The present application is directed to systems and methods for associating a geographic location with an IP address. Generally, an IP address from which each of a plurality of users accesses a network is recorded. A geo tag is associated with each of the plurality of users and a subset of the plurality of users is identified, the subset including users associated with a first IP address. The subset of the plurality of users is clustered into a spatial cluster including users associated with geo tags located with a defined distance of a geo tag of at least one other user of the cluster. A geographic location associated with a geographic center of the cluster is then associated with the first IP address.
