What Is an IP Address?
An IP (Internet Protocol) address is a unique string of numbers separated by periods (IPv4) or colons (IPv6) that identifies each computer using the Internet Protocol to communicate over a network.
Why Do I Need to Know My IP Address?
Knowing your IP address is useful for:
- Troubleshooting network issues: IT support often asks for your IP address
- Remote access: Setting up remote desktop or server connections
- Gaming: Hosting game servers or connecting to specific servers
- Security: Checking if your VPN is working properly
- Website access: Some sites restrict access based on IP location
Is My VPN Working?
If you're using a VPN, your IP address should be different from your regular internet connection. Check these indicators to verify your VPN is active:
- Your IP location doesn't match your physical location
- The ISP name shows your VPN provider, not your internet provider
- The IP type shows as "Datacenter" rather than "Residential"
Types of IP Addresses
IPv4 Address
The most common type, consisting of four numbers between 0-255 separated by dots (e.g., 192.168.1.1). There are about 4.3 billion possible IPv4 addresses.
IPv6 Address
The newer format using hexadecimal numbers separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv6 allows for vastly more addresses.
Public vs Private IP Addresses
Public IP: This is what we show you - it's your address on the global internet, assigned by your ISP. Every device on the internet needs a unique public IP.
Private IP: Used within your local network (like 192.168.x.x or 10.x.x.x). Your router assigns these to devices in your home or office.
Can My IP Address Change?
Yes! Most home internet connections have dynamic IP addresses that can change:
- When you restart your router
- After a power outage
- Periodically as assigned by your ISP
- When you connect from different locations
IP Address Privacy
Your IP address reveals general location information (usually city-level) but not your exact address. To enhance privacy:
- Use a VPN to mask your real IP
- Use Tor browser for anonymous browsing
- Be cautious about sharing your IP address
VPN and Your IP Address
When you connect to a VPN, your real IP address is hidden and replaced with the VPN server's IP. This provides several benefits:
- Privacy Protection: Your ISP can't see your browsing activity
- Location Masking: Appear to be browsing from a different location
- Security: Encrypted connection protects your data
- Access Control: Bypass geographic restrictions
