Let’s suppose that you ask any of the search engines the question ”what is IP address”. Many links related to your query, as well as the link of this article you are currently reading, will be listed on the screen of your device within a few seconds. This is nothing more than a data exchange in the background of the internet world. This data exchange which can also be called as “communucation between asking and answering parts of the virtual world” is provided by IP addresses. To make it a little more simple and clear, we can say that, all devices connected to a network can talk to each other by using their IP addresses.
An IP address is a unique identifiction number of a device connected to a network (modems, routers, computers, smart mobile phones, printers, smart televisions etc.) IP addresses help each dvice in a network recognize each other and enables electronic data transmission.
Working logic of internet is constructed on the need to differentiate computers, web sites and network providers from each other. This is the point why an IP address becomes as a necessity.
All internet activities such as website visits, sending /receiving e-mails, watching videos in youtube are in fact nothing but an electronic data exchange between the requester and provider. In order this data exchange to be managed, there is an important question to be answered first.
“Who is requesting data/who is providing data, How do they know each other?”
The correct answer is IP address. Excluding MAC, it would exactly be right to say that an IP address is the ID number of a device.
An IP address is a crutial element of Internet Protocol. It is designed as a group of numbers and can be assigned automatically or manually.
IP addresses are produced and allocated by IANA (Internet Assigned Numbers Authority) a subdivision of ICANN (Internet Corporation for Assigned Names and Numbers). ICANN is a non profit organization established in USA in 1998. It helps to protect the security of the internet and make it usable by all.
IP addresses are consisted of a set of four number of groups. Each number in the set can range between 0 and 255.
An IP address comprises two basic components. Network ID and Host ID.
Network ID comprises the first three group of numbers and identifies which network is used to connect to the internet. Host ID refers to a specific device used, connected to a network. It is the fourth number of the group in an IP address.
Electronic devices suh as computers, smart phones have no direct access to internet.The connection is only available through a modem or a router. Basically, your computer connects to your modem/router and the router connects to the internet.
The devices connected to the same local netwok can exchange electronic data between each other without the need of internet. In another words, internet connection is not required for electronic data transmission within the same local network. But on the other hand, once a WAN (internet) is established, different devices within different local networks can send/receive electronic data to/from each other.
IP address: 192.168.1.2
Network ID: 192.168.1
Host ID: .2
When there is more than one device connected to the same network, network ID of the IP address will remain the same. However, host ID will differ for each device.
Laptop 1: 192.168.1.1
Laptop 2: 192.168.1.2
Smart phone: 192.168.1.4
Smart TV: 192.168.1.5
Some of the IP addresses have direct access to the internet which is called as “wide network” while the others can only access the devices within a local network and need a modem for internet connection.
IP addresses can be divided into two main categories. Private IP and Public IP. Public IP addresses can also be divided into two subtypes which are called as dynamic and static IP.
Each device which does not have direct access to internet and needs a server, proxy or NAT (Network Address Translation) has private IP address.
The computers and smart phones we use at home have private IP addresses. That kind devices need a modem in order to connect to the internet. However, they can exchange electronic data between each other within the same network.
Enter “ipconfig” in the command (CMD) prompt. You will reach informations such as local network IP and network card features. Please click to get detailed information about CMD commands.
Enter “ifconfig” in the terminal application. You will get all information about your local network.
Android phones: Click the network name in the Wifi settings
IOS phones: Click "i" button next to the network connected
Public IP addresses are required to access the internet. These addresses are used to recognize all devices within or outside of a local network.
Public IP addresses are assigned by internet service providers (ISP). The IP assigned to your modem by ISP is a public IP address. When we connect to the internet, it is not the private IP of our device. Instead, the connection is managed by public IP of our modem. All online connections outside a local network such as sending/receiving e-mails, online shopping and internet surfing require a public IP address.
All internet activities are carried out through public IP addresses. In case a fraud or illegal transaction notification is received by internet service providers, it is easy to find the user just by checking public IP address.
The easiest way to find a public IP is to search for it on a web site. ipadresim.com offers you the tools to search for your public IP and also to access details such as browser information.
Now, lets have a look at the subtypes of public IP addresses which are called as dynamic and static IP.
The expression “Dynamic” means that the IP address is changing time to time, when your modem reconnects to service provider or even while surfing in the internet. Dynamic IP addresses are assigned automatically by internet service providers within the framework of the DHCP (Dynamic Host Configuration Protocol).
So, what happens to the old IP address? Selfdestruct? Disappear?
The answer is no. Within the scope of DHCP, it is stored in a kind of recycling pool and reassigned to another modem . This movement of dynamic IP addresses generates cost savings for internet service providers. In addition, changing IP address regularly will build a security shield against hacker attacts.
Static IP addresses do not change and stays the same once it is assigned. Static IP addresses are generally used for VPN servers, websites, game servers etc. The most important reason for being preferred, is that static IP addresses are not changeable and remains the same . Guess how it would be, if IP addresses of the websites you visit everday changing all the time.
Before getting into how IP addresses work, it would be helpful to have a look at working logic of internet first.
The internet, we can also call as a backbone of the web, has become an indispensable part of our daily lives. It is a huge electronic communication network, that connects all global devices under the rules of TCP/IP. TCP /IP protocols both define the rules of electronic data exchange and messaging between computers over a network.
Electronic devices such as computers need an internet service provider (ISP) with an internet access, in order to connect to the internet. In another words, internet connection for such devices is managed over an ISP. The IP address is assigned to the computer by ISP, access to a websites is managed over ISP, search results are directed to the computer by ISP. As a result, all electronic data requests and transmissions in the background of internet world are carried out by using IP addresses assigned by ISP.
Since IP addresses are complex group of numbers and hard to to remember, the easiest way to access a web site is to use web address which is called as URL. However, web sites can also be accessed entering IP addresses in case it is known.
