DNS provider

arcor-ip.de
Jan – Feb 2009

Solid bar: the stretch we observed that name. Dot: a single sighting. Dotted line: no record between sightings of the same name. Nothing is drawn between different names.

DNS provider, WHOIS snapshots: 16 WHOIS/RDAP snapshots that listed nameservers, 2009-01-06 to 2009-02-15 (who.is archive). Both sources feed one row per provider (hover a bar to see which); a change is placed between the nearest observations on either side, and where the two sources disagree, both are listed under What changed.
