Every device connected to the internet has an IP address, a digital identifier that enables the internet to know where to send information. Your public IP address is like your digital “home address” on the web. It identifies your connection to the wider internet, whether you’re hosting a website, sending an email, or simply browsing the web.
Keep in mind that this is different to your Server IP Address, which is a unique identifier that allows devices to connect over a network. It can be either public (used to communicate over the internet) or private (used within a local network).
This guide will help you answer the question, “What is my Public IP Address?”, and we’ll give you some guidance on how to find it so that you can stay informed, secure, and in control of your online presence.
What Is a Public IP Address and Why Does It Matter?
A public IP address is assigned by your Internet Service Provider (ISP) and identifies your network on the global internet. It’s essential for activities like:
- Hosting websites or email servers
- Remote access to your network or device
- Online gaming and peer-to-peer connections
- Troubleshooting email deliverability (e.g., MailChannels or DNS issues)
Think of it as the way other computers “find” you, whether it’s a customer visiting your website or a remote connection request.
Public vs Private IP Addresses
| Type | Purpose | Who Assigns It | Where It’s Used |
| Public IP | Identifies your device/network on the internet | ISP | Internet-facing services like websites, emails, remote access |
| Private IP | Identifies devices inside your local network (like printers, phones, or laptops) | Router/DHCP | Home or business LAN (Local Area Network) |
TIP: Private IPs keep your local devices connected internally, while your public IP connects your entire network to the internet.
