Broadcast IP
Broadcast IP: APNIC allocated this block to Netherlands (NL), but the address is geolocated in Czechia (CZ). The block is announced outside the country it was registered in — typical for cloud, hosting and VPN providers that move address space between locations. Strict websites treat this as a weaker "local" signal than a native address.
