Hello,
I would like to know if any service providers have built their access networks out using private IP space. It certainly would benefit the global IP pool but it may adversely affect users with special applications. At any rate, it sounds like good fodder for a debate.
I've got a friend who puts all of his internal servers, routers, and _customers_ on RFC1918 space and pipes them out thrugh a PNAT. Fairly small ISP - maybe 15 megabits of bandwidth - operating at the state local level. It's an interesting setup. Kind of fun. The stateful pnat functionality forces customers to specify exactly what inbound services they want, which can't hurt security. Every customer gets a /24 or greater, which helps convenience. On the other hand, everyone has a NAT in front of them, which means that they get clients who would have probably been putting a NAT in front of themselves anyway. I probably wouldn't use that setup myself, but then again, I subscribe to nanog... -Dave -- work: dga@lcs.mit.edu me: dga@pobox.com MIT Laboratory for Computer Science http://www.angio.net/ I do not accept unsolicited commercial email.
