About the author

Author image
Emile Aben Based in Amsterdam, NL

I'm a system architect/research coordinator at the RIPE NCC, where I work in the science group. I'm a chemist by training, but have been working since 1998 on Internet related things, as a sysadmin, security consultant, web developer and researcher. I am interested in technology changes (like IPv6 deployment), Internet measurement, data analysis, data visualisation, sustainability and security. I'd like to bring research and operations closer together, ie. do research that is operationally relevant. When I'm not working I like to make music (electric guitar, bass and drums), do sports (swimming, (inline) skating, bouldering, soccer), and try to be a good parent.

This is a nice dataset, thanks for making it available.<br />I noticed (taking the 20100811 archive) that in the &quot;arin&quot; subdirectory, there are both the unpacked files and two versions of sub-archives, ARIN.in-addr.arpa.tar and ARIN.in-addr.arpa.tar.gz. I verified that these are completely redundant and can be removed with no loss of information. That would reduce the size of the entire archive significantly:<br /><br />-rw-r--r-- 1 leinen wheel 75469506 11 Aug 18:37 in-addr.arpa-20100811-less-redundancy.tar.bz2<br />-rw-r--r-- 1 leinen wheel 192364964 11 Aug 08:41 in-addr.arpa-20100811.tar.bz2<br />

Nice resource, but I am afraid that something is missing, for example (AFAIK) RIPE/66.212.in-addr.arpa Is it possibile to have a check ?
