IP address is address of the system in the Network.
Port is address of the service within the System.
So IP address + Port defines address of the particular service on the particular system.

IP address is use to identify a host or a group of hosts in a network
while port number is used to identify a particular service running in a host

Think about how many application layer protocols exist (HTTP, FTP, DNS, SSH, etc). Now think about how many task/process/programs exist within your device trying to communicate over the internet. Would it be possible just one address, the IP address, to be able to handle all these different assignments and types of protocols alone? The answer is no.
The IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. The port number is used so the data is directed to the correct location within this device.
The IP and the port number form the structure IP:port number, 192. 168. 1. 1:8080 for example, and the port number can hold 65536 numbers, with the following division:
0 to 1023 – Well known port numbers. Only special companies like Apple QuickTime, MSN, SQL Services, Gopher Services and other prominent services have these port numbers.
1024 to 49151 – Registered ports; meaning they can be registered to specific protocols by software corporations.
49152 to 65536 – Dynamic or private ports; meaning that they can be used by just about anybody.

Port number is used to identify an application/services which you want to talk to on your system. Some predefined ports like 80 = HTTP server, 23 = Telnet.
You identify a host uniquely (globally) by its IP address. So if I ever wanted to access your laptop via telnet then I’d use the IP address given to you by your ISP and the port 23

A MAC address is a layer-2 address. It is used by some layer-2 protocols, e. g. ethernet and Wi-Fi. There are 48-bit and 64-bit MAC addresses. Some layer-2 protocols use different addressing.
An IP address is the address of the layer-3 IP protocol. Different layer-3 protocols use different addressing, e. IPv4, IPX, and IPv6 each have different addressing.
A port number is a layer-4 address used by some layer-4 protocols, e. TCP and UDP. Some layer-4 protocols use different addressing, or none at all.
TCP example: RFC 793, TRANSMISSION CONTROL PROTOCOL
Multiplexing:
To allow for many processes within a single Host to use TCP
communication facilities simultaneously, the TCP provides a set of
addresses or ports within each host. Concatenated with the network
and host addresses from the internet communication layer, this forms a
socket. A pair of sockets uniquely identifies each connection. That
is, a socket may be simultaneously used in multiple connections.

Simply:
A socket is like a telephone (i. e. end to end device for communication)
IP is like your telephone number (i. address of your socket)
Port is like the person you want to talk to (i. the service you want to order from that address)
In networking, generally a socket is (IP+Port)

IP address: Ip address is a address of your system, it assign when your system connects to are two types of ip address available here among first one is dynamic which invokes at your system in online. Second one is static, which assign when your system get in offline.
port address Port address is an Id of server such as your using apache server that get port number default 8080 is id of apache server, If you can change server port number.

IP address is your system domain name or socket address of specific system like 192. 0. 1
but the port number is the number of specific location or folder where to you want to write your file or any file transfer like: 3308

The IP address of your computer (host) is the mix of the network ID of the ISP/any other provider (uniquely provided by the ICANN group) and the host name (provided by the Network administrator). The Network ID is unique for all the network and among two networks, we can have same host names but on the same network, the host names can not be the same. So, this is how the host can be identified on the network and data can be transferred. But on the same host multiple applications will be running and once the data reach to the host, we need an identifier to recognize which application data is this TCP Segment/UDP datagram.
The Port number is 16 bits (possibly 65K application can run) and assigned by the Network operating system when the application process creates the sockets. On the Server side, the port numbers are well defined numbers (HTTP- Port #80, SMTP- Port#25). The port number is transport layer addressing (L4) and goes in the header of TCP/UDP.

