IP Address Info: Analyze and Validate Any IP Address

Every device on the internet has an IP address. Our free IP Address Info tool analyzes any IPv4 or IPv6 address entirely in your browser — no data is sent to external servers. Get instant format validation, public/private classification, binary representation, and subnet reference.

IPv4 vs IPv6

IPv4 uses 32-bit addresses written as four decimal numbers separated by dots (e.g., 192.168.1.1). With about 4.3 billion possible addresses, IPv4 space has been exhausted.

IPv6 uses 128-bit addresses written in hexadecimal groups separated by colons (e.g., 2001:0db8::1). This provides roughly 340 undecillion addresses — enough for the foreseeable future.

How to Use the Tool

1. Enter any IP address in the input field
2. Click Analyze or use an example address
3. View the results: IP version, type (public/private), class, binary form, and decimal value
4. For IPv4, see a common subnet reference table

Understanding IP Classes

IPv4 addresses are divided into classes based on the first octet:

Class	Range	Default Subnet	Purpose
A	1-127	255.0.0.0	Large networks
B	128-191	255.255.0.0	Medium networks
C	192-223	255.255.255.0	Small networks
D	224-239	N/A	Multicast
E	240-255	N/A	Reserved

Private vs Public IPs

Private IP ranges (not routable on the internet): 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16. These are used within local networks. Public IPs are globally unique and routable.

Frequently Asked Questions

Does this tool look up my current IP? No. This tool analyzes whatever IP address you enter. It performs local format analysis only.

Can I check IPv6 addresses? Yes. Enter any valid IPv6 address including compressed forms like ::1.
