BT Begins Customer Tests of Carrier Grade NAT

Posted by timothy on Tuesday May 7, 2013 @01:27AM from the party-line-but-with-less-yelling dept.

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."

I've had to deal with this. by Gerafin · 2013-05-07 02:03 · Score: 5, Informative

Having to share an IP address with tons of people is absolutely, 100% a crippling experience. There are plenty of sites (newspapers, the site I get textures from, RapidShare, etc.) who limit their services by IP address. There's nothing quite like seeing messages about how your IP has exceeded the download limit on a website you've never visited before. Also: having to deal with bans when playing online games, as many are IP-based. The impossibility of hosting your own servers for games or other purposes. BitTorrent is nigh unusable. I would not pay a dime for this kind of a service, ever again.
