What Does an IP Address Mean: Your Digital Identity

Your IP address is like your digital identity. It’s what identifies your device whenever you connect to the internet or a network.

An IP address is made up of numbers, like It’s assigned to your device by your internet service provider or network administrator. The IP address allows information to be delivered to the correct location.

Public vs. Private IP Addresses

Public IP addresses are used to connect your device to the internet and can be seen by any website or service you access. Private IP addresses are used for devices on a private network, like your home Wi-Fi. They can only be seen by other devices on that network.

Dynamic vs. Static IP Addresses

Most residential internet connections use dynamic IP addresses, which means your IP address can change whenever your router restarts or after a set period of time. Static IP addresses remain the same and are usually used by businesses. If you want to access devices on your home network remotely or host servers, you’ll want a static IP.

Why IP Addresses Matter

Your IP address is crucial for accessing the internet and connecting various devices. However, it can also be used to track your internet activity and location. Using a virtual private network or VPN helps mask your real IP address and hide your online identity.

IP addresses are a fundamental part of how networks and the internet work. Understanding the basics helps you better navigate the digital world and keep your information secure. The more you know about how IP addresses operate, the more power you have over your privacy and connectivity.

IP Address Classes: Public vs Private Addresses

IP addresses come in two main types: public and private. Public IP addresses are used to connect your network to the internet, while private IP addresses are used within a private network.

Public IP Addresses

Public IP addresses are assigned by your internet service provider (ISP) and are used by devices – like your router – to connect to the internet. They allow you to access websites, send emails, stream media and basically do anything on the internet.

These addresses are either IPv4 (the older standard, like or the newer IPv6 (like 2001:db8:85a3::8a2e:370:7334). IPv6 was created to solve the problem of IPv4 address exhaustion. ISPs charge for public IP addresses, so most homes and small businesses only have a single public IP address that connects their network to the internet.

Private IP Addresses

Private IP addresses are used inside a private network and are not routable on the public internet. This means they provide an extra layer of security since the outside world cannot directly access devices with private IP addresses. The most common ranges are:

  • – (10/8 prefix)
  • – (172.16/12 prefix)
  • – (192.168/16 prefix)

Private IP addresses allow you to connect multiple devices within your network, like printers, security cameras, smartphones, tablets, PCs, and more. They provide an efficient way to manage, secure, and access your various networked devices.

Static vs Dynamic IP Addresses: What’s the Difference?

Static vs Dynamic IP Addresses: What’s the Difference?

Every device connected to the Internet is assigned an IP address to identify its location. There are two main types of IP addresses: static and dynamic.

Static IP Addresses

A static IP address is a fixed address that does not change. It is manually configured by a network administrator to a specific device. Static IP addresses are preferable for network devices like printers, servers, and routers since their IP addresses rarely need to change. They also allow for easy access since the IP address always remains the same. However, static IP addresses require manual configuration and can be challenging to setup for home networks. They are best suited for business networks.

Dynamic IP Addresses

In contrast, a dynamic IP address is automatically assigned to a device by a router or network and can change over time. Most home networks use dynamic IP addressing since it requires no manual configuration and the IP addresses are assigned as needed from a pool of available addresses. However, the changing nature of dynamic IP addresses means that a device’s IP address may be different each time it connects to the network. This can make accessing the device remotely more difficult.

For home networks, dynamic IP addressing is typically the easiest approach. However, for certain devices like security cameras, media servers or voice over IP phones, using a static IP address is recommended for reliable access. Some routers allow you to reserve an IP address for a specific device so that it is always the same each time that device connects to the network. This provides the benefits of a static IP address without the manual configuration.

Whether you choose static or dynamic IP addressing for your network depends on your needs and technical expertise. For simple plug-and-play connectivity, dynamic is the way to go. For more control and access, static IP addresses are the preferred option. The good news is, with some routers, you can enjoy the best of both worlds.

IPv4 vs IPv6: Why We Needed an IP Address Upgrade

IPv4, or Internet Protocol version 4, has been used to assign IP addresses to devices since the early days of the internet. However, with more and more internet-connected devices in use, the 4.3 billion unique addresses available under IPv4 were nearly depleted. This is where IPv6 comes in.

IPv6, or Internet Protocol version 6, was developed to replace IPv4. It uses 128-bit addresses instead of the 32-bit addresses of IPv4, providing over 340 undecillion (3.4×10^38) unique addresses. Think about how many IP addresses that could provide for the huge number of smartphones, tablets, smart home devices, and other internet-connected gadgets.

Some of the main differences between IPv4 and IPv6 are:

•Address Space: As mentioned, IPv6 provides an enormous number of IP addresses compared to IPv4. This huge increase in address space is one of the driving forces behind the transition to IPv6.

•Address Representation: IPv4 addresses are represented as four decimal numbers separated by periods, like IPv6 addresses use eight groups of four hexadecimal digits separated by colons, like 2001:0db8:85a3:0000:0000:8a2e:0370:7334.

•Header Format: The IPv6 header has a simpler format that can provide more flexibility and features. The IPv4 header contains 12 fields, while the IPv6 header contains only 8 fields.

•Transition Technologies: Technologies like 6to4 tunnels, NAT64, and dual-stack routers help transition networks from IPv4 to IPv6. They allow IPv4 and IPv6 to co-exist together on the same network.

•Security: IPv6 has built-in security features like IPSec that were optional add-ons for IPv4. IPv6 is also less prone to some attacks that worked on IPv4 networks.

The transition to IPv6 has been gradual, but it’s key to support the growth of the internet and enable advanced new technologies. While IPv4 and IPv6 will co-exist for years to come, IPv6 is the future of IP addressing.

How to Find Your IP Address
