Data centers

Community-IX currently operates infrastructure at the following locations:

  • A36: Alboinkontor (Speedbone), Berlin: 1G/10G
  • L105: Lützowstr. (I/P/B/), Berlin: 1G/10G
  • N15: Nonnendammallee (NTT GDC), Berlin: 1G/10G
  • W19: Weismüllerstr. 19 (DE-CIX/Interxion), Frankfurt: 1G/10G
  • W23: Wilhelm-Fay-Str. 23 (MK Netzdienste), Frankfurt 1G/10G

Please contact us if you need cross connects to us in these data centers. In addition to peering, we can switch dedicated VLANs between individual communities, even across locations.


The following policies serve to ensure the security of the peering platform and must be observed at all times. Violations can result in port shutdown and exclusion from the peering LAN.

  • Only Ethertypes IPv4, IPv6 and ARP allowed.
  • MAC addresses are filtered per port.
  • Proxy ARP must be disabled.
  • The peering LAN prefix must not be announced via BGP.

Route Servers

Our route servers based on Bird are available redundantly. We recommend that all communities and sponsors set up BGP sessions to both route servers, as some IP-Transit sponsors only peer with the route servers and do not set up dedicated BGP sessions to individual communities. This also means the least effort for both sides.

  • ASN: 57555
  • Route Server 1: / 2001:7f8:a5::5:7555:1
  • Route Server 2: / 2001:7f8:a5::5:7555:2
  • BGP sessions are passive. The route servers do not establish a BGP session.
  • Prefixes of the peers are filtered based on the AS sets.
  • AS set: AS57555:AS-MEMBERS

Route Server Policy / BGP-Communities

Both RFC1997 Communities and Large BGP-Communities are supported. If one of the blackhole communities is added, the route will only be announced to peers where blackholing is also active. Regions that can currently be set are BER (100) and FRA (200).

BGP-Communities for Traffic-Engineering
