Re: ISPs react to the Dangers of CGNAT Even if they did give them all up it's just a minor stop gap. Maybe buys a couple more years.
said by anon anon :Which would help now while they try to get IPv6 fully rolled out. Aside from the old Class A /8s there are some more /8s in the Class E range that are not being used. The Class Ds are still needed for the inefficient IPv4 Multi-Cast (which is much better supported by IPv6 Multi-cast since there are not the redundant sessions that IPv4 Multi-Cast needs).

said by RARPSL:No, it would allow more procrastination. Most ISPs didn't begin actually moving to IPv6 until the threat became real and in their face. Reallocating IPv4 addresses will only allow them to relax their migrations. The Internet needs to move and be done with the migration soonest.
