Dual stack IPv6 for IPv4 depletion

Thu Jul 9 20:56:07 UTC 2015

Huh, since when does ANY application care about what size address allocation you have?  A V6 address is a 128 bit address period.  Any IPv6 aware application will handle addresses as a 128 bit variable.

Does any application running on IPv4 care if you have a /28 or a /29?  In fact the application should not even be aware of what the net mask is because that is an OS function to handle the IP stack.  This argument makes no sense at all since every application will be able to handle any allocation size since it is not even aware what that is.  Any IPv6 compatible OS will not care either because they would be able to handle any number of masked bits.  No app developer has ever been tied into the size of a subnet since CIDR was invented.
