Traveling Through a Network (Ping/Traceroute)
I
used the ping command to test my connection to Google.com. Everything
went smoothly, 4 packets were sent, 4 were received, and there was 0%
packet loss. The response times were between 17ms and 21ms, which shows a
pretty fast and stable connection.
Then
I decided to ping two websites outside the U.S. to see how distance
would affect the results. I chose www.nic.ad.jp (based in Japan) and
www.abc.net.au (from Australia). Both pings were successful, with no
packet loss, but the response times were definitely higher—120ms–130ms
for Japan and around 190ms–200ms for Australia. That makes sense
considering how far those servers are from me.
Part 2: Traceroute Activity
Running tracert
to Google.com gave me a clear path through about 13 routers. The hop
times were all pretty quick most of them between 10–35ms and there was
one timeout.
The
traceroute to www.nic.ad.jp went through 17 hops, with longer response
times, some getting close to 220ms and 4 timeouts. When I ran it for
www.abc.net.au, it took 14 hops and 4 of them timed out or just didn’t
respond, which probably means those routers were blocking traceroute
responses or were overloaded.
Part 3: Traveling Through a Network Reflection
This
activity really helped me understand how information travels across
networks. Ping is a great way to quickly check if a website is reachable
and how long it takes for data to make a round trip. Traceroute is more
detailed it shows each stop along the way, like tracking a package
through every post office it visits before it gets to you.
When I
compared my results, I noticed a clear pattern: the farther away a
server is, the longer it takes for data to reach it. Google had the
fastest results since it's probably hosted closer and uses highly
optimized servers. Japan and Australia took longer, had more hops, and
showed how distance and routing affect performance.
Ping and
traceroute are also really useful for solving connection issues. If ping
doesn’t work or the times are high, it tells you something’s wrong.
Traceroute can help you see exactly where the problem is happening,
maybe it’s your ISP, or maybe it’s a router halfway around the world.
Timeouts
or errors can happen if a router is blocking ICMP traffic (which these
tools use) or if the router is down or just too busy to respond. I saw
that with the traceroute to Australia, where a couple of hops just
didn’t answer.
Overall, this was a cool hands-on way to actually
see how the internet works behind the scenes. It definitely made
networking feel more real and less abstract.
