ipv6.com (IPv6-only) or http://ds.test-ipv6.com (IPv4+IPv6).
159  </div>
160
161
162  <div class="question">
163    Q: What do you mean by broken?
164  </div>
165
166  <div class="answer">
167    A percentage of users today have IPv6 enabled, but are either using a public tunnel that is currently giving poor performance; or otherwise have a route that is installed but broken or suboptimal. However, because they have a route at all, in many cases the address selection algorithm of RFC3484 will pick using it, and trying to use this broken route. It can take towards 75+ seconds before the browser gives up!
168  </div>
169
170  <div class="answer">
171    From the perspective of a user with these conditions, a web site offering both A and AAAA DNS records (ie, "dual stack") will appear to time out; and the user will move on to another site that offers a similar product. This is the quandary content providers have.
172  </div>
173  <div class="answer">
174    If we detect that you will have problems reaching dual-stack web sites, we recommend you see the <a href="broken.html">Broken User FAQ</a>. It provides several steps to try and identify your root cause for being broken; and barring that, what you can do to disable IPv6 until your ISP offers native IPv6 connectivity.
175  </div>
176
177  <div class="question">
178    Q: Why did your stats say you already have IPv6-only users?
179  </div>
180
181  <div class="answer">
182    They went to <a href="http://ipv6.test-ipv6.com">http://ipv6.test-ipv6.com</a> .
183  </div>
184
185  <div class="question">
186    Q: How valid are the stats?
187  </div>
188
189  <div class="answer">
190    They do not represent the average web consumer. Visitors to this site are self-selecting. The intent of this site is to not provide stats, but instead to inform the user the level of readiness for the world to move to IPv6 (with or without'em!). As such, stats found here will be completely different from an average content provider.
191  </div>
192
193  <div class="question">
194    Q: How does your test differ, from what the content providers are doing?
195  </div>
196
197  <div class="answer">
198    Content providers are gathering metrics of broken vs non-broken users, in an aggregate form. They are not at this time actually giving the user feedback as to the user's current state. Those metrics will principally drive the business decision of when to start publishing sites over IPv6, versus remaining IPv4 only. IPv4 only for some content sites really is an option; it has a handful of downsides, but the expectation is that everyone will always be able to reach IPv4, in some fashion.
199  </div>
200
201  <div class="answer">
202    This site, on the other hand, is intended to help the user understand their current state, and what that state possibly means to them.
203  </div>
204
205
206  <div class="question">
207   Q: What are your data sources?
208  </div>
209
210  <div class="answer">
211 
212   The following data sources are checked daily, and are used to convert IP addresses into Internet Service Provider names. <ul> <li><a href="http://routeviews.org">University of Oregon Route Views Archive Project</a> provides hourly views of the Internet routing tables. <li><a href="http://bgp.potaroo.net/asn.txt">http://bgp.potaroo.net/asn.txt</a> is a curated list of ASNs to internet service provider names. This is provided by Geoff Huston, a well respected researcher from APNIC. </ul>
213
214  </div>
215
216  <div class="question">
217    Q: What features have been added/removed?
218  </div>
219  <div clsas="answer">
220    <ul>2017: Added TLS (https) support </ul>
221    <ul>2022: Removed links to swap http/https. Browsers are starting to forcefully upgrade to https.<

221/ul>
222    <ul>2022: Removed tunnel detection by comparing ASN numbers. More service providers are using a different entity for IPv4 vs IPv6.</ul>
223    <ul>2022: Removed direct IP checks, NAT64 detection, Teredo detection. This is for support cost reasons; too many people complain about the tests that are skipped in https mode, and we're seeing browsers forcefully upgrade to https.</ul>
224  </div>
225
226  <div class="question">
227    Q: Do you actually read the feedback?
228  </div>
229
230  <div class="answer">
231    <p>
232    Yes, I do. Thank you! Note that I can only follow up with you if you do leave contact information. While I am still grateful for feedback without contact information, I will be unable to reply with any answers if you asked for them.
