Simply network stuff. Online Traceroute, Whois, and a simple Dig DNS lookup. Tools that will blow your mind.... or maybe just help with troubleshooting and network recon.
This page has an online Traceroute that will test the hops in a network path. It takes the
mtr traceroute results, parses them, and plots the results on a Google Map. Starting from the traceroute-online.com server this test will show response times for each responding hop in the path. Non-responding hops will not be listed. Please note that geolocation is not an exact science and discrepancies may be found on occasion in the mapped results.
Tracepath, Tracert, tcptraceroute, traceroute and mtr are all similar tools that test the network path using either UDP, ping or tcp. See the wikipedia article for more details on the technical side of traceroute and the tools that we run. The Nmap port scanner has a traceroute function, try it online at HackerTarget.com
mtr is a diagnostic tool that combines
ping to perform a detailed analysis of a network path. The tool will ping each of the hops in the path a numebr of times to get an accurate measure of the stability and response times of each hop in the traceroute.
The protocol known as
whois allows an IP address or a domain name to be queried to determine the owner of that domain name or IP address netblock. Finding the owner of an IP address or domain name is common practice among security analysts and systems administrators who regularly track down abusive systems, spammers or identifying the owners of hacked systems.
dig tool is a primarly Linux based tools that is a more feature packed version of the common
nslookup command available on Windows and other operating systems. It allows a user to query DNS servers to find DNS related information. Common uses are determing the IP address associated with a domain record or to find the MX server for a domain.
