There is no good rule of thumb to determine the geolocation of Internet IP addresses. While some IP blocks tend to belong to certain countries, other IP blocks are distributed in an almost anarchic fashion. Moreover, the IP distribution is not static but in a continuous mutation with new additions, reallocations and deletions.
AWIPLOC allows you to resolve IPs to Country, City, Region and ISP by providing instant access to our 1100 MB online databases with more than 7.1 million IP ranges.
Our databases are fully indexed and the access is made through an industrial strength blazingly fast multithreaded ISAPI server supporting many hundreds of simultaneous connections. You will be surprised by the fastness of the responses.
You are not limited to request information about a single IP address at a time, you can request information about multiple IPs at the same time up to a maximum of 100 per batch. The response is sent to you in a tightly compressed format and the total query time, including
travel time, range from less than 1 second to just a few seconds in the worst scenario of the maximum batch size.
