> Is there an IPV6 for phone where we could have billions of throwaway numbers and use them as we see fit? Introduce a new country code that has 32 digit phone numbers and if you don’t accept those numbers, you don’t get our business? This is my question too. I've always thought something like you describe would be a pretty good, fairly practical approach to phone/text spammers just guessing numbers in valid area codes. Yet I never hear the FCC and other 'powers that be' talking about this kind of approach. They only seem to focus on ways of stopping spam at the source or network edge, which seems like a potentially intractable problem. Conversely, approaches which make it impractical to reach targets seem like they would be nearly impossible to circumvent. Yes, there are downsides in eventually displacing the 10-digit perma-number space but those could be mitigated by keeping the old number space but allowing users to quarantine inbound 10-digit comms that aren't already in their 10-digit address book (or don't have caller ID).
