12/28/2023 0 Comments Irip serial numberNAT is a technology that solves this problem by allowing a single IP address to be shared amongst multiple devices. This sounds like a huge number until you realize more than 6 billion devices are connected to the internet, which means not every device gets its own IP address. Slightly more than 4 billion IPv4 addresses currently exist. What is NAT?Īctually means: A technology that allows a single IP address to be shared Instead, we access websites by typing in a URL (like Then, DNS servers translate that URL into an IP address, which your laptop uses to communicate to that specific website. But typing in a numerical IP address every time we wanted to surf the web would be pretty tedious. Websites, which are “virtual machines,” also have IP addresses used to send data to and from the internet. What is DNS?Īctually Means: The internet version of a phonebook ![]() In most cases, your wireless router provides DHCP for the devices on your network. We already explained why devices need IP Addresses to connect to a network, but where do these addresses come from? They’re assigned to devices on your LAN (network) by the DHCP server - very similar to how local governments determine street names and individual street addresses within a community or city. Stands for: Dynamic Host Configuration ProtocolĪctually means: A device that assigns IP addresses How to find the MAC address on an iPhone What is DHCP? You’ll typically need your MAC address when adding a new device to a network, or when restricting a device’s access to a network, and you’ll find it on the device’s label or in its settings. Similar to how your Social Security number allows you to identify yourself and receive government services, a MAC address identifies a device on the network and allows it to receive an IP Address. You can think of a MAC address like your Social Security number. The address is typically a globally unique and alpha numeric code - like the below example of 1A:2B:C3:44:5D:FG for an iPhone. Networking devices are assigned a MAC address during manufacturing to identify the device. What is a MAC Address?Īctually means: Your device’s unique serial number You can locate your IP address in your device’s WiFi settings (or, you can look it up in the eero app). IPv4 is the most common, while IPv6 is a newer standard. There are two types of IP Address: IPv4 and IPv6. Moving networks is like moving cities, which means your device’s IP address typically changes whenever you connect to a different network. Any “machine” connected to the internet - including servers, websites, routers, computers, phones, and more - is assigned an IP address representing its virtual “location” within the respective network. ![]() But instead of mailing addresses, networking devices use IP addresses. Likewise, every device on a network needs a way to know how to send data back and forth. You’ll need her mailing address so the mail carrier knows where to deliver it. Imagine you want to mail a birthday card to your grandma. What is an IP Address?Īctually means: A device’s “location” on a network But how does it work so seamlessly? Let’s break down some of the basics, so the next time the Geek Squad asks for your IP address, you’ll be able to give them a number instead of a blank stare. It provides us with limitless knowledge, endless entertainment, and Amazon Prime. ![]() We love the internet as much as Oprah loves bread.
