I have an open peering policy, though be advised that AS208768 is currently used only for my personal traffic and to facilitate my (physics, not network) research.
The relevant AS-SET is AS208768:AS-MAIN (though it contains only AS208768). I currently peer only on IPv6, and suggest a max prefix limit of 20. I am currenttly located on FogIXP and LocIX Frankfurt.
I reserve the right to terminate peering, or change this policy, at any time, without notice, and to decline peering requests for any reason.