How to Find an IP Address and Port Number – Small Business …
The internet relies on a system of addresses that treats every computer, tablet and smartphone as a distinct device, allowing all of them to communicate with each other. Because many kinds of devices are involved, made by different manufacturers and running different software, the exact steps to finding an IP address and port information depends on the device you have. In general, you can find the address in the settings app, usually under Wi-Fi or network information. Define the IP Address A computer data network assigns a number called an Internet Protocol (IP) address to every computer and device connected to it. For example, your company’s Wi-Fi network might host many devices – smartphones, wireless printers and laptops. Each has an IP address, which works like the street address of a house or business. For example, when you print an invoice from a laptop, the network routes the data from the laptop to the printer using its IP addresses. IP addresses have two main formats: four decimal numbers each up to three digits long, separated by dots, or eight hexadecimal (base-16) numbers separated by colons. An IP address might look like “192. 168. 1. 67” or “2600:1700:7170:fb10:93:ac4c:810e:6785. ” Define the Port Address Every computer and mobile device runs many different internet-based apps, including email, web browsers and cloud storage drives. Each of these applications has one or more network “ports” assigned to it; for example, web browsers use port 80 and email programs use port 25. The port number is “tacked on” to the end of the IP address, for example, “192. 67:80” shows both the IP address and port number. When data arrives at a device, the network software looks at the port number and sends it to the right program. To find a port address, review an app’s technical documentation. PC IP Address To find the IP address of a Microsoft Windows 7/8 computer, click the network connection icon in the system tray on the computer’s desktop. Select “Open Network and Sharing Center. ” For a wired (ethernet) connection, double-click “Local Area Connection, ” then click “Details. ” Look for the IP address next to “IPv4 Address. ” For a Wi-Fi connection, double-click “Wireless Network Connection, ” click “Details, ” and find the IP address next to “IPv4 Address. ”For Windows 10, click “Start” on the desktop and select “Settings. ” Click the “Network & Internet” icon. Choose “Ethernet” on the left menu for a wired connection and select the network connection; you’ll find the IP address by “IPv4 Address. ” For a Wi-Fi connection, double-click “Wireless Network Connection, ” then click “Details. ” See the IP address by “IPv4 Address. ” Mac IP Address To find an IP address on Apple’s Mac OS X, pull down the “Apple” menu and select “About This Mac. ” When the Mac OS X version window appears, click the “System Report” button. Scroll down the list of features and settings until you see “Network” and click it. Network information appears in the right half of the window. You’ll find IP addresses next to “Ethernet” for wired connections or “Wi-Fi” for wireless. It’s possible you may have both, but in most cases you’ll have ethernet or Wi-Fi. Mobile IP Address Mobile devices such as smartphones and tablets also have IP addresses. To locate the address for an Android device, tap the “Settings” app, scroll down to “About Device” or “About Phone” and tap it, then tap “Status. ” The Status screen displays the IP address among other information. The process is similar for an iPhone or other iOS device. Tap the “Settings” app, tap “Wi-Fi, ” and tap the “info” icon (an “i” inside a circle) next to the Wi-Fi network your device is connected to. The information shown includes the IP address. Open Port Scanner Internet security is an important issue for any business. One of the tools available to computer security technicians is the port scanner, a program that searches your network for possible open port numbers that might give an outside hacker access to your business. When the program finds open ports, the technician blocks them when necessary by reconfiguring the router – the box that connects your local network to the internet.
Difference between IP address and Port Number
1. IP address:An Internet Protocol address (IP address) is the logical address of our network hardware by which other devices identify it in a network. IP address stands for Internet Protocol address which is an unique number or a numerical representation that uniquely identifies a specific interface on the network. Each device that is connected to internet an IP address is assigned to it for its unique dresses in IPv4 are 32-bits long example, 12. 244. 233. 165 And Addresses in IPv6 are 128-bits example, 2001:0db8:0000:0000:0000:ff00:0042:7879 2. Port Number:Port number is the part of the addressing information used to identify the senders and receivers of messages in computer networking. Different port numbers are used to determine what protocol incoming traffic should be directed to. Port number identifies a specific process to which an Internet or other network message is to be forwarded when it arrives at a server. Ports are identified for each protocol and It is considered as a communication are represented by 16-bit numbers. 0 to 1023 are restricted port numbers are as they are used by well-known protocol services. 1024 to 49151 are registered port numbers means it can be registered to specific protocols by software corporations and in last 49152 to 65536 are used as private ports means they can be used by anybody.
