Possibly related to this organisation

what's this?
Same operating domain tmcz.cz
Separately-registered clusters whose addresses resolve (reverse DNS) under the same domain as this one — strong evidence they are the same organisation, even where the names differ. Namesakes on other domains are excluded.
Same name family
Separately-registered clusters whose names share “T Mobile Czech Republic” — often per-country or per-system registrations of the same brand, occasionally a different organisation sharing the name. Not counted in this organisation's own footprint.
Sub-allocations under carriers
IP blocks an ISP reassigned to a similarly-named customer — decoded from the ISP's own naming convention, not a direct registration.
