Dear Arun Khan,
Thanks for providing me the valuable information. I am sorry, I
don't have any networking knowledge.
Regards,
S.Vellingiri.

I don't understand this at all. These are not LAN(RFC1918) IPs.
LAN IPs are private IPs that are either 192.168/16 or 172.16/12 or 10/8.
Not necessarily. Agree with your comment in today's time frame but
one can use "Public IPs" on the LAN. Although it would be waste of
valuable resource. Companies had to buy block of IPs pre RFC 1918.
I can see the six LAN IPs you mention. But they cannot be used since
they lie on a different network. Look at this.
Not true -- OP needs to install a router with 2 NICs, one for the LAN
115.248.77.48/29 subnet and one for the WAN subnet 115.248.76.24/30.
The router can be a Linux box or an embedded appliance. The ISP, in
it's cloud, has routing entries to subnet 115.248.77.48/29 behind gw
115.248.76.25 or something similar. It does not matter as long
packets leave and arrive w/o the OP having to go through the hoop.
IMHO, the OP is unable to articulate what he wants to do with the
bunch of IPs that he has got and needs to consult a professional
network engineer. IMO, network setup should be presented in a visual
form rather than in words but unfortunately very few people do.
I am hazarding a guess as to what his company wants to do. They
probably want to run a few servers with the public IPs in the
115.248.77.48/29 subnet, with one IP to be used by the GW to it's
corporate LAN with RFC 1918 IP numbering scheme behind this gateway
like so:
ISP
|
|<< 115.248.76.24/30
|
------------------- OP's "public" router
|
|<< 115.248.77.48/29
========================
| A |B | GW | C |D
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(GW Router with RFC 1918 LAN)
