I'd like to get as much information out of whois as possible, without
breaking the RIPE policies. Downloading the dump via FTP is an option,
yes, but as I wrote I'd prefer to avoid it. The main reasons for this
are that a) parsing this database is not very convenient and b) I'd need
to synchronize also with the other RIRs.
