This place has some very useful tools. Here's a brief summary of what they have to offer:

Open Port Finder - The port forwarding tester is a utility used to identify your external IP address and detect open ports on your connection. This tool is useful for finding out if your port forwarding is setup correctly or if your server applications are being blocked by a firewall.

Network Location Tool - The network location tool is a utility that approximates and displays the geophysical location of your network address on a Google Map. Currently, geolocation information is available from two sources, MaxMind and Hostip.info. The location database provided by MaxMind is 98% accurate on a country level and 70% accurate on a city level for the US within a 25 mile radius. Accuracy information is not available for Hostip.info; however, the Hostip database is open for user input so it is continually becoming more precise.

Visual Trace Route Tool - The visual trace route tool displays the path Internet packets traverse to reach a specified destination. The tool works by identifying the IP addresses of each hop along the way to the destination network address. The estimated geophysical location of each hop is identified using MaxMind's GeoIP database. After all of the hops locations' are identified, the path to the destination is plotted on a Google Map.

Phone Number Geolocator - The phone number geolocator allows you to quickly find the geographical area that a phone number originates from. Locations are identified by matching the area code (NPA) and prefix (NXX) of a phone number to a latitude/longitude coordinate. This tool currently supports most phone numbers within the United States. The database is a little dated, so information such as whether the number is a landline or wireless may be inaccurate.

Reverse IP Domain Check - A reverse IP domain check takes the domain name or IP address of a web server and searches for other sites known to be hosted on that same web server.
