@Lolita_Magnum can excitel provide IPV6 to their users? What's the problem that IPV6 is so buggy. Sometimes people get double bandwidth and sometimes pages doesn't load. Is it simple for Excitel to configure OLT & start giving IPV6? What are the problems they're gonna face?

Excitel is giving out IPV6? I haven't received it yet.
To be honest, in all my life, unless IPV6 is incorrectly configured on the client's side, I have never really seen IPV6 issues ie, the page not loading issue. The only other reason is, that ISP handing out duplicates to multiple customers or the client didn't receive a new IPV6 configuration but the router assumes the old configuration.
The issue of double bandwidth is only visible in India and during the early days of IPV6 in the US. Since a lot of ISPs don't have IPV6 adoption to all of their customers, the server treats IPV4 and IPV6 as two different entities, but ISPs where there is 100% penetration of IPV6 don't have such issues ie Tata Sky AND JIO.
IPV4 and IPV6 are typically the same things just on different bits, so I don't know what scares people so much.
Hence, if it's configured well to allocate the IPV6 addresses on their side, it should work just fine with existing hardware.
When I was with I-ON the BNG used to hand out two different address of Public IPv6, one was b3 and the other b4, and both of these address was received by all the client via SLAAC. The problem was, b3 was internal only (ie can only be used to contact D-VOIS SERVERS and showed up in traceroutes and b4 was your public IP.) Hence, unless explicitly set in the firewall to not communicate using the b3 address, the internet didn't use to work. This is what airtel is doing right now too.

@Lolita_Magnum What you just said is true. Frankly I have faced no issues with Tata Play's (Sky) v6 network and probably because it is built ground up and not a retrofit that most others including Airtel are trying to do. However the question I have is if a majority of the 4 cellular providers (dunno about BSNL) do issue a v6 address as the main IP gateway and a CGNAT v4 for non v6 compatible sites, why don't we face issues browsing with a mobile phone or even as a hotspot?
@havoc ipv6 is not buggy per se I believe it is the retrofitting and implementation of this new addressing method that has caused issues. IPv6 is not exactly easy for those used to managing the old v4 scheme. And a switch over would be relatively complicated requiring some level of expertise in both v4 and v6 to do so. I figure only the commercial backbone providers like Airtel, Tata, Jio and Vodafone Idea have got this right given their larger resources while tier 2/3 ISPs may struggle. But it will happen as v4 address blocks get more and more expensive. From a commercial entity's PoV it makes no sense to spend on acquiring v4 blocks beyond a point.

@Chip except in Jio, I have not scene devices using hotspots receiving IPV6, and CGNAT has nothing to do with IPV6.
I also have experienced buggy IPV6 in Vodafone, with IP using completely different routes to reach the same service, (eg, Cloudflare, ipv4 at Chennai while ipv6 to Singapore.)
The main airtel AS9498 has a good implementation of IPV6 but the broadband subsidiary AS24560 is the culprit and they both work independently except when it comes to taking money.

@Lolita_Magnum I can confirm devices get a v6 address when using a mobile hotspot on both Airtel and Jio networks. Just tested it. The first 4 quartets of the device is the same as assigned to the mobile phone. Maybe a dynamic /64 PD? Dunno.
I think Airtel is probably accelerating the transition. Yes I am aware CGNAT is not related to IPv6 but I think it serves 3 purposes that serve to make the transition easy. Primary being compatibility with any remote v4 only sites and and secondary purpose possibly being to request a dynamic or static v6 over a PPPoE authenticated v4 connection till such time there is a transition to a full v6 internet across the world. The 3rd reason could be partial reduction of costs..a CGNAT v4 address is cheaper than assigning a full public IPv4 address. A look at Google's Ipv6 roll out status worldwide reveals it will take a long time and till that happens a dual stack is the way to go. Just my thoughts.

Yes, you are absolutely correct. I'm going back to Airtel postpaid by next week, maybe will check then.
Right now for Airtel broadband and many others, ipv6 is requested over pppoe.
I wonder how does Jio do?. Because I believe they don't use PPPoE.

When @Lolita_Magnum & @Chip both experts are discussing a topic we noobs should stay away from that discussion. As you guys are our seniors in terms of all this
