1.What are the IP addresses assigned to the interfaces on your computer?

2. We have seen in this chapter that the network parts of IP addresses identify the owners of IP address blocks. Use the WHOIS search facility at the American Registry for Internet numbers (http://www.arin.net) to search the WHOIS database and identify the owner of the address block to which your IP address belongs. You can do this by visiting http://www.arin.net typing in your IP address into the search WHOIS field on the site press enter or click the button next to the search field. (Please see Figure 4.19 for reference.) Follow the link to the “related organization’s POC records” just below the table to gather information on the following fields associated with your IP address: a. OrgName b. NetRange c. NetType d. NameServer e. OrgTechName f. OrgTechPhone

3. Is the OrgName the same as your ISP’s name? (If not, we will explore the main reason for this in Chapter 7.) Ping the website of your university. Show the output. What is the average round-trip time? (If your university is locked down, i.e. does not respond to ping queries, try your ISP’s website.)

4. Ping the website of a university in a neighboring city or town. Show the output. What is the average round-trip time? (Again, if the website is locked down, try the website of a company in another state.)

5. Ping the website of a company, university, or organization located abroad. Show the output. What is the average round-trip time?

6. You wake up one day to find that you are unable to connect to the Internet from home. You make some calls to your friends and neighbors and find that they have no issues connecting to the Internet. You conclude that the fault is within your home. As seen in Figure 4.21, there are two networking components within your home—your computer and your home router. As seen in Figure 4.22, the IP address of the home router is the IP address of the default gateway in your ipconfig output, and home routers typically respond to ping requests. How can you use ping to determine whether the network connectivity problem is at the home router or at your computer?

Solution

1.

IP Addresses go to network interfaces, not to the computer itself. You don\'t jingle a computer, you ring a computer\'s network interface.

Even if you ping 127.0.0.1 , 127.0.0.1 is recognized as the loopback interface. So still that is notorious as an interface.

A computer could have a NIC with many ethernet sockets, many network interfaces and each one with a dissimilar IP Address

There aren\'t many examples of IP Addresses that do not belong to an interface.

For instance, the below are belongs to an interface of a computer:

iface eth0 inet static

    address 192.168.1.180

    netmask 255.255.255.0

    broadcast 192.168.1.255

    network 192.168.1.0

    gateway 192.168.1.1
