Why IP Database Lookup Results Disagree
Published Updated
Two IP databases can return different cities, network types, or risk results for the same address. The difference usually comes from their evidence, address granularity, and update timing.
Location results depend on the field and range detail
Registered in shows where the address space is registered. Used in shows where a source currently locates the network's use.
Granularity matters too. One source may have a record for a broad range while another recognizes a more specific prefix. The same ASN can serve several cities and products, so a more specific record can lead to a different city.
Residential and Datacenter depend on range use
The same operator can use different address ranges for access, business, mobile, or datacenter services.
Results change as networks and databases update
Address space can move, routes can change, and carriers can reassign pools. When sources reflect those changes at different times, their results differ.
Compare results within the same field
Usage Type describes the network's role. Company Type describes the operating organization. Risk results describe signals such as Proxy, Hosting, and Abuse.
