RE: SlashDot: "Comcast Gunning for NAT Users"
Hmm. I doubt Comcast is actually doing this - they are far too busy actually trying to build a network, out of the ashes of the @home debacle. However, even if they were, there isn't really anything wrong with it. We scratch our heads, collectively, when a large broadband provider goes chapter 11, but then oppose a pricing model that might be profitable. Now, if a provider was refusing to provide extra IPs, then I could see the problem. However, if a provider is willing to provide extra IPs for something reasonable like $5/month, more power to them. There are several good reasons why they might want to ban NAT: 1 - When you come to the stadium, you can't bring in your own hot-dogs. It's the same sort of thing - the hot dogs are subsidizing the ticket price. In this case, extra fees for things like IP addresses and extra email boxes, are the concession items. 2 - Support issues - supporting a largely clue-challenged user base, is hard enough without people slapping linksys routers in, then expecting the ISP to, defacto, provide support. Anyone remember when the only supported router for UUNet ISDN lines was the Pipeline 50? This was to (in theory) enable supportability 3 - NAT is wonderful, but we aren't running out of IP addresses that quickly, and NAT will break some applications. Large scale NAT is probably not the solution to future IP address exhaustion problems. Providers who do this are not being bad guys, because extra IP addresses cost less than the costs of supporting NAT boxes. If folks don't like this, they can become involved with ARIN and propose some bizarre price-support scheme for IP addresses, to encourage NAT, I suppose. 4 - This is, of course, an unenforceable policy (which is why I suspect it does not exist). However, it is very reasonable for a provider to refuse to support a customer with a NAT box, if the customer is buying a single user service. One usage policy I would support: never again seeing the word "slashdot" in the subject line of a NANOG email :) - Daniel Golding > -----Original Message----- > From: email@example.com [mailto:firstname.lastname@example.org]On Behalf Of > Martin J.
