What Is an IP Address? Understanding Internet Protocol Addresses

Basic Definition

An IP address (Internet Protocol Address) is a unique string of numbers assigned to each device connected to the internet. Just like your home address helps the postal service deliver mail to the right place, checkip.tech helps devices on the internet find and communicate with each other.

Types of IP Addresses

Public IP vs Private IP:

  • Public IP: A publicly accessible address assigned by your ISP, reachable from anywhere on the internet
  • Private IP: An internal address used only within your local network (LAN)

Static IP vs Dynamic IP:

  • Static IP: A fixed address that doesn’t change over time
  • Dynamic IP: An address that can change when you restart your router or according to ISP cycles

IPv4 vs IPv6: Understanding the Key Differences

IPv4 – The Legacy Standard Still Dominating

IPv4 address lookup still handles the majority of internet traffic today. IPv4 uses a 32-bit format, allowing for approximately 4.3 billion unique addresses. A typical IPv4 address looks like: 192.168.1.1

IPv4 Characteristics:

  • Format: 4 groups of numbers from 0-255, separated by dots
  • Total addresses: 2³² ≈ 4.3 billion addresses
  • Problem: Address exhaustion due to explosive growth of internet-connected devices

IPv6 – The Future of Internet Addressing

IPv6 address was developed to solve IPv4’s address exhaustion problem. With a 128-bit format, IPv6 provides 2¹²⁸ addresses – an enormous number sufficient for all future devices.

IPv6 Advantages:

  • Massive address space: 340 undecillion addresses
  • Better built-in security with IPSec
  • More efficient routing
  • Automatic address configuration

IPv6 Format: 2001:0db8:85a3:0000:0000:8a2e:0370:7334

Yes, most ISPs use dynamic IP addressing, meaning your IP address can change when you restart your router or according to scheduled cycles. Only static IP services maintain the same address permanently.

2. Can you find someone’s exact home address from their IP?

No, IP addresses can only determine approximate location within a 25-40km radius. Exact addresses require legal processes and ISP cooperation.

3. Does using a VPN affect IP lookup results?

Yes, when using a VPN, ip lookup tools will show the VPN server’s information instead of your actual location. This is the primary purpose of VPN services.

4. Why does my ip location show the wrong city?

This can happen because your ISP’s headquarters is in a different city, or you’re using mobile internet with towers in another area.

5. Is IPv6 more secure than IPv4?

Yes, IPv6 was designed with better built-in security, including mandatory IPSec support and resistance to certain attacks that affect IPv4.

6. How can I check if I’m using IPv4 or IPv6?

Use online IP lookup tools that display both IPv4 and IPv6 addresses. IPv4 has 4 number groups, IPv6 has 8 alphanumeric groups.

7. Is it legal to look up someone else’s IP address?

Looking up publicly available IP information is legal. However, using this information for harassment, illegal tracking, or privacy violations is illegal.

8. Why do I need multiple ip checker tools?

Different tools use different databases and may provide additional information like proxy detection, security status, or more detailed ISP information.

9. Can whats my ip results be faked?

The actual IP address cannot be faked, but it can be hidden through VPN, proxy, or Tor. Proxy detection tools can identify when this is happening.

10. How can I improve my online privacy?

Use reputable VPN services, avoid sharing unnecessary personal information, use private browsing modes, and regularly check IP lookup to ensure privacy tools are working correctly.

11. What’s the difference between IP lookup and IP tracking?

IP lookup retrieves publicly available information about an IP address, while IP tracking involves monitoring IP activity over time, which may have legal and privacy implications.

12. How accurate is ip address location for mobile devices?

Mobile IP geolocation is generally less accurate due to carrier networks, NAT, and tower locations. Accuracy can vary from 5-50km depending on the carrier and location.

13. Can businesses block specific IP addresses?

Yes, businesses commonly use ip location data to block traffic from certain countries or regions for compliance, security, or business reasons.

14. What is the relationship between DNS and IP addresses?

DNS (Domain Name System) translates human-readable domain names into IP addresses. When you visit a website, DNS lookup reveals the ip address of the server hosting that site.

15. How do streaming services detect VPN usage?

Streaming platforms use advanced ip checker systems that identify VPN servers, proxy networks, and known VPN IP ranges to enforce geographic restrictions.
