IP Address Determined

IP stands for Internet Protocol, an address composed of numbers separated by dots, assigned by your Internet Service Provider (ISP). It serves as an identifier for every device connected to the Internet.

IP addresses are also used for domain names on the Internet.

Types of IP Addresses

There are two types of IP addresses: IPv4 and IPv6.

IPv4: Internet Protocol version 4 is the older and most commonly used version of IP addresses. It was deployed in the early 1980s. IPv4 addresses are 32 bits long and consist of five classes from A to E. This 32‐bit address space provides nearly 4.3 billion unique addresses, although some blocks are reserved for specific purposes.

Example of an IPv4 address: 32.253.431.175.

IPv6: Internet Protocol version 6 is the latest version of IP addresses. Due to the rapid growth of the Internet of Things (IoT) and the limitations of IPv4, IPv6 was developed. IPv6 addresses are 128 bits long and contain both numbers and letters, providing an exponentially larger address space than IPv4.

Example of an IPv6 address: 2001:4860:4860:0000:0000:0000:0000:8888

This is the expanded form of an IPv6 address for one of Google’s DNS servers. The expanded form can also be compressed.

Over time, the internet is expected to fully adopt IPv6. Google publishes statistics showing the percentage of traffic to its sites using IPv6 compared to IPv4. You can also verify if a domain uses IPv6 by checking its compatibility.

IPv4 vs. IPv6

IPv4	IPv6
IPv4 addresses are 32 bits long and consist of five classes from A to E.	IPv6 addresses are 128 bits long and contain both numbers and letters.
IPv4 addresses consist of four numbers separated by dots.	IPv6 addresses are represented in hexadecimal numbers separated by colons (:).
The 32‐bit address space provides approximately 4.29 billion addresses.	The 128‐bit address space provides approximately 340,282,366,920,938,463,463,374,607,431,768,211,456 unique addresses.
IPv4 header size ranges from 20 to 60 bytes.	IPv6 has a fixed header size of 40 bytes.
IPv4 supports both manual and DHCP configuration.	IPv6 supports automatic configuration and renumbering.
IPv4 includes a checksum field.	IPv6 does not include a checksum field.
IPv4 does not support packet flow identification.	IPv6 supports packet flow identification using a flow label in the header.
The maximum transmission unit (MTU) for IPv4 is 576 bytes.	The MTU for IPv6 is 1280 bytes.

How to Look Up IP Addresses?

The simplest way to check your router’s public IP address is to search “What is my IP address” on Google. Google displays the result at the top of the page. Our IP tool, however, also shows geolocation, your ISP, browser, operating system, and more.

FAQ

Do I Need an IP Address?

An IP address is essential for using the Internet. It is required for browsing websites, downloading and uploading files, and sending or receiving emails.

How Are IP Addresses Assigned?

IP addresses are assigned to devices, not people. They can be assigned dynamically when a device connects to a network, or statically through hardware or software configuration.

Your IP address changes depending on the network you are connected to. For example, your home IP address will differ from the one you receive when connecting to a café’s Wi-Fi. Additionally, resetting your modem can result in a new IP address.

Who Knows My IP Address?

The website you visit or the recipient of your email can see your IP address. When you access a website, your computer sends a request to its server, which includes your IP address. Similarly, when you send an email, the recipient can trace the IP address used.

Can Someone Find My Personal Details Using My IP?

Your ISP knows your name and physical address, but it does not disclose your personal details unless required by law. They keep user information confidential.

What Can Someone Do With My IP Address?

An IP lookup can only reveal general information such as your country, ISP, state, city, latitude, and longitude. It does not provide personal details like your name or exact physical address.

Can Someone Track Me by My IP Address?

Your IP address gives a general location on a map, usually indicating the area of your ISP rather than your precise location.

Can I Hide My Real IP?

Yes, you can hide your real IP address using a proxy or VPN service. This reroutes your internet traffic through another server, masking your true IP address. There are many VPN providers available offering both free and paid services.

What Are Public and Private IP Addresses?

A public IP address is used for external communication and is assigned to your device for direct access to the Internet. A private IP address is used within your local network and is not visible on the internet.
