Abstract:
Abuse response in a Carrier Grade NAT environment requires Service
Providers to be able to map a subscriber's inside address with the
address used on the public Internet. Unfortunately, many Carrier
Grade NAT abuse-response solutions require per-connection logging.
Research indicates that such logging is not scalable to many
residential broadband services. This document suggests a way to
manage Carrier Grade NAT translations in such a way as to
significantly reduce the amount of logging required while providing
traceability for abuse response. While the authors acknowledge that
IPv6 is a preferred solution, Carrier Grade NAT is a reality in many
networks, and is needed in situations where either customer equipment
or Internet content only supports IPv4; this approach should in no
way slow the deployment of IPv6.
