A new Request for Comments is now available in online RFC libraries. RFC 3964 Title: Security Considerations for 6to4 Author(s): P. Savola, C. Patel Status: Informational Date: December 2004 Mailbox: psavola@funet.fi, chirayu@chirayu.org Pages: 41 Characters: 83360 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-v6ops-6to4-security-04.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc3964.txt The IPv6 interim mechanism 6to4 (RFC3056) uses automatic IPv6-over-IPv4 tunneling to interconnect IPv6 networks. The architecture includes 6to4 routers and 6to4 relay routers, which accept and decapsulate IPv4 protocol-41 ("IPv6-in-IPv4") traffic from any node in the IPv4 internet. This characteristic enables a number of security threats, mainly Denial of Service. It also makes it easier for nodes to spoof IPv6 addresses. This document discusses these issues in more detail and suggests enhancements to alleviate the problems. This document is a product of the IPv6 Operations Working Group of the IETF. This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited.
