Please add the abilty to geocode an IP address. This should be an offline dataset at the country level in the data and maps DVD. Additionally, at the city or lower level, this should be a service on ArcGIS online.
The need to locate the closest lat long of an IP address, and then create a usable featureclass, is a needed feature. This is increasingly important due to emerging areas of geospatial analysis, such as cyber security. An IP address database is not something a user could even begin to create on their own, and thus would be a valuable additional service to have within ArcGIS online. It would need to be a service since it would need to be maintained and updated.
Also have a geoenrichment capability to add the Internet provider (ISP) attributes.
