IP stands for Internet Protocol, an address that consists of numbers, separated by periods, assigned to you by your Internet Service Provider (ISP). It servers as an identifier for each device connected to the internet.
IP addresses are also used for domain names on the web.
There are two types of IP Addresses. IPv4 and IPv6
IPv4: Internet Protocol version 4 is an old and most used version of IP address. It was deployed in the early 1980s. IPv4 addresses are 32-bit long and contain five classes, ranging from A to E. That 32-bit address space provides almost 4.3 billion unique addresses. Although some IP blocks are reserved for particular uses.
An example of an IPv4 address:
IPv6: Internet Protocol version 6, the recent version of the IP address. When IPv4 was deployed. At that time, internet devices were rare. The accelerated growth in the internet of things (IoT) and the unconstructive growth of IPv4 addresses led to the fear of a shortage of IPv4 addresses. IPv6 addresses are 128-bit long and contain both numbers and letters. That 128-bit address space provides almost 340 undecillion (36 zeros) unique addresses. In other words, IPv6 addresses contribute 1,028 times more addresses than IPv4.
An example of an IPv6 address:
No doubt, with time, the internet world is adopting IPv6. Google also manages public stats for IPv6 that show the percentage of all traffic to Google sites over IPv6 compared to IPv4. You can also verify if a domain is using IPv6 on their network by IPv6 compatibility check.
|IPv4 addresses are 32-bit long and contain five classes, ranging from A to E.||IPv6 addresses are 128-bit long and have both numbers and letters.|
|IPv4 addresses have four numbers separated by dots.||IPv6 addresses have hexadecimal numbers separated with a colon(:).|
|32-bit address space provides 4.29 billion IPv4 addresses||128-bit address space provides 340, 282, 366, 920, 938, 463, 463, 374, 607, 431, 768, 211, 456 unique IPv6 addresses.|
|IPv4 address has a header size of 20 to 60 bytes.||IPv6 has a header size of 40 bytes fixed.|
|IPv4 supports both manual and DHCP address configuration.||IPv6 supports auto and renumbering address configuration.|
|In IPv4 address checksum field is available.||In IPv6 address checksum field is unavailable.|
|In the IPv4 address, packet flow identification is not available.||In IPv6 address, packet flow identification is available and uses a flow label field in the header.|
|In IPv4 address, the Maximum Transmission Unit (MTU) stands at 576 bytes.||In IPv6 address, the Maximum Transmission Unit (MTU) stands at 1280 bytes.|
You can also perform IPv4 to IPv6 conversion as per your need.
The easiest way to verify your router's public IP address is to search "What is my IP address" on Google. Google will show you the result at the top of the page. However, our IP tool further shows the geolocation, ISP, browser, operating system, and more.
An IP address is a must-have thing if you want to use the internet. You need an IP address to surf the internet. Surfing the internet means browsing websites, uploading and downloading files over the internet, or sending or receiving emails.
IP Addresses are assigned to devices, not to humans. IP addresses are assigned to a host dynamically as they connect the network or persistently by the host hardware or software configuration.
Every internet connection has a unique IP address if it's not shared among different users by your ISP—the IP address of your computer or mobile device changes whenever you switch to some other network connection. For example, if you go outside your home and connect with some coffee shop's wifi, your device is assigned a new IP that differs from your home internet IP.
Every website or email recipient knows your IP with whom you interact. When you browse any website, a request is initiated from your computer to the website's server. The request holds your IP address. Likewise, suppose you send an email to someone. In that case, the email recipient knows which IP address is used to send an email and can found the sender's IP by tracing an email.
Your ISP knows your name and physical address. It can also determine your internet activity, like which sites you browsed and the files you downloaded. However, your ISP never reveals your personal information and data to anybody. They maintain the users' privacy and only disclose the personal data if the court orders to do so.
The IP location lookup only provides your country, ISP, state, city, latitude, and longitude if anyone tries to find your IP location. They cannot get personal information, e.g., name, physical address, age, gender, from your IP.
Your IP address reveals your geolocation on the map. First, the IP location lookup provides you the location of your public IP address. Second, that location is not 100% accurate—usually, it's the location of your ISP.
Sure, you can hide your actual IP address from everyone connected with you via the internet. IP can be hidden by using any proxy service or a VPN. After connecting with a VPN, your real IP will not be disclosed to anyone receiving a request from your computer. It works by re-routing all your internet traffic through some other computer in the world. Many VPN service providers are in the market, with both free and paid plans.
Even the police can't track live, encrypted VPN traffic, but they can go to your ISP and request connection or usage logs if they have a court order. Since your ISP knows you're using a VPN, they can direct the police.
A public IP address is used to communicate outside the network and is allocated to electronic devices for direct access to the internet. A private IP address is assigned to electronic devices within your network without exposing them to the internet world.
Two computers cannot have the same public IP address unless they are connected through the same router. If they are connected through the same router, they can have the same public IP address but different private IP addresses.
Whenever an electronic device connects with the internet, your ISP assigned it an IP. When you are at home, you have a different IP address, but you have a different IP address at a coffee shop or any other place, which means you cannot carry your IP. Moreover, when you reset your modem, it will also reset your IP address.
The IP blacklist checker instantly checks your IP in anti-spam databases to know whether an IP is blacklisted or not. Sometimes, the company blocks the whole slot of IPs using ASN. You can perform the ASN WHOIS to find the assigned owner, location, contact information, and abuse reporting details for any ASN.
Yes, any website you visit can monitor your online activity. That includes which pages you visited, how much time you spent on each page, and the sequence of your browsing. All can be recorded through third-party applications (like Google Analytics) that run in your browser, which sends each activity you perform on a website.
