. IP addresses assigned to device can be static or dynamic.
. Static IP address remains constant and it is assigned by ISP.
. Dynamic IP address keeps on changing and is assigned by ISP using DHCP.
DHCP Server:
. Stands for Dynamic Host Configuration Protocol.
. It assigns IP Address to devices in the network automatically.
. Present in the router which is inbuilt.
. Whenever DHCP clients (any device in network) request for IP Address, DHCP sends free IP Address to the requested device.
. Now the device can make use of that IP Address to access other devices and internet.
. It is not fixed, IP address may change dynamically.
DHCP Leasing Time:
. DHCP leases a unique IP address to each device in the network for a certain period of time called 'Lease Time'.
. Whenever lease time expires, assigned IP Address goes away.
. Again the process of DHCP Discover to DHC Ack goes on to assign a new IP address.
. Average lease time of an IP Address is 8 days.
. Whenever lease time expires, assigned IP Address goes away.
. Again the process of DHCP Discover to DHC Ack goes on to assign a new IP address.
. Average lease time of an IP Address is 8 days.
Static IP Address:
. Permanent number assigned to computer by Internet Service Provider.
. It is usually assigned to server hosting websites, data base, gaming, Voice over IP services etc.
. Manually configured to a device like tablet, router, laptops, desktops etc.
. Using Static IP means you can always access that computer with same address.
How to know whether your IP is Static or Dynamic?
. Type in 'ipconfig/all' in command prompt.
. See whether DHCP enabled is 'Yes' or 'No'.
. If it is Yes, then IP is Dynamic.
