Among other disclosed subject matter, a computer-implemented method includes receiving a first, a second and a third network address mapping. The method includes mapping each of the network addresses in the first, second and third network address mappings to respective first, second and third locations. The method includes determining, for each of the network addresses in the first, second and third network address mappings, location agreements. The method includes determining a first and second network address mapping agreement rate, a first and third network address mapping agreement rate, and a second and third network address mapping agreement rate, respectively based on location agreements determined for each of the network addresses. The method includes determining a confidence level associated with the first network address mapping based on the agreement rates.
