I have a friend who is in SprintLink as a customer and he has VPN routers that this would take down... He called and they will route it.. Also, I got an offlist reply from a network services tech, and he said they would route if a customer requests it.....

However, there was a link: http://www.sprint.net/faq/serialip.html That explains that you can keep using your ptp IP if you request it, but in either case, they will no longer route their end of the IP.

Interesting. Did any of you note last month or so that Sprint US came out with a notice that they are no longer going to router /30 ptp subnets unless the customer specifically asks for it?

Could that be why 10.x.y.z is showing up here?

Sprint??? you out there?

Heh... Check out Comcast. A large part of their network uses rfc1918:

Is there a site to "report" networks/isps that still leak rfc1918 space? By leaking I not only mean "don't filter", but actually _use_ in their network?

If someone is keeping a list, feel free to add ServerBeach.com. All traceroutes to servers housed there, pass by 10.10.10.3.
