- CGNAT is criticized as a harmful practice in the ISP/telecom industry, delaying IPv6 adoption.
- IPv6 implementation is stalled due to lack of investment and planning by telecom companies, prioritizing profits over progress.
- CGNAT allows ISPs to conserve IPv4 addresses and increase profits by charging for direct connections, despite user experience and security drawbacks.
- NAT introduces complexity in identifying abusive or compromised devices, especially in residential settings where ISPs lack the resources or will to manage security.
- CGNAT exacerbates abuse tracking issues by sharing a single IP among hundreds, requiring detailed logs and procedures most ISPs don't maintain.
- CGNAT IPs are favored by malicious actors for anonymity, making abuse harder to trace and combat.
