[afnog] AS# to IP range

[Jens Kuehlers]

Hi Mihamina,
since Google uses RADB it might be easy enough to get the prefixes with
something like this:
whois -h whois.radb.net -i origin AS15169 | grep route

You might filter out most of the /23s and /24s as they are just more
specifics of others.
The bigger routes should not change that often.
