remarks:        
remarks:        Every 10' the prefix 2a0d:3dc1:XXXX::/48 is advertised. The
remarks:        XXXX is the number of 10' periods since the beginning of the
remarks:        year. So Jan 1 00:00 is :0000:, Jan 1 00:10 is :0001:, etc.
remarks:        Notice that it starts from 0 and not 1, as it should ;)
remarks:        
remarks:        Only one /48 should be available at any single time, which
remarks:        means that they should only be visible for 10' in the global
remarks:        RIB per year.
remarks:        
remarks:        Why? We are conducting research on BGP Stuck Routes to better
remarks:        understand how they happen, when, which equipment is more
remarks:        buggy, etc. We also want to understand them better. As this is
remarks:        a beacon, anyone can study the results using RIPE RIS, or any
remarks:        other source like RouteViews. Feel free to take a look and let
remarks:        everyone know if something interesting ever comes up!

remarks:        
remarks:        We are also studying the propagation of BGP Communities with
remarks:        this beacon, to minimize the count of BGP UPDATEs generated.
remarks:        At origin, all prefixes are tagged with the following values:
