Dear Subhranshu Ganguly,

Greeting. To assign a network device an IP either done manually or by enabling DHCP server (service) on the desired device.

1. Manually/Automatically for PC's:1.a for computer open network and sharing center select TCP/IP v4 protocol then properties fill the boxes IP, DHCP,... or select APIPA option.

1.b Or you can enable or disable DHCP service from control panel----admin tools--- services select DHCP client

2. Manually/Automatically for Router:

Access configuration page of your router (..X.X) you can check your router page online.

select setup service and go for DHCPSame can be done for server, printer, IP camera

.-----------------------------------------------Finale Note:

DHCP(Dynamic Host Configuration Protocol): is not only responsible of assigning IP's it also DNS, subnets and subnet masks.

It's called DHCP (Dynamic Host Control Protocol)

You  can configure DHCP.

Its possible By two way

DHCP on your Router:

Router(config)# ip dhcp pool dhcpool //dhcpool

Router(dhcp-config)# network1.1.1.0

Router(dhcp-config)# default-router1.1.1.254 //"your network gateway"

or

Enabel DHCP Role on Windows Server.

auto ip addressing is beeing handle by a protocol know as Dynamic Host Configuration Protocol. tjis protocol is responsible for giving out ip addresses base on the range you have configured .

i can write a full book on this if you need futher help massage me 

Configure a DHCP Server or enable DHCP on your router. Then configure IP Pool. in the IP pool you can  exempt  some IPs from being assigned. e.g network and broadcast address, Server adresses or some crucial service IP addresses.
