Which of the Following Best Explains How IP Addresses Are Assigned?
Have you ever wondered what makes it possible for devices to connect and talk to each other online? Whether you’re browsing social media, checking emails, or streaming your favorite show—there’s something quietly working in the background: your IP address.
So, which of the following best explains how IP addresses are assigned? Don’t worry—this post breaks it all down in simple terms. You don’t need to be a tech whiz to understand it!
What Is an IP Address, Anyway?
Before we dive into how they’re assigned, let’s make sure we understand what an IP address actually is.
An IP (Internet Protocol) address is like the home address of your device on the internet. Just like the postal service needs your street address to deliver mail, websites and apps need your IP address to send data back to your device.
There are two main types you’ll hear about:
Now that you know what an IP address is, let’s answer the big question: Which of the following best explains how IP addresses are assigned? Read on!
Who’s in Charge of Assigning IP Addresses?
You might think your internet provider just makes one up and gives it to you. But there’s actually a global system in place.
At the top of the ladder is an organization called the Internet Assigned Numbers Authority (IANA). IANA hands out huge blocks of IP addresses to five regional internet registries (RIRs) spread across the globe.
These registries are in charge of distributing addresses to:
So, it’s kind of like IANA is the bakery, and the RIRs are local stores that sell the bread (IP addresses) to customers.
Role of Your ISP (Internet Service Provider)
Here’s where it gets closer to home. Once your internet service provider receives a chunk of IP addresses from a regional registry, it assigns one to your device or router.
There are two types of assignment they might use:
Most homes use dynamic addresses because they’re easier to manage and cost less. But say you want to run a home server—then a static IP might be better.
That brings us back to our original question—which of the following best explains how IP addresses are assigned? The answer is simple when you follow the chain: from IANA to RIRs to ISPs to You.
Private vs. Public IP Addresses: What’s the Difference?
This is a common point of confusion, so let’s clear it up.
Public IP addresses are the ones given to your network by your ISP. They’re visible on the wider internet—kind of like a phone number people use to call you.
Private IP addresses are used just inside your home or business network. These are often automatically set by your router and are not visible outside your network.
Here’s a quick analogy: imagine the public IP as your apartment building’s address, and your private IPs are like your individual apartment numbers.
This system helps conserve IP addresses by allowing many people to share the same public one while keeping their devices separate internally.
How IPv6 Changes the Game
As more devices connect to the internet—from smartphones to smart toasters—the world simply ran out of IPv4 addresses. There just weren’t enough to go around.
Enter IPv6. This newer protocol allows for a nearly unlimited number of unique IP addresses. Seriously—it offers something like 340 undecillion (that’s a 3 followed by 38 zeros!) combinations.
IPv6 was designed to make assigning IP addresses more efficient. Devices can even generate their own unique addresses automatically, which speeds up the process.
Still, IPv4 hasn’t vanished. Many places use both types in what’s called a “dual-stack” system.
Can You Choose Your Own IP Address?
The short answer is: sometimes.
If you’re a typical home user, your ISP usually handles your IP assignment dynamically, and you don’t have much control.
However, if you need to set up a specific network—for example, a home media server or a surveillance system—your router can assign a static local IP address to a device. This helps keep things consistent.
For public static IPs, though, you’d need to arrange that with your ISP. It might cost more and require special setup.
So next time you ask yourself, which of the following best explains how IP addresses are assigned?—remember that some can be chosen, but others are handed down from the top.
The Role of DHCP in Dynamic IP Assignment
Here’s another acronym you’ll want to know: DHCP, or Dynamic Host Configuration Protocol.
This is the technology your router or ISP uses to automatically assign IP addresses within your network. It saves you from having to set addresses manually.
Say your cousin brings over their laptop and connects to your Wi-Fi—DHCP gives their device a temporary IP so it can talk to the internet. Pretty neat, right?
And the best part? When they leave, that IP goes back into the pool to be reused later.
Why IP Assignment Matters More Than You Think
You might not think much about your IP address, but it plays several important roles:
So next time you’re navigating through your network settings or setting up a smart home device, you’ll know how and why that mysterious address was chosen.

Final Thoughts: What’s the Best Explanation?
So, when it comes to answering the key question, which of the following best explains how IP addresses are assigned?—here’s the simplest way to put it:
IP addresses are assigned through a global system that starts with IANA, moves down to regional registries, and finally gets distributed to devices by ISPs or local routers using DHCP.
It’s like a waterfall of addresses—starting from a single source and branching out until every device has what it needs to get online.
Whether you’re watching TV, chatting with friends, or working remotely, it all relies on these invisible numbers working their magic in the background.
