With IPv4 depletion Carrier Grade NAT (CGN) has gained a wider adoption, even though it has many issues. 

A comprehensive report by UK’s Ofcom (the government Internet regulator) has just been released, on the impact of CGN. More at http://stakeholders.ofcom.org.uk/binaries/research/technology-research/2013/cgnat.pdf

One of the author’s of the report, Dr. David Holder states; “This report is the most comprehensive analysis of the implications of Carrier Grade NAT (CGN) deployment ever carried out. The report demonstrates that CGN deployment has the potential to have a negative impact on a surprisingly widespread and disparate set of groups, consisting of users, service providers, law-enforcement and policy makers.”

With IPv4 depletion, matters will get worse until content and access move to native IPv6.
