descr:          Internet service provider operations
remarks:        peering coordinators for AS3320: <peering@telekom.de>
remarks:        abuse reports should be sent to the contacts listed in the registry entries for the IP address of the offending host system
remarks:        We share the view that for many networks (including ours:-) only some abstraction of the actual routing policy should/can be published in the IRR. Right now we are abstracting to a very essential minimum.
remarks:        the most important and helpful use of the IRR is to publish what a network will announce to peers and upstream
remarks:        we encourage all our neighbors to define and maintain an AS-set to describe their announcements, and to register all the routes (and have their customers do so as well)
remarks:        we maintain a list of what our neighbors have told us about their announcements towards AS3320 - in terms of AS-set (preferred), AS number, route-set (and the IRR database used to publish)
remarks:        in fact we apply route filters based on this for all neighbors - as far as feasible
remarks:        for data published through the RIPE routing registry we generate filters automatically
remarks:        we consider the integration of RIR and routing registry data and the application of RPSS authorization a great feature of the RIPE routing registry
remarks:        customers are strongly encouraged to define and maintain an AS-set that we will include in the definition of AS3320:AS-DTAG (if we are told the name)
remarks:        this will be sufficient to have our peers accept the routes
remarks:        in any case peers - and any network in the Internet - is free to apply some selective policy (e.g. prefix length based)
remarks:        unfortunately some customers do not provide usable IRR data; we will NOT add to the uncontrolled garbage in the IRR by proxy registering in some database that requires no authorization
remarks:        we advise customers that routes without IRR registration and not covered by AS3320:AS-DTAG may receive less than full support by some of our peer networks and other parts of the Internet
remarks:        ============================================================== IPv6 we do/publish essentially the same like for IPv4
