Data Retention More Complicated, Expensive Than Previously Understood | Center for Democracy & Technology
CDT has concluded that changes in the Internet addressing practices
of ISPs and mobile carriers make data retention far more complicated and
much more expensive than previously understood, while at the same time
reducing the reliability of IP addresses in identifying individual
users. We've issued a memo detailing this new perspective on the data
retention mandate.The problem is this: The IP addresses
associated with communications traversing the Internet no longer
uniquely identify end-user devices. Because of the shortage of IP
addresses, Internet access providers are beginning to use a technique
called Network Address Translation to share addresses among multiple
users.
