Does Tata Sky BroadBand provide public ipv4 address if willing to pay extra?

They can allocate static public IPv6 free of cost, no public IPv4 even if you are ready to pay for it.
 
@messyhanibal no, they do not offer static IPv4 public or CGNAT. And no dynamic IPv6. IPv4 is CG NAT dynamic and IPv6 is static. I spoke to them yesterday. Still thinking if I should take a public IPv6 even if free. They also confirmed you can revert to IPv4 if you wish.
