We give ipv6 addresses, but we dont allow ipv6 packets.

ACT does not officially support ipV6 in Chennai. However, they do offer ip6 addresses when requested by your router. The only issue is that they don't allow ipv6 packets to pass through. Only ipv4 is allowed.

I found this by mistake one day, when I was playing around with my router and suddenly it got an ipV6 address issued from ACT. However, all my connections were still ipv4 and running tests on Test your IPv6. failed.

Bewildered I called ACT who's tech team was like we are handing out ipv6 addresses but aren't allowing packets through.

I am unable to wrap my head around this. I have tried multiple times to get through to someone higher than the engineer on the backend team to no avail.

Why would a company that has the infrastructure ready, prevent users from actively using them? It would be a different matter if they don't issue ipv6 anywhere else, but they do so in Bangalore and other regions where they have setup shop recently.

I'm posting here out of frustration and looking for solutions to get ACT to actively enable ipv6 connections in Chennai.

This has been going on too long. I'm tired of being stuck behind a CG-NAT address.

Providers like Airtel and BSNL are already ipv6, it looks like ACT doesn't give 2 hoots about one of their largest user bases. I would love to change to Airtel, but ACT has the best speeds/pings since the ONT switch is right above my house and not to mention, their plans are price worthy.

How or what can I as a consumer do to enable this?

On an unrelated note, how do I find a local ISP and whom do I ask? Everyone in my apartment uses ACT only and I don't know anyone in my area who uses cable TV. Tried goggling which didn't work.
 
Not the length.

Example.
This is what you should receive for LAN 3211:0:0:1234::/64
And, one for the WAN side, 3212:0:0:1235::1/128
 
I seem to have only the LAN side prefix.
Router is Archer C6 v4.
2406:7400:c1::/64 - this is the LAN side with ND proxy and this 2406:7400:c2:c794::/64 with Prefix Delegation.

On the WAN side, I only have the Gateway, DNS, link local addresses and the Global Address.

Would sharing any of those help?

I also don't understand the difference between ND proxy and Prefix Delegation, I'm learning ip6 only now.
 
This is the router page at ipv6 wan. I've stuck out the Global address.

That is a good point.

When using pppoe, it does not get connected at all.
And no global address comes up.

This was the point I called ACT and they told me they'll check and get back, which when they did, they said pppoe is disabled and no packets are allowed on ipv6.

When not using pppoe, I atleast get a global address.

Global address means nothing.

Your data stream is meant to go via the PPPoE. On the Broadband Server from ACTs perspective, that is the only valid packet on their interface.

It is possible that it is still in their testing phase for your location, or it is an unauthorized broadcast. This is possible, if the last mile is copper.
