SixXSSixXS accommodates an extendible whitelabeltunnelbroker to assist LIRs in having a rapid IPv6deployment in their organisation by providing a nativeand tunneled IPv6 broker, giving IPv6 access to theirclients even though intermediate hardware doesn’tsupport IPv4. Each PoP serves users based on thepolicies defined by the owner of the PoP.
More participating LIRs always welcome.
See http://www.sixxs.net for more information

European PoPs
17 PoPs in Europe
PoPs are named according to UN/LOCODE in the format of a two letter country code followed by a three letter city code and a two digit sequence number.

United States PoPsSince 14th of October, two PoPs in the USA (Chicago + Atlanta). Another 5 spread out over the USA will be deployed during the coming months.
OCCAID (http://www.occaid.org), who are running a public network for experimentation such as free (as in beer) IPv6 transit and a lot more is providing these.

More specific 6to4 prefixes6to4 is one of the several IPv4 to IPv6 transition methods. Section 5.2.3 of RFC3056 explictelyrestricts the propagation of more specifics than 2002::/16 to prevent polution of the IPv6 routing table by elements of the IPv4 routing table.

Long ASPath / GhostsPrefixes having a steady ASPath length ofover 12 ASN's will quite probably mean thatit concerns a so called Ghost Route.

• Filtering on maximum of /48• Many filter on /32's
• Announcing a more specific usually leads to long AS paths or ones over Korea/Japan
