Hey Naman and all,

First of all thank you very much! Apologies for late reply. Couldn't come
only for two days.

okay. vov!! calm down. Nothing can happen without an IP address. Which is

Well theoretically what my professor said is IP addressing is done in
'networking layer' in OSI model. It is used for only communicating among
other networks. Thats why using IP address for masking so routing can be
managed easy. Otherwise each router may have to include large MAC address
table in each of them. But I'm working in a small LAN so I thought it's
better. (Is it true?)

For improving data transfer rate. Not only it makes more data can be
transferred but also reduce the processing (decoding). (Yeah I know its not
that much effective)

I have Zioproto in my g+. Hope others may be interested to comment on this
mail too. :-)

Thanks again for everyone. Waiting for more guidance.
Yours faithfully,
