I want to configure ipv6 for my connection, have received ipv6 address but gateway is not available, not even sure about my gateway being noida or delhi, but definately one of them. Can someone share gateway details?

It is set via router announcement (RA) and is done by your router. The client device will obtain it automatically via DHCPv6 or SLAAC. IPv6 gateway needs no manual configuration.
 
I don't think you're supposed to manually configure whether it's static or not. Looks like you're asking wrong question since your router already got an address. If you put everything in relay mode it should work if it's supposed to work, otherwise you may need to setup NAT66 because some ISPs offer /64 to the device dialing to them and forget about it (I think, could be consumer routers' fault too, IDK).
 
@nishantt6969 Static IP address with what prefix? /64? If yes, then the last 64 bits of the address will be automatically generated by the devices. It is mostly likely a temporary IPv6 with the 1st 64 from the ISP and the last 64 from the device using IPv6 RA. This is done for privacy reasons on Windows and mobile devices. Privacy extensions are enabled by default on on Windows and can be disabled.

IPv6 has common features with v4 but operates very differently in practice. As mentioned before the gateway is provided automatically by the router. In my case I have pfSense running and my PC and other devices get fe:80:: followed by the last 64 bits of the router's LAN IPv6 address that is assigned by using track interface options for that interface. I don't think all these options are available in the ISP supplied router. It is done automatically.

In other words connected devices use the router's LAN interface as the gateway just like in IPv4. The difference here is it is automatically generated. Inputting any of these options manually can result in connectivity issues.
 
Uhh..

This isn't correct. fe80::/10 is IPv6LL. It doesn't get assigned by router (but the host itself) or has anything to do with it (well in this context).

Yes, I am aware that is a link local address. What I referred to were the last 64 bits being attached to the link local address of the device. Those are the last 64 bits of the router's LAN interface. For e.g. on this desktop machine the gateway is <edited> while the router's LAN interface routeable IPv6 address is 2402:e280:<edited>

Yes, it is based on the MAC and has been edited. It is on pfsense which does all this automatically must see if they can use v6 privacy extensions. @wheatbread if you're skilled on Linux/FreeBSD can you explain how this can be done?

EDIT: Did a bit of reading on the pfSense forum and it was there. The system has been set to use privacy extensions. Thanks for the alert. Silly of me to have missed out on that.
