There are mainly two type of Addresses:-

1.Physical Address( MAC address)

2.Logical Address ( IP address )

The physical address is also called the MAC address and it is generated by the manufacturer of

NIC(network interface card ).

The Media Access Control (MAC) address. MAC addresses are six bytes (48 bits) that

manufacturers of network adapters burn into their products to uniquely identify them.

Example:

01:02:31:a2:b3:cf

A network interface card (NIC) is a computer

circuit board or card that is installed in a

computer so that it can be connected to a

network.

Click Start then Run

Enter: cmd

Enter: ipconfig /all

The Physical Address is your MAC address; it

will look like 00-15-E9-2B-99-3C. You will have

a physical address for each network connection

that you have.

(PHYSICAL ADDRESS )

Internet Protocol Address (or IP Address) is a 32

bits unique address that computing devices use

to identify itself and communicate with other

devices in the Internet Protocol network

IP address uniquely identify all computers on the

public Internet.

It signifies the address of both the sender and

receiver of packets on a network.

Example: 172.16.254.1 (IPv4) 32 bits

2001:db8:0:1234:0:567:8:1 ( IPv6) 128 bits

Type of IP Address1. Static ip address: A static IP address is an IP

address that can be manually configured for a

device and it will never change

2. Dynamic ip address: A dynamic IP address is

an IP address assigned by a DHCP( Dynamic

Host Configuration Protocol) server which can be

change automatically any time.

Advantages:

Running Servers

computers using this type of address can host servers containing data that other computers access through the Internet.

Stability

Static IP addresses are also more stable for Internet use since they never change

Disadvantage:

Need Many Numbers of Addresses

One main disadvantage of static IP addresses is that each address, once assigned, is occupied by a single computer even when that computer is not in use.

Advantages:

Need less administration

It requires very less administration because all work is done by DHCP automatically

Save Time

In a large LAN network, dynamic IP helps you to save your time as you need not to configure hundreds of computers manually

Disadvantage: Can’t make server

The main disadvantage of dynamic IP is that it is not suited to web hosting. You would require static IP then.

Click Start then Run

Enter: cmd

Enter: ipconfig /all

The IPv4 is your IP address; it will look like198.165.25.12

We can also check IP is Dynamic or Static

If the line DHCP Enabled has a Yes beside it, you have a dynamic IP address if there is NO beside DHCP you have static IP Address
