Re: phone fun, was GeoIP database issues and the real world consequences

I question whether (on a global scale) the odds are above 50-50 that a number (other than a test line) is served by the switch NANPA associates with the number.

The people on nanog are not typical. I looked around for statistics and didn't find much, but it looks like only a few percent of numbers are ported each month, and it's often the same numbers being ported repeatedly. I'd also expect to find a lot more porting in the highly competitive wireless industry than in the monopolistic wireline biz. R's, John
