This lookup page allows you to check what IP address a given .dy.fi name was pointing to at a given time. It currently covers the last three months worth of changes.

Enter the part of the hostname that appears before the .dy.fi domain suffix only.

Please note that the exact time you are interested in must be entered in UTC (or GMT) and must be entered the way we do in Finland, ie. "day.month.year". For example, 1.10.1977 or 31.12.2003.

Wildcard lookups of any kind are not permitted. You must enter an exact, valid hostname.
