A new Request for Comments is now available in online RFC libraries. RFC 7768 Title: Port Management to Reduce Logging in Large-Scale NATs Author: T. Tsou, W. Li, T. Taylor, J. Huang Status: Informational Stream: Independent Date: January 2016 Mailbox: tina.tsou@philips.com, mweiboli@gmail.com, tom.taylor.stds@gmail.com, james.huang@huawei.com Pages: 11 Characters: 23442 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-tsou-behave-natx4-log-reduction-06.txt URL: https://www.rfc-editor.org/info/rfc7768 DOI: http://dx.doi.org/10.17487/RFC7768 Various IPv6 transition strategies require the introduction of large- scale NATs (e.g., AFTR and NAT64) to share the limited supply of IPv4 addresses available in the network until transition is complete. There has recently been debate over how to manage the sharing of ports between different subscribers sharing the same IPv4 address. One factor in the discussion is the operational requirement to log the assignment of transport addresses to subscribers. It has been argued that dynamic assignment of individual ports between subscribers requires the generation of an excessive volume of logs. This document suggests a way to achieve dynamic port sharing while keeping log volumes low. INFORMATIONAL: This memo provides information for the Internet community.
