subnetting for local networks

ok thank you but i have a comment, i feel this is usflul only for internet providers, because why an organisation want to make all its computers IP addresses public ?

and if i got a public ip address and subneted it will all ip addresses that will be generated from that will be public also ?

and about the ip address range i mentioned in the example how come its public i mean it can be local i can assign it in the range for local network when installing the dhcp server right ?

thank you, i will post these questions in a new related qestion do yu can gain more points :)

well, the reason for giving each computer a public IP address for security reasons, bandwidth also.
but it cost  a lot.
if you get a public ip address , you could subnet it to a rang of computers, which every PC would have  a private ip address.

For the private address, it would take the range that you give it.
you must differentiate between public and private ip address, when one of the local computers send packet to the Internet, then the source of that packet will be the public ip address.

hm...
I would suggest using private addresses where possible, even in DMZ and map appropriate services on the firewall to the real addresses.

thanks slinkygn
ok so what you mean by 192.168.0.0/16  what l16 means ?
also to subnet a network what setting i need to do to dhcp ? just the ip range and the mask ? no additional setting for server or client ?
CDR
the number of 1 in the subnet
so the subnet is 11111111.11111111.00000000.00000000 which is 255.255.0.0

you must use the public IP from the ISP with its subnet mask and DNS
client is configured  to get DHCP ip
