What is IP address and types of IP address - IPv4 and IPv6 | TechTerms transcript

hey guys this is DG today we are going to understand what is an IP address and how you can find your computers or your smartphone's IP address so let's start computers in Internet communicate with each other with underground or underwater cables or wirelessly if I want to download a file from internet then my computer should have an address so that other computers in Internet can find and locate my computer in Internet terms that address of computer is is called IP address let us understand it with other example like if someone wants to send you a mail then he or she should have your home address similarly your computer also needs an address so that computers in Internet can send you a file that you want to download that address in Internet terms is called IP address which is nothing but a string of numbers written in a certain format note this comparison this is your home address which is identified by your area Postman and you get all the things delivered in this address similarly this is your computer address which is identified by the computers in Internet and you get all the downloads available at this computer address this address is the IP address of your computer IP address stands for Internet Protocol address but what does this mean Internet Protocol is a set of rules that makes internet work you are able to watch this video this time in YouTube only because your computer or your smartphone has an IP address and YouTube is sending you all the data related to this video to this IP address IP address is of two types Internet Protocol version 4 and Internet Protocol version 6 Internet Protocol version 4 consists of four numbers separated with the dot each number can range from 0 to 255 in decimal numbers but computers do not understand these decimal numbers so these numbers are converted to Binary form which is computer understandable therefore in binary this range can be written as 00 00 0 00 0 to 1 1 1 1 1 1 1 1 since each number n is represented by a group of eight binary digits so the whole ipv4 address is represented by a sequence of 32 ones and zeros or simply I should say by a sequence of 32 bits so ipv4 is a 32bit address in ipv4 a unique sequence of ones and zeros is assigned to each computer therefore a total of 2 to power 32 devices that is approximately 4 billion devices can be addressed and connected to internet with ipv4 but there is a problem with this 32-bit ipv4 address with ipv4 we can connect only this amount of devices to internet but these days we have devices like computers smartphones for more than 4 billion so slowly we are moving towards IP V6 address which is a 128bit IP address in human friendly form IP V6 is written as a group of eight hexade decimal numbers separated with colons for example in human friendly form the IPv6 address can be written like this while in computer friendly form IPv6 address can be return by a sequence of 128 ones or zeros since a unique sequence of ones and zeros is given to each computer connected to Internet so with IPv6 a total of 2 to^ 128 devices can be connected to Internet that is IP P V6 can address this amount of devices which is actually far more than enough for many future generations to find your computer's public IP address write what is my IP in www.google.com Google will tell you your computer's public IP address similarly to find your smartphone's public IP address write or just say what is my IP in your smartphone Google will tell you your smartphone's public IP address without this numeric protocol we would not be able to connect to internet and without internet we would be standing in Long cues to get our train tickets we would be looking at newspapers to see where jobs are available and we would be buying storage devices like CDs because without internet cloud storage would not work so IP address is must for internet connection IP address can be classified as Dynamic IP address and static IP addresses starting with Dynamic IP addresses when you connect your device like smartphone or computer to internet internet service provider provides you an IP address from the range of available IP addresses now your device has an IP address so you can connect your device to internet and send and receive data to and from the computers in Internet next time you connect your device to internet your internet service provider provides you some different IP address but from the same available range since IP address keeps on changing every time you connect your device to internet so such IP addresses are called Dynamic IP addresses now static IP addresses static IP addresses never changed they serve as permanent internet address static IP addresses are used by DNS servers what are DNS servers actually the these are computers that help you to open a website in your computer static IP addresses provides information such as device is located in which continent which country which city and which internet service provider provides internet connection to that device once we know who is the internet service provider we can trace the location of the device connected to Internet therefore IP address allows billions of digital devices to be pinpointed static IP addresses are considered somewhat less secure than Dynamic IP addresses because they are easier to track however following safe internet practices can help you to keep your computer secure no matter what type of IP address you use if this video was helpful to you and you have learned something from this video then please like this
