Should ris IGNORE default routes?

RISwhois is a whois interface to the RIS data, intended to provide
a quick look at the collected BGP data. Format is compatible with routing
registries so folk who have tools build on whois queries to IRR, can switch
to RIS transparently. Useful for IP->AS mappings, but also for a first peek at
BGP tables before diving deeper with other RIS tools (looking glass, prefix
query etc.)

As for the question:


>> Are there any good reasons to keep riswhois reporting default routes?


I think riswhois server should not do any filtering on the RIS data
If someone feeds RIS a default route, it should pop up in the
RRC looking glass, the RIS database and RISwhois. It's up to the 
application to use it or ignore it.

If you don't want the currently present default route to appear
in ever riswhois query, use the -M flag:

	whois -h riswhois.ripe.net -M <ip-number>

will only return you the longest matching prefix.
