Officers
5
The Aufsichtsratsmitglied (board member) of IONOS SE currently on record is Hüseyin Dogan; five officers are currently on record for IONOS SE, filed with Handelsregister (Commercial Register).

The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
IONOS SE sits 3 levels below its ultimate parent, United Internet AG, registered in Germany. 16 subsidiaries are recorded beneath it, across 9 jurisdictions. The full chain up to United Internet AG is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by IONOS SE's own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 16 subsidiaries span Germany, Poland, Philippines, United States, France, Spain, and 3 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Seven of the 16 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
