FWIW I think all ISPs that employ CGNAT are required by law to retain “NAT binding records” that are essentially this.

  I used to be an ISP and I'm not aware of any law like that in the US.

    Maybe a DMCA safeharbor thing?

      Nope

        I mean it may not be explicitly required by law but if you can't identify which customers broke other laws then aren't you opening yourself up to liability?

  There is currently no federal rule, law or other mandate for US ISPs to develop, construct or keep CGNAT translation records. The laws that apply in this area only apply to records voluntarily created by the network operator.
