Your Public IP is:
What is My IP tells your Public IPv4 & IPv6 address. That address is assigned to you by your ISP. The IP may be dynamic or static, which means it can change by every connection reset or remain the same with re-connection.
"IP" stands for internet protocol; the set of protocols makes the devices possible to communicate over the network. With billions of users accessing the internet daily. It's important to track who is doing what. Internet protocol makes it possible by assigning a unique identifier to each device on the internet.
A device's IP address is like a physical house number. When the user enters the website address in its browser bar, it will request the website's server for the content. When the website's server receives the request, it wants to know to whom it should send the content. For that, it needs the client's IP address. Therefore, the request contains the client's IP. Using that IP, the website's server can respond to the user's device, displaying that content in the user's web browser.
IPv4 and IPv6 are the versions of IP addresses.
IPv4 means Internet Protocol version 4 is the most used version of IP address. It was implemented in 1983, and still today, the users are mostly aware of that version. Its 32-bit long means that you have 4.3 billion unique IP addresses. But due to technological development, the IPs are improperly distributed. That leads to the shortage of IPv4 addresses. Therefore, IPv6 was introduced.
IPv6 means Internet Protocol version 6, which is the latest version of IP address. Its 128 bit long means that you have 340,282,366,920,938,463,463,374,607,431,768,211,456 unique IP addresses.
IPv6 provides some updates to IPv4, including security and performance features. Despite the difference between IPv4 and IPv6, both are concurrently used on the web for a decade. Both versions can run in parallel but must implement special measures to facilitate communications between IPv4 and IPv6 devices. That compromise had to be made because a majority of the web is still running on IPv4 addresses.
The shortage of IPv4 addresses led to the introduction of dynamically assigned IP addresses, which is still a pervasive and cost-cutting strategy. For example, when the home user connects to the internet with its laptop, its ISP assigns it a temporary IP address from the pool of shared IP addresses. That IP address is a dynamic IP address. That can be reset with every connection reset.
However, large ISPs or enterprises pay for maintaining the static IP (like Cloudflare 18.104.22.168).
For regular users, the dynamic IP is sufficient. However, for web hosting companies, API, or game servers, the dynamic IP can create problems. A change in the IP address can cause their DNS query to fail, effectively taking the resource offline.
If you want to know your IP address, go to Google and type "What is my IP." Google will show you your public IP address. But our What is my IP tool takes the thing a little further. With your IP address, it will also show your IP's country, state, city, ISP, location on a map, and much more.
