![]() When a user types a domain name like ‘’ into their browser window, this begins a DNS query which ultimately leads to a DNS server translating the domain name into an IP address. It works like a phone book for IP addresses so that users can access web services using human-friendly domain names. The system that orchestrates all this is called DNS. Using the provided IP address, Google can send a response back to the user’s device, which will then display that content in the user’s web browser. For this reason, the request will contain the asker’s IP address. Once Google receives the request, it needs to know where to send the website content. Without that address, the pizza delivery person will have no idea which house to deliver the pizza to.įor example, when a user types a domain name, like, into a web browser, this will initiate a request to Google’s web server asking for content (the Google homepage). If someone calls a pizzeria to order a delivery, they need to provide their physical address. The Internet Protocol solves this by assigning IP numbers to every device accessing the Internet.Ī computer’s IP address is like the physical address of a house. With billions of people accessing the Internet every day, unique identifiers are necessary to keep track of who is doing what. ‘IP’ stands for Internet Protocol, which is the set of rules that makes it possible for devices to communicate over the Internet.

Both versions can run in parallel but must implement special measures to facilitate communications between IPv4 and IPv6 devices. Despite the difference between IPv4 and IPv6, both are concurrently used on the web for a decade. IPv6 provides some updates to IPv4, including security and performance features. IPv6 means Internet Protocol version 6, which is the latest version of IP address. That leads to the shortage of IPv4 addresses. But due to technological development, the IPs are improperly distributed. Its 32-bit long means that you have 4.3 billion unique IP addresses. It was implemented in 1983, and still today, the users are mostly aware of that version. IPv4 means Internet Protocol version 4 is the most used version of IP address. IPv4 and IPv6 are the versions of IP addresses.
