Folks, A couple of weeks ago we published a new IETF I-D entitled "Security Implications of IPv6 on IPv4 networks". The I-D is available at: <http://tools.ietf.org/html/draft-gont-opsec-ipv6-implications-on-ipv4-nets> The Abstract of the I-D is: ---- cut here ---- This document discusses the security implications of native IPv6 support and IPv6 transition/co-existence technologies on "IPv4-only" networks, and describes possible mitigations for the aforementioned issues. ---- cut here ---- We're currently working on a revision of the document, so any comments will be really appreciated. Thanks! Best regards, -- Fernando Gont SI6 Networks e-mail: fgont@si6networks.com PGP Fingerprint: 6666 31C6 D484 63B2 8FB1 E3C4 AE25 0D55 1D4E 7492
