>Unless you like low-latency video chats. Or online gaming. Or VPNs. Or reliability. Or remote desktop. I have all of that with CGNAT. >Fundamentally, TCP won't allow more than 64K connections from one IP to a single port on another IP. That's a hard limit on the number of users behind a NAT of any kind who can simultaneously connect to a given service on a fixed port. Right now my ISP's resolvers are returning exactly two IPs for google.com. If it were infected with CGNAT, at most 128K of my ISP's customers could use Google at the same time. The real number is much smaller as fetching a web page typically opens lots of connections. First, Google has tons of IP addresses, not only two. Second, ISPs with CGNAT servers don't have only one for all customers.
