Folks,
We have published a new IETF I-D entitled "Current issues with DNS
Configuration Options for SLAAC", about existing problems with the DNS
configuration options used with SLAAC.
The I-D is available at:
<http://tools.ietf.org/id/draft-gont-6man-slaac-dns-config-issues-00.txt>.
Abstract:
---- cut here ----
RFC 6106 specifies two Neighbor Discovery options that can be
included in Router Advertisement messages to convey information about
DNS recursive servers and DNS Search Lists. Small lifetime values
for the aforementioned options have been found to cause
interoperability problems in those network scenarios in which these
options are used to convey DNS-related information. This document
analyzes the aforementioned problem, and formally updates RFC 6106
such that these issues are mitigated.
---- cut here ----
This version of the I-D discusses different *alternative* mitigations
for the forementioned problem. Your input will be very appreciated.
Thanks!
Best regards,
