This is the trace route output of 61.1.196.1 using the website whatismyipaddress.com.

 

The visual tracert 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. Concerning trace routes The IP packet is having a field called "time to live(TTL)".Normally its intial value is 30. In case of windows, it may even be 128.. Every time a host forwards a packet, it decrements the TTL value of the packet by one. If the TTL value of a packet is zero and it has yet to reach its destination, the packet is discarded and the host will send a response back to the sender notifying them that the destination was not reached. The main purpose of TTL is to prevent packets from endlessly looping around the Internet, never finding their destination. A “trace route” works by increasing the TTL value of each successive packet sent. The first packet is sent with a TTL value of one (implying that it will make a single hop). The next packet has a TTL value of two, and so on. By doing so, a destination unreachable response packet is elicited from each hop. These returning packets are used to produce a list of hosts that the packets have traversed en route to the destination.
