you should only see bbc.com if they think you're outside the UK so maybe the IP block you're on was non-UK before?

I'm on a static IP from Aquiss.

It was working fine for months, then for a few hours one day I was being redirected to bbc.com, and then it was back to normal.

I think that there must have been a glitch with the geo-location database used by BBC.

It's possible. I've not come across this issue but have lots of other fun with sites like Reddit that use very very bad firewall rules

I forgot to ask, did that happen over ipv6 or v4?

You may not know. Useful to get an idea if it did.. but you won't be sure usually.

I have v4+v6 enabled, but www.bbc.co.uk only supports IPv4 (i.e. A record, no AAAA record)

Aside: "bbc.co.uk" has both. But when you connect to it, it does nothing more than issue a redirect to "www.bbc.co.uk". Even from outside the UK.

bbc.co.uk is really where the MX records sit, and the BBC use messagelabs over v4 and v6.

www.bbc.co.uk and www.bbc.com map to the same IPv4 at fastly, and no IPv6 at all.

I assume BBC are using the CDN https://www.fastly.com/products/cdn

Sending E-mail to [email protected] is different to viewing the website, which was what this thread was about.

messagelabs is a widely-used spam filtering service. However, you'll notice that the MX records point to cluster1.eu.messagelabs.com and cluster1a.eu.messagelabs.com, both of which are IPv4 only (i.e. A record but no AAAA record).

It depends where you're looking from.

For me in the UK, both those names are CNAMEs which resolve to gtm-live.pri.bbc.co.uk. and that returns addresses 212.58.235/236/237.x which are within the BBC's own address space and announced out of the BBC's own autonomous system (AS2818).

I don't see any third-party CDN.

However, from the USA I see fastly:

They are clearly doing some geo-based DNS. The first name "www.bbc.co.uk.pri.bbc.co.uk." is being resolved to a different second CNAME which depends on where you're querying from.

But you're correct in saying there's no IPv6 anywhere; not even for bbc.map.fastly.net. (whereas I'm sure fastly does provide IPv6)

This shows that BBC have chosen to turn off IPv6 support, even where it would be just a mouse-click to enable it. Presumably they have user tracking code that only works with IPv4. Or they just hate IPv6.

Ugh.. thanks for highlighting, my IPv6 testing is from a server that I realise is in France. 😂 My only choice for high speed internet is IPv4 only.

I saw an interesting article in the last week that realised IPv6 “may not be needed” given things like NAT and CGNAT have happened to keep v4 working. Its a depressing thought.

The "internet of things" and self-driving cars will need IPv6.
