IP Address???

If you ever wonder about the internet, IP address might always be the word that rings at the back of your mind. Whether it’s your online job or it’s your web study, IP address is inevitable. In this blog, we will oversimplify IP address so that you’re good to go when it comes to IP.

WHAT IS IP ADDRESS?

IP Addresses are the physical addresses given to the end users(networking devices) on the internet so that they can communicate with each other. Basically, IP address pinpoints the exact location of the device so that it can retrieve the information it wants from the internet. Just as your house number helps delivery man search your house easily to provide your parcel, IP address does a similar job of offering your data packet throughout internet via Internet Service Provider(ISP). IP address holds hosting information to formulate communication.

HOW DOES IT LOOK LIKE?

IP Address is the notation of strings. However, it’s virtual. There are two widely used IP standards and both have different notation format. IPv4 is a set of 4 numbers separated by a dot(.); however, IPv6 is a notation of eight hexadecimal characters separated by a colon(:). Figure aside represents those two IP standards.

WHO PROVIDES IP ADDRESSES?

IANA(Internet Assigned Number Authority) is responsible for globally providing IP Addresses. In the there was a disparate system for allocating IP. To overcome that unfair situation IANA was formed. IANA provides large IP packages to RIRs( Regional Internet Registries) which then distribute IP addresses to end users. There are five different RIRs for facilitating around different global regions:

  1. African Network Information Centre (AFRINIC)
  2. American Registry for Internet Numbers (ARIN)
  3. Asia-Pacific Network Information Centre (APNIC)
  4. Latin America and Caribbean Network Information Centre (LACNIC)
  5. Reseaux IP Europeens Network Coordination Centre (RIPE NIC)

EXTRA:

There are approximately 3.4 billion IPv4 addresses. That number is not sufficient now to handle billions of devices that have already surpassed IPv4 addresses in number. However, we are still able to connect our devices to the internet even in 2019. It’s IPv6 because of which we are still able to connect our multiple communicating devices to the internet. We still think IP address as IPv4 but, in reality, IPv4 has long been used up. Address space for IPv6 is 2128 i.e.340,282,366,920,938,463 ,463,374,607,431,768,211,456. Yeap, that’s right this figure is the actual numbers of IPv6 that’s available. Just imagine of much many devices would require to fulfil this number.
