The argument that we are running out of public ipv4 doesn't make sense to me. Consider %99 of nbn users are always on and therefore issued an ipv4 public address. Therefore having dynamically allocated ipv4 addresses does not allow them to make better use of the limited number they have been allocated assuming 99% of everyone who has nbn with tpg have there modem on and powered and therefore have a public ipv4 address. Please correct me if I am wrong. I am curious if any NBN customers are NAT'ed. I know I am not.
