Except sleeping, most of the time, we spend our important time on the internet in our modern life. On a day-long, we visit many websites, Purchase product from online, communicate other in the social platform and as needed we stay connected in the more various online platform. To do our online job we use a human-readable address but computers can’t understand our human-readable address. So, the question is how computers work using human-readable addresses. To understand the human-readable address computers use a converter known as DNS who converts the human-readable address to the IP (Internet Protocol) Address. So today our discussion is about IP Addresses.

What is IP Address?

IP (Internet Protocol) Address is a string of numbers that is separated by periods. It is expressed as a set of four numbers. For example, 192.168.02.06 is an IP Address. Usually, these numbers are separated into four parts by three dots. The separated parts by dot consist of a byte. We know every bite is equivalent to 8 bits. So, an Internet Protocol Address consists of 32 bits and it is capable to provide roughly 4 billion unique numbers.  Each number in the set can go from 0 to 255.  In this way, the full IP addressing range can be from 0.0.0.0 to 255.255.255.255. This address is unique for all computers like a phone number and it’s a language to communicate with each other over a network.

IP addresses are not arbitrary. They are numerically created and dispensed by the Internet Assigned Numbers Authority (IANA), a division of the Internet Corporation for Assigned Names and Numbers (ICANN). ICANN is a non-profit organization that was set up in the United States in 1998 to assist with keeping up with the security of the web and permit it to be usable by all. Each time anybody enrols a domain on the web, they go through a domain name registrar, who pays a little charge to ICANN to enlist the domain.

How do IP addresses work?

Web Protocol works the same way as some other languages, by imparting utilizing set rules to pass data. All devices find, send, and exchange data with other associated devices utilizing this convention. By communicating in a similar language, any PC in any area can converse with each other.

The utilization of IP addresses regularly occurs in the background. The interaction works like this:

  1. Your device indirectly connects to the internet by connecting at first to a network connected to the internet, which then grants your device access to the internet.
  2. At the point when you are at home, that network will likely be your Internet Service Provider (ISP). At work, it will be your company network.
  3. Your IP address is assigned to your device by your ISP.
  4. Your internet activity goes through the ISP, and they route it back to you, utilizing your IP address. Since they are giving you admittance to the web, it is their job to assign it to your device.
  5. However, your IP address can change. For instance, turning your modem or router on or off can transform it. Or then again you can contact your ISP, and they can transform it for you.
  6. At the point when you are out and about– for instance, travelling – and you take your device with you, your home IP address doesn’t accompany you. This is on the grounds that you will utilize another network (Wi-Fi at a hotel, airport, or coffee shop, and so on) to get to the web and will utilize an alternate (and temporary) Internet Protocol address, allocated to you by the ISP of the hotel, airport or coffee shop.

As the interaction infers, there are various sorts of IP addresses, which we explore below.

Types of IP addresses

There are different categories of Internet Protocol addresses, and within each category, different types.

1. Consumer IP Address

Every individual or business with an internet service plan will have two types of IP addresses: their private and their public Internet Protocol address. The terms public and private relate to the network location — that is, a private is used inside a network, while a public one is used outside a network.

a. Private IP Address

Private

Each device that associates with your internet network has a private IP address. This incorporates PCs, cell phones, and tablets yet additionally any Bluetooth-empowered devices like speakers, printers, or smart TVs. With the developing web of things, the quantity of private IP tends to you have at home is likely developing. Your router needs an approach to distinguish these things independently, and numerous things need an approach to perceive one another. Hence, your switch produces private IP addresses that are unique identifiers for every device that separate them from the network.

b. Public IP Address

Public IP

Public IP addresses are essential addresses related to your entire network. While each associated device has its own IP location, they are likewise included inside the main IP for your network. As depicted above, your public IP addresses are given to your router by your ISP. Commonly, ISPs have a huge pool of IP addresses that they circulate to their clients. Your public IP addresses are the address that every one of the devices outside your internet network will use to identify your network.

There are two types of Public IP Addresses.

(I) Dynamic IP Address

Dynamic IP Location

As the name proposes, dynamic IP addresses are subject to change, here and there immediately. Depending on the situation, Dynamic Host Configuration Protocol (DHCP) workers assign dynamic addresses.

