I'm on dual stack IPv4/IPv6. I'm using Firefox and have the https://github.com/HostedDinner/SixIndicator add on.

From the link in your first post, when I click Mail I get the attached. I've put the mouse over the indicator to show the IP of the current page.

With IPv4 and IPv6 in operation, I can indeed get the webmail login prompt - followed that link on the left. Don’t know a username/password so can’t test it any further of course. This was on an iPad with Safari.

Exactly the same as jelv.

Hi

I do think it is a IP block but using pure IPv6, I can access the following sites at AOL as defined by ping tests below

Many thanks

John

It is looking like this is an IPv6 issue - I'll try setting my Zyxel to IPv4 only when I get a chance.
Thanks for all the help everyone.  :)

Rather than disturb the whole household by changing the router settings, can't you just turn off IPv6 on your PC?

Jelv is it possible to use the Windows firewall to block IPv6 going to just that one website?

That might get complicated as there would probably be a number of urls/IPs. If DNS lookups gave IPv6 addresses which were then blocked I don't think anything new would be learned. Easier to just disable IPv6 on the PC as a quick test.

Trying via the free VPN built in to a browser (e.g. Opera) might be worth a shot.

Bear in mind BT don't have IPv6 DNS servers so you need IPv4 to get IPv6 addresses

It is an IPv6 issue as I've just found a Firefox setting (network.dns.ipv4OnlyDomains) that allows you to force certain domains to use IPv4.
Putting "aol.com,aol.co.uk" into this allows me to get to the mail login.
Stupid AOL  :rant:

What I still don't understand is why this works fine for my father-in-law who is using a BT Hub2 which I assume is IPv6 enabled? Next time I'm at his house I'll take a look.

As nobody else is having issues accessing the login page via IPv6 I suspect it's stupid BT :rant: not stupid AOL.

Hi

Sorry Jelv, no issues connecting IPv6 using BT IPv6 here

The workaround is using IPv4, which was suggested early in thread and I still think it maybe a block

The easiest way to test as a rule, is to ping first bbc.co.uk - to make sure it is IPv6 resolution and ping return then ping same as my pings.

If ping fails, check the DNS resolution, if it cannot resolve, it is usually a DNS issue but of it resolves ok, then it is usually a block.

Many thanks

John

Here's my ping results. Interesting that the last two AOL ones resolve to IPv4 addresses, which I assume is the dualstack fallback working?

> which I assume is the dualstack fallback working?

I don’t know what that means. The dns lookup for aol.co.uk gives principally five A records ie IPv4 addresses and that’s it, no IPv6 addresses at all. In this case the outcome is solely controlled by the DNS records. Now amongst those five A records an application must make some decision as to which one of those addresses to talk to. And say there are both IPv4 and IPv6 records it’s only the same thing; some application must choose either an IPv6 address to talk to or an IPv4 address.

Are you thinking of the "happy eyeballs" algorithm in web browsers perhaps? In that case the answer is no.

We really need to look at what all the many results of the dns lookups are before using things like ping which just have to guess what to do when they get several completely different results back, otherwise the results just get very confusing.

I don’t know what that means. ...

I was referring to my Zyxel VMG-8924 being set to "IPv6/IPv4 DualStack" in its network settings. This clearly allows it to use both IPv6 and IPv4, but exactly how that works I don't know as I'm no expert in these things.
