I guarantee you that many, if not most at this point, of those numbers are no longer actually handled by that switch most of the time.
I suspect that there are more SS7 exceptions than default within that particular prefix which is why I chose it.
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. I am in frequent contact by a person that has a 917 NNX-XXXX-numbered telephone who spends a lot of time with a person that has a 408 NNX-XXXX-numbered telephone, and they both live in Metropolitan Boston The number I offer as my "home" telephone number "belongs" to a CO in a town 11 miles south of here and is not switched by the company that "owns" it. Knowing a telephone number or an IP address means that on a good day, you know how to make a connection with an instrument associated with it. Which may well be in the possession of Mrs. Calabash. -- sed quis custodiet ipsos custodes? (Juvenal)
