Yes, but you could also randomize your IPv6 address constantly too.

Downside of CGNAT and NAT at home is difficulty of getting some services to work, or hosting a server.

It still boils down to everyone gets an identifying number, whether it's an ipv4 address or an ipv6 block.

Any randomized ipv6 address from that block is still as "unique" an identifier as an ipv4 address.

Also, creating/using P2P applications. I needed to look up UDP hole punching and now I wish I hadn't.

out of curiosity, what did you end up going with? I had to host a UDP game server recently and couldn't find a good solution. If only ngrok supported UDP...

DMZ it and firewall up the host.

It was just research. I'm interested in audio&video over IP, I already had a good grip on HLS, RTP, and a few others, and wanted to dive into WebRTC, RTSP, etc. I don't know but all of this feels like there's a simpler solution (like HLS vs DASH) waiting to be discovered.
