The additional public ip addresses are for other servers, you may run and provide services to the internet and are static ip addresses.
E.g.:
You may run a public email server, that consumes one public ip address.
On another server you are running a web server, that should be accessable from the internet and therefore needs another public ip address.
In addition, you may run a database server, vpn server, own public DNS server a.s.o., which all must be accessable from the internet and therefore, you need public ip addresses.

But if you only need the internet line to surf the net, you only need one public ip address and this one ip address must not necessarily be a static ip address.

and if i have a 4mbps leased line 1:1 connection, and if i have around 200 PCs in my local company network, does it mean that each of the 200 comps get individual 4mbps net connection? or is the 1:1 applicable at the ISP side only, up-till the router/modem..??

and thanks for the replies again...much appreciated..

You only need one wan ip. You put a router in to provide 1:many nat translation so you can have 200 private ip addresses provided by the router.

You have better security and you control your private ip not the ISP.

You do not need the other ip addresses unless you plan on web hosting.

your line that your ISP gave you is 4 mbps that all systems on your network must share.

doesn't work that way Ananddhouni so no you will not get 4mbps at each pc. This is shared bandwidth.

If every computer would download a big file at the same time, you will get a theoretical speed of:your line speed devided by the amount of computers, that are downloading.
