RFC 8981
Title: Temporary Address Extensions for Stateless
Address Autoconfiguration in IPv6
Author: F. Gont,
S. Krishnan,
T. Narten,
R. Draves
Status: Standards Track
Stream: IETF
Date: February 2021
Mailbox: fgont@si6networks.com,

Pages: 20
Obsoletes: RFC 4941
I-D Tag: draft-ietf-6man-rfc4941bis-12.txt
URL: https://www.rfc-editor.org/info/rfc8981
DOI: 10.17487/RFC8981
This document describes an extension to IPv6 Stateless Address
Autoconfiguration that causes hosts to generate temporary addresses
with randomized interface identifiers for each prefix advertised with
autoconfiguration enabled. Changing addresses over time limits the
window of time during which eavesdroppers and other information
collectors may trivially perform address-based network-activity
correlation when the same address is employed for multiple
transactions by the same host. Additionally, it reduces the window of
exposure of a host as being accessible via an address that becomes
revealed as a result of active communication. This document obsoletes
RFC 4941.
This document is a product of the IPv6 Maintenance Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
This announcement is sent to the IETF-Announce and rfc-dist lists.
