1. Network Tools - Using Whois, Tracert, Ping
TCP/IP comes with an array of simple tools to monitor networks. Usually you would access these via a command line (prompt), but because you cannot do so here I have provided links below to websites which offer these tools through a web interface. Here is a list of important tools for managing IP networks. Try out the domain dossier, ping, traceroute and analyzepath to see what they offer and then leave a comment on your findings:
- Investigate domains and IP addresses. Get registrant information, DNS records, and more.
- Domain Check
- See if a domain is available.
- Email Dossier
- Validate and investigate email addresses.
- Browser Mirror
- See what your browser reveals.
- Ping
- See if a host is reachable.
- Traceroute
- Trace the network path from this server to another.
- NsLookup
- Look up various domain resource records with this version of the classic NsLookup utility.
- AutoWhois
- Get Whois records automatically for domains worldwide.
- TcpQuery
- Grab a web page, look up a domain, and more.
- AnalyzePath
- Do a simple, graphical traceroute.
Here are a number of links to sites which offer these services:
Secondary/Curriculum/Computing/Software/Visualroute
Other popular tools include port scanners - these are used by hackers to identify open ports in a network which they can utilise.
How Traceroute Works?
Traceroute is used to trace the path that datagram traverses to reach its destination. It gives one path from point of origin of data packet to its final destination, there is no assurance that data will travel same path each time. Mostly all Unix like operating systems provide traceroute tool, Tracepath is available in latest Linux flavors and Microsoft OS provides tracert tool. Traceroute command uses ICMP utility to trace the location of each router. TTL value represents the number of nodes (routers or gateways) a data packet can travel.

this is really cool and super fun!!! i just stalked my favorite band and my favorite author
It's interesting that we can do all of that with those websites... but all of that information means absolutely nothing to someone like me. Still pretty cool, though.
lolfail CBS blocked themselves
I think its cool you can follow the address but, I can't figure out any of the info.
I found it really funny that someone thought that the more space they had on their hard drives, the more heavier they were haha. Sometimes I wonder if people post that sort of stuff as a joke or if they are being serious.
when do we learn to hack?
personally i believe that the comics about facebook were 100% accurate, all we hear is complain and every once in a while a good status comes along besides that all i see everyday is "i am bored" to what i sometiems replay "your status made my day"!!
It looks really useful to a hacker and all, but I'm not a hacker so that stuff is just really coo looking words to me. Never thought that there were websites for this stuff.