We use the dynamic address in light of the fact that IPv4 doesn’t give sufficient static IP addresses to go around. In this way, for instance, a hotel likely has a static IP Location, however, every individual device inside its rooms would have a dynamic Internet Protocol address.

On the internet, your home or office might be assigned a dynamic IP address by your ISP’s DHCP server. Inside your home or business network, the dynamic IP address for your devices – regardless of whether they are PCs, cell phones, streaming media devices, tablets, what have you – are most likely relegated by your network router. Dynamic IP is the standard utilized by and for consumer equipment. ISP lets you use it temporarily. If a dynamic address is not in use, it can be automatically assigned to a different device.

(II) Static IP Address

Static IP Address

Static IP addresses are simply an address that doesn’t change. When your device is allocated a static IP address, that number commonly remains something very similar until the device is decommissioned or your network architecture changes.  Static IP addresses generally are used by servers or other important equipment.

Static IP addresses are assigned by Internet Service Providers (ISPs). Your ISP could possibly assign you a static IP address contingent upon the idea of your administration arrangement. We depict your alternatives somewhat later, yet until further notice accept that a static IP address adds to the expense of your ISP contract.

A static IP address might be IPv4 or IPv6; for this situation the significant quality is static. Sometime in the not-so-distant future, all of the arranged stuff we have might have a special static IPv6 address. We’re not there yet. Until further notice, we as a rule use static IPv4 addresses for permanent addresses.

Static vs. Dynamic: Which is best for me?

There is no ideal IP addresses answer for all individuals and all events. sometimes, it is better for a PC or device to utilize a static IP address; sometimes a dynamic IP address works best.

Choosing whether dynamic or static IP addresses are better for you likewise relies upon the nature of the connection. A static IP is bound to be pertinent for a business, while a dynamic IP is suitable for a home network.

There are two types of website IP addresses

For website owners who don’t host their own server, and rather depend on a web hosting bundle – which is the case for most sites – there are two kinds of website addresses. These are shared and dedicated.

a. Shared IP Address

Shared

Shared IP addresses are common strings that can be assigned to multiple websites. You’ll commonly find shared IP addresses with shared hosting providers or managed WordPress hosts with a cloud-based tech stack.

 

b. Dedicated IP Address

Dedicated

Dedicated IP addresses are a unique string that is simply assigned to your site. Truth be told, in the event that somebody typed your one-of-a-kind IP address into their web program’s search bar (rather than your domain name), they’d have been able to pull up your site.

What type of IP addresses are best for SSL?

Today, there’s no distinction between dedicated IP addresses and shared IP addresses with regards to SSL.

Quite a while prior, it was actually the case that you required dedicated IP addresses to encode your site with an SSL certificate. Today, most hosting providers utilize an innovation called Server Name Indication (SNI), which permits the server to utilize multiple SSL certificates on a solitary IP address.

Because of this innovation, you can add an SSL certificate to your site paying little heed to the kind of IP address it employs. (Also, you should, as adding an SSL certificate to your site is viewed as a best practice by Google.)

How to look up the IP address

The simplest approach to check your router’s public IP address is to look at “What is my IP address?” on Google. Google will show you the appropriate answer at the top of the page.

Different sites will show you similar data: they can see your public IP address on the grounds that, by visiting the site, your router has made a request and accordingly uncovered the data. The site IP location goes further by showing the name of your ISP and your city.

Generally, you will only receive an approximation of location using this technique — where the provider is, yet not the real device location. In case you are doing this, make sure to log out of your VPN as well. Getting the genuine actual area address for the public IP address ordinarily requires a search warrant to be submitted to the ISP.

In Windows

  • Use the command prompt.
  • Search for “cmd” (without the quotes) using Windows search.
  • In the resulting pop-up box, type “ipconfig” (no quote marks) to find the information.

On a Mac

  • Go to System Preferences.
  • Select network – and the information should be visible.

On an iPhone

  • Go to Settings.
  • Select Wi-Fi and click the “i” in a circle () next to the network you are on – the IP address should be visible under the DHCP tab.

In the event that you need to check the IP addresses of different devices on your network, go into the router. How you access the switch relies upon the brand and the software it uses. For the most part, you should be able to type the router’s gateway IP address into a web browser on the same network to access it. From that point, you should explore something like “connected devices,” which should show a rundown of the relative multitude of devices as of now or as of late joined to the network — including their IP addresses.
