Submission + - BT Begins Customer Tests Of Carrier Grade Nat (

judgecorp writes: BT Retail has started testing Carrier Grade NAT (CGNAT) with its customer. CGNAT is a controversial practice, in which IP addresses are shared between customers, limiting what customers can do on the open Internet. Although CGNAT goes against the Internet's original end-to-end principles, ISPs say they are forced to use it because IPv4 addresses are running out, and IPv6 is not widely implemented. BT's subsidiary PlusNet has already carried out CGNAT trials, and now BT is trying it on "Option 1" customers who pay for low Internet usage.
