Hi,
I recently been upgraded to FTTP. I have an IPv4 static /29 block, which (eventually) was successfully ported to the new connection. I am using a 3rd party router. I went in yesterday to configure IPv6... but the DHCPv6 client was not able to acquire a prefix.
So typically (if you didn't know) with IPv6 you get a large bunch of addresses under the same prefix. For business, typically a /56 or maybe a slash /64 prefix. This is normal. IPv6 space is unlikely to run out until we leave the galaxy. You can either statically configure this, or ask a DHCPv6 for it - which would ideally hand you your static reservation.
I can see the PPPoE session is up with IPv6 link-local both sides, but my DHCPv6 client got IA_PD response of Status NoPrefixAvail from the BT side in response to my SOLICIT. i.e. Their server said you can't have a block of IPv6 addresses. I mean, there are only 340 undecillion of them, perhaps BT are worried about running out.
"No problem", I though naively, it must be that I need to statically configure the prefix, or sign in with non-default credentials Currently I use "btbusinesshub@business.btclick.com" which works fine with the IPv4 static addresses.
So I contacted BT via the online chat.... after about an hour of trying I got a response. What was... that I had to choose EITHER a static IPv4 block OR a static IPv6 block, not both.
Now surely, this can't be true; since if so BT clearly doesn't understand how the internet works...
Sadly, the session then broke so I couldn't continue the conversation. I tried to phone in, but after waiting for 40 mins it became 6pm and I got disconnected...
Can anyone confirm if this absurdity is true, and if (hopefully) not, how best to go about getting a static IPv6 prefix?
Cheers,
James.
