Earlier if someone was subscribed to static IP on airtel xstream fiber, they would get Public IPv4 even if they used PPPoE to connect. So we had 2 options to use internet:
1. PPPoE: You would get a Public IPv4 and an IPv6.
2. Static IP: You would use your assigned IPv4. No IPv6 in this case. ☹
Now the first option gives a CGNAT IPv4 (100.x.x.x in my case) along with a /64 IPv6. Can others check and confirm? You may need to disconnect PPPoE and reconnect to see changes.
I used to avoid using my assigned static IPv4 for normal usage for privacy. But now, the only option is either public IP or privacy, not both. You can still connect both simultaneously and set up routing to use either of the interfaces (PPPoE or static IP) depending on traffic.
