Regards to all,
Thanks for all your awnsers.
I was away for 3 days and so could not
respond
Many of the awnsers that I got all
pointed towards the same direction-HOW websites are
located not WHERE the location process is performed.

each ISP and each private network has some range of
network
numbers assigned to it. these ranges are consecutive
addresses,
for instance 129.240.0.0 through 128.240.255.255.
.......................................
WHO assigns these range of addresses to the ISP?

you probably want to take a look at
_DNS and Bind_, 4th edition, Paul Albitz & Criket Liu,
O'Reilly &
Associates, ISBN
0-596-00158-4
...............................................
The material was too technical for me to understand.
Give me some time and I will digest it.

Domain names (www.something.xyz) are resolved using a
network of DNS
(Domain
Name Service) servers. There are in fact a few central
servers to this
system, but they usually don't serve the crowds. This
is the job of
each
ISPs own DNS servers, wich are updated frequently with
new entries from
the
central DNSes.
.................................................
WHO owns these central DNSes?

Aronson, David
your computer first looks
in
the "DNS cache", which is where it temporarily stores
DNS "resolutions"
it
got before, recently. If it doesn't find it there, it
looks in a few
tables
where some resolutions are set up permanently. If
it's still not
found, it
goes to the IP address you configured as its "DNS
server". If THAT one
doesn't know, then it tells you where to look it up in
the official
records,
which is the main answer. It should know the IP
address of at least
one
system that is "authoritative" about all .com domains,
including
example.com. (And likewise one for each of the other
"official"
domains, or
at least where to find out about such official DNS
servers.)
...........................................
WHO owns this "authoritative" system

The link provided by Henry Bibb was interesting. The
material was too big to be read in one day. I will
give the feedback in a day or 2.
Thanks once again for the awnsers....Will be back
soon.
