1.Find your computer’s IP address

Type in ipconfig and press enter

What does that mean?

It stands for “Internet Protocol Configuration”, it shows that all current network configuration values.

When I pressed enter I’ve got these.

C:\>ipconfig

Windows IP Configuration

Ethernet adapter Local Area Connection 6:

Connection-specific DNS Suffix . : itd.uts.edu.au,uts.edu.au

IP Address. . . . . . . . . . . . : 138.25.244.31

Subnet Mask . . . . . . . . . . . : 255.255.255.0

Default Gateway . . . . . . . . . : 138.25.244.1

It shows DNS, IP address, Subnet Mask and Default Gateway.

I guess we are in LAN, it shows only this much information.

What is an IP address?

IP address stands for “Internet protocol” address, it is a numerical identification which can communicate each computers (nodes).

2. Find the IP address of the UTS web server

Type in nslookup www.uts.edu.au and press enter

How is it related to the IP address of your computer?

nslookup stands for “Name Server Lookup”

C:\>nslookup www.uts.edu.au

Server: ns.uts.edu.au

Address: 138.25.16.1

Name: manifera.itd.uts.edu.au

Address: 138.25.16.22

Aliases: www.uts.edu.au

This computers and these servers IP addresses are under 138.25.*.* range. I guess this computer is belonging to 138.25.*.* which can not be seen outside. It is something like you can use this range of IP address privately.

3. Traceroute:

type in: tracert www.google.com

What does that show you?

When I typed tracert and pressed enter I’ve got these results.

C:\>tracert www.google.com

Tracing route to www.l.google.com [209.85.171.99]

over a maximum of 30 hops:

1 210 ms 15 ms 15 ms gh-117-c1924-2.sw.uts.edu.au [138.25.244.3]

2 3 ms <1 ms <1 ms 172.16.104.1

3 3 ms 1 ms <1 ms 172.16.0.1

4 1 ms 1 ms 1 ms 172.16.30.254

5 <1 ms <1 ms <1 ms GW-L2-5052.uts.edu.au [138.25.252.38]

6 * * * Request timed out.

.

.

.

30 * * * Request timed out.

Trace complete.

Type in: tracert linus.it.uts.edu.au and press enter

C:\>tracert linus.it.uts.edu.au

Tracing route to linus.it.uts.edu.au [138.25.8.1]

over a maximum of 30 hops:

1 15 ms 15 ms 17 ms gh-117-c1924-2.sw.uts.edu.au [138.25.244.3]

2 4 ms <1 ms <1 ms 172.16.104.1

3 <1 ms <1 ms <1 ms 172.16.210.2

4 1 ms <1 ms <1 ms linus.it.uts.edu.au [138.25.8.1]

Trace complete.

- What happens this time? Why might the two be different?

Tracert is a tool that can be used to determinate each router which this packet has to jump on it. So google needs a lot of hops but uts’s has to jump only four jumps.

4. Ping

type in: ping a space, then the IP address of the UTS web server

What happens?

C:\>ping 138.25.244.31

Pinging 138.25.244.31 with 32 bytes of data:

Reply from 138.25.244.31: bytes=32 time<1ms TTL=128

Reply from 138.25.244.31: bytes=32 time<1ms TTL=128

Reply from 138.25.244.31: bytes=32 time<1ms TTL=128

Reply from 138.25.244.31: bytes=32 time<1ms TTL=128

Ping statistics for 138.25.244.31:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 0ms, Maximum = 0ms, Average = 0ms

What does that mean?

Ping is a network tool that can be used for that particular computer is reachable or not.

It sends a packets and determine how long it takes to return and whether it has been lost or not.

5. Registering a domain name

in a web browser go to www.register.com type your family name into the Search for a domain name box choose .com as the domain type then click

go if that domain name is available try a more obvious one like google.com

click on the View Whois link to see who has registered it

I’ve got this result when I checked my sir name.
