There are several geolocation tools available for free on the Internet, but no one
should rely upon them alone because they may not be completely accurate.
HostlP.info uses two sources of information to generate its geolocation tool: people
identifying their city as associated with an IP address and automatic traceroutes.
Networldmap also uses information entered by people visiting their site and has
recently added links to its commercial site, Geobytes, which provides a more
detailed report on IP address geolocation. For more details on using these tools, go
to the section on Geolocating Internet Addresses.
5. What else can we learn?
Autonomous System Numbers (ASN) can help physically locate domain names and
IP addresses. ASNs are unique numbers (written AS1234) associated with
something called an Autonomous System (AS). An AS is an IP network with a
single, clear external routing policy, which is used to exchange routing information
between various Autonomous Systems. In short, each AS establishes a set of rules
for how Internet traffic can travel between and among IP networks around the globe.
In the case of avp.ru/kaspersky.com, the ASN is AS8342. Using the AS Whois
Lookup tool available at Eye-Net Consulting, we see that AS8342 belongs to RT-RU,
which is the Russian telecommunications giant, Rostelecom, one of the two principal
shareholders of RT-COMM.
