# Historical List of RIS Routing Beacons

This page lists all beacons that were announced by RIS since 2002 and have since been disabled.

Note: Until February 1st, 2024, all IPv4 beacons were tagged with the RRC identifier as part of the BGP AGGREGATOR attribute. This encoding was done as follows:

  • AGGREGATOR IP ADDRESS: 10.x.y.z, where x, y and z form a 24-bit count of the number of seconds between the start of the month and the time of the announcement.
  • AGGREGATOR AS NUMBER: 64512 + n, where n is a 10-bit number encoded as
MSB                                   LSB
+---+---+---+---+---+---+---+---+---+---+
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
+---+---+---+---+---+---+---+---+---+---+
|    RRC ID     |    Sequence Number    |
+---+---+---+---+---+---+---+---+---+---+

Adding 64512 brings the resulting number into the private AS number range.
