In the world of technology, the internet plays a crucial role in our everyday lives. Whether you’re streaming your favorite shows, playing video games, or simply browsing social media, every action on the internet is powered by something called an IP address. In this blog, we’re going to take a closer look at what an IP address is, and specifically dive into one example: 104.19.245.19.

You might be wondering, “What’s the significance of this number?” Well, by the end of this blog, you’ll have a clear understanding of what 104.19.245.19 means, how it works, and why IP addresses are so important.

What is an IP Address?

An IP address (Internet Protocol address) is a unique string of numbers that identifies a device connected to a network, like the internet. Think of it like a home address for your computer, phone, or any other device connected to the internet. Just like how the postal system uses your home address to deliver mail, the internet uses your IP address to send information to the correct place.

For example, when you type in a web address like www.google.com in your browser, your computer doesn’t actually know what “Google” is. Instead, it converts that web address into a unique IP address to find Google’s servers and then loads the page for you.

IP Address Format

IP addresses are typically written as a series of four numbers, each separated by a period (.). These four numbers are called octets because each can range from 0 to 255, making up a 32-bit number in total. Here’s the format:

• 104.19.245.19

This specific IP address is an example of an IPv4 address, which is the most commonly used version of IP addresses today.

What Does 104.19.245.19 Mean?

So, what exactly does 104.19.245.19 represent? Let’s break it down.

This is an IPv4 address, meaning it has four octets. Each octet represents a different part of the network:

• 104: This first number is often referred to as the network part of the address. It helps identify the large network the device belongs to.
• 19: The second octet can also be part of the network, depending on the type of network.
• 245: The third octet is typically used for the subnet, a smaller network within the main network.
• 19: The last octet is the host or device part, which identifies the specific device (like a computer or phone) on the network.

Together, these numbers allow devices to communicate with one another on a network. For example, if your computer has the IP address 104.19.245.19, other devices can use this address to send information directly to your machine.

Public vs. Private IP Addresses

There are two main types of IP addresses: public and private.

• Public IP Address: This is the address that your device uses to connect to the internet. Public IP addresses are unique across the whole web, so no two devices can have the same public IP at the same time.
• Private IP Address: These are used inside a local network, like your home Wi-Fi. If you have multiple devices connected to your home router (a phone, tablet, laptop, etc.), each device will have its own private IP address. Private IP addresses can be reused across different networks because they are not visible on the open internet.

The IP address 104.19.245.19 is a public IP address. This means that it’s visible on the internet and is likely assigned to a specific website or service.

IPv4 vs. IPv6

We mentioned earlier that 104.19.245.19 is an IPv4 address, but there’s also something called IPv6. What’s the difference?

• IPv4 (Internet Protocol version 4): This is the older and more widely used version of IP addresses. It uses 32 bits to create about 4.3 billion possible addresses. While that might sound like a lot, with the growth of the internet, we’ve actually started running out of IPv4 addresses!
• IPv6 (Internet Protocol version 6): IPv6 was created to solve this problem by using 128 bits, allowing for trillions upon trillions of unique IP addresses. While IPv6 is slowly being adopted, most of the internet still runs on IPv4 addresses like 104.19.245.19.

How Are IP Addresses Assigned?

IP addresses like 104.19.245.19 aren’t random; they’re assigned by a central organization called the Internet Assigned Numbers Authority (IANA). IANA delegates blocks of IP addresses to smaller organizations called Regional Internet Registries (RIRs). These RIRs then assign IP addresses to internet service providers (ISPs), who finally assign them to customers like you.

For example, when you connect to the internet from your home, your ISP will give your router a public IP address, like 104.19.245.19. If you’re using a website, that site also has its own IP address, which allows your device to find and communicate with the site’s servers.

How Does 104.19.245.19 Fit Into DNS?

One thing you might be curious about is how IP addresses and domain names (like google.com) work together. This is where something called DNS (Domain Name System) comes into play.

DNS is like the phonebook of the internet. When you type a web address into your browser, the DNS converts that name into the corresponding IP address. For example, www.example.com might actually point to the IP address 104.19.245.19. Without DNS, you’d have to remember every website’s IP address instead of its name!

Why Are IP Addresses Important?

IP addresses like 104.19.245.19 are crucial to how the internet functions. Here are a few reasons why they’re so important:

1. Communication: Without IP addresses, devices wouldn’t be able to find and communicate with each other. Your computer wouldn’t know where to send requests, and websites wouldn’t know where to send the information.
2. Routing: Routers use IP addresses to send data between networks. Every time you visit a website, your data is split into small pieces (called packets), which travel across the internet. Routers use IP addresses to make sure those packets end up in the right place.
3. Security: IP addresses also play a role in internet security. Websites and services can block or allow traffic from specific IP addresses, and firewalls use them to protect networks from hackers or unauthorized access.

How to Find the Owner of 104.19.245.19

If you’re curious about who owns a specific IP address like 104.19.245.19, you can use a tool called WHOIS lookup. WHOIS is a public database that provides information about the ownership of domain names and IP addresses.

By entering 104.19.245.19 into a WHOIS lookup tool, you can find out the company or organization that has been assigned that IP address. This can be useful for understanding where traffic is coming from or investigating any unusual network activity.

IP Address Conflicts

Sometimes, two devices on the same network might end up with the same IP address, which causes an IP conflict. When this happens, neither device will be able to connect properly because the network can’t tell them apart.

IP conflicts are more common with private IP addresses inside a local network, but they can happen with public IP addresses too. To fix an IP conflict, you usually need to manually assign a new IP address or restart your router to get a fresh one from your ISP.

How to Protect Your IP Address

Since your public IP address, like 104.19.245.19, is visible on the internet, it’s important to protect it for privacy reasons. Here are a few ways to keep your IP address safe:

1. Use a VPN: A Virtual Private Network (VPN) hides your IP address by routing your internet traffic through a different server. This makes it harder for websites or hackers to track your real IP address.
2. Limit Public Wi-Fi: Public Wi-Fi networks are more vulnerable to hackers. Avoid using them for sensitive tasks, like banking, unless you’re using a VPN.
3. Check for Suspicious Activity: Regularly monitor your network for unusual activity, such as unauthorized devices connecting to your Wi-Fi.
