Internet Protocol and regulations

The internet protocol is a set of rules, a contract for addressing and routing the packets of data so that they can get transferred across the network and retrieve back at specific locations. Data transfer on the internet is divided into little pieces known as packets. With each package, significant IP information is attached so that it helps the routers to transfer the packets to the right destination. Every system or domain that is used to connect to the network resources is assigned a unique IP address.

Once the packet reaches its certain destination, they are handled in different ways depending on the type of transfer protocol that is used in combination with the IP. The two most common transport protocols are UDP and TCP. This blog intends to mention every bit of detail on internet protocol and its regulations.

Why Network Protocol is significant?

In network resources, there is a protocol or standardised way of doing specific actions and data formatting data which helps two or more devices to communicate with each other. To comprehend why protocols are so crucial, let us consider the process of mailing a post. We tend to follow a standardized way to mention name, city, street address, zip code and state on the envelope. If we leave out a single thing on the envelope, there is a possibility that the post office won’t deliver it. So there is an agreed-upon protocol for mentioning address in a certain way for the postal organisation to work. In the very same way, all data packets must tag along with certain information in a certain order, so that it can be delivered. IP addresses follow the same procedure in a standardized format.

How does an IP address work?

The network is made up of several interconnected substantial connections, each of them responsible for specific blocks of IP addresses. These large networks are also known as Autonomous System (AS). Several routing protocols such as BGP, help to route the packets across the autonomous system based on their destined IP addresses. Routers along with tables which indicates the ASes on which the packets should travel to reach their destination. Packages go through the various autonomous system until one of them claims responsibility for the destined IP address. Than that independent system internally routes the data packets to their destination.

Please note that data packets can take different routes to the same destination if it seems necessary. Just as a gang of people driving to an agreed-upon destination through different roads to get there.

Internet Protocol Packet

Adding an IP header to every packet before it gets sent to its way creates an IP Packet. An IP header is basically a list or series of binary bits, and it creates a record of several bits of information about the package including the IP address of sender and receiver system. IP header also contains information regarding:

  • Packet length
  • Header Length
  • TTL ( TIme to live decides the number of network resources the packet have to travel before it is discarded permanently)
  • The used transport protocol (TCP, UDP, SMTP etc)

Versions of Internet protocol | IPv6 Vs IPv4

The fourth edition of IP was introduced in 1983. Just as there are so many possible permutations for a license plate in automobile and then they have to be reformatted again periodically, the supply of accessible IPv4 addresses became depleted. IPv6 characters have much more characters and permutations. However, IPv6 is still not completely adopted and much devices and domains still follow IPv4 addresses.

Detailed comparison between IPv4 and IPv6

Types of Internet protocols

Several protocols are currently accessible on the internet which includes TCP (transmission control protocol), UDP (user datagram protocol), HTTP, FTP (file transfer protocol), Electronic mail, TELNET and much more. Further, in the blog, we will discuss more these types of the internet protocol.

Transmission Control Protocol

TCP is a transfer protocol, which means it dictates the route on which data is sent and received. The data portion of each packet includes a TCP header which uses TCP/IP. Before initiating the transmission, TCP tends to open a connection with the recipient. It makes sure that all packets get received in particular order once the transfer began. At the recipient end, the transmission will acknowledge receiving every package that arrives. The missed packages are sent again if the recipient does not recognise.

TCP is designed for its reliable sources and not the speed because TCP ensures that all packets arrive in a particular order. Also loading the data packets using TCP/IP can take longer than usual if some of the data packets go missing.

TCP and IP are formely designed to be used along with each other and both of them are also referred as TCP?IP suite. However, various other transport protocols is also used with the IP suite.

User Data gram Protocol (UDP)

The most used transfer pr. It sends the data packet faster as compared to TCP but it is also less reliable than the TCP. UDP does not ensure that all data packets are sent in a certain order, and it does not tend to establish a connection with the recipient.

UDP is often utilised for streaming videos and audios, as these data packets can take the risk of dropping packages while transferring because there is a constant need for real-time transmission while streaming. For example, if a user is streaming a video online, there is no need for every pixel to be present in each frame of the video. User is entitled to stream the video at average speed than sit and wait for the data retrieval of every bit or pixel.

Hypertext transfer protocol (HTTP)

HTTP is known as a communication protocol, and it is used to define the mechanism of communication between the web server and browser. It is also refereed as request and response protocol because the communication between a server and the browser takes place in ” ask and provide” manner.

HTTP requests the web server which contains a request line, header file along with the message body. The first line of the request line specifies the required access whether it wants to post something or get access. The header is subjected to indicate the server’s domain name where index in htx format is retrieved. Http response also has the same structure of the status line, headers along with the message body.

E-mail

We all have heard about the email service which allows the user to send messages in electronic mode. E-mail is by far the most efficient, almost free and the real-time mean of sharing information.

E-mail address is generally in format of username@domain. Email is generally included in three distinct protocols.These protocols are

  • Simple mail transfer protocol (SMTP)
  • Internet Message access Protocol (IMAP)
  • Post Office Protocol 3 (POP3)

POP3 and IMAP are used for receiving emails while SMTP is a designed protocol for sending. Almost every network service provider supports one or other form of these protocols. However, the most stand out against all three of them is SMTP for sending emails and POP3 for receiving.

File Transfer Protocol

FTP which is short for File transfer protocol, a mean of transferring a file from one system to other. FTP is mostly used to upload a website or web page on a server so that it can be accessed on World Wide Web. A special program known as a client is usually needed to configure FTP.

Usenet (news)

NNTP ( Network News Transfer Protocol ) is based on for serving Usenet is similar to the forums of many websites. Usenet gives access to forums that are dedicated to certain organisations or a specific range of topics. Some of the forums included in Usenet are of comp. as their suffix which implies that the forum is based on discussion related to computer. Similarly sci. is used for scientific discussions and rec. is a discussion portal for games and hobbies.

Golpher

Gopher is another tool of the internet, a menu-based program which enables the user to browse information without having any information about their sources. It lets you view and searches a list of resources that sends the material to their user.

Conclusion

In conclusion, an IP address is a numerical label assigned with every device which participates in any form of a computer network. An IP address serves twp of the most important aspects of network security: Location address and network or host interface identification.
