Carrier Grade NAT centralizes millions of users behind shared IPv4 addresses so 95% of mobile traffic is behind CGN, breaking end-to-end connectivity and hindering attribution — Europol cases show investigations stall and 49 innocent people get questioned when logs are insufficient. CGN appliances ship with defaults and misconfigurations — an A10 device exposed with default password sits on the public net for over a year — and UPnP hole punching plus overloaded NAT tables cause mass outages. Real fix is full IPv6 deployment and dual‑stack logging.
