About IP Address Lookup

The IP Address Lookup tool lets you detect your own public IP address instantly and perform a detailed analysis of any IPv4 or IPv6 address — all in your browser with no sign-up required.

Click Detect My IP to retrieve your current public IP address along with approximate geolocation metadata such as city, region, country, ISP, and timezone. Or paste any IP address into the analyser to see a full breakdown: address type (public, private, loopback, link-local, multicast), octet or group breakdown, 32-bit or 128-bit binary representation, hexadecimal encoding, and decimal value for IPv4.

For IPv6 addresses, the tool shows both the full expanded form and the compressed notation using :: for consecutive zero groups, along with the address scope (global unicast, link-local, unique local, loopback, multicast, 6to4, or NAT64).

This tool implements IP address parsing logic following the ip-address specification, covering all standard IPv4 classes and IPv6 address types as defined in RFC 1918, RFC 4291, and related standards.

Ideal for network debugging, learning about IP address structure, verifying VPN or proxy configuration, and quickly checking whether an address is public or private.

How to Use IP Address Lookup

  1. Click 'Detect My IP' to instantly find your current public IP address and location info.

  2. Or type any IPv4 (e.g. 192.168.1.1) or IPv6 (e.g. 2001:db8::1) address into the analyser field.

  3. See a full breakdown: address type, binary, hex, and decimal representations.

  4. Click Copy next to any field to copy that value to your clipboard.

Frequently Asked Questions

What is my public IP address?

Your public IP is the address assigned to your internet connection by your ISP. Click 'Detect My IP' in this tool to see it. It may differ from your local/private IP used inside your home or office network.

What is the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses written in four decimal octets (e.g. 192.168.1.1) and supports about 4.3 billion addresses. IPv6 uses 128-bit addresses in hexadecimal (e.g. 2001:db8::1) and supports a practically unlimited number, solving the IPv4 exhaustion problem.

What are private IP addresses?

Private (RFC 1918) IPs are reserved for local networks: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. They are not routable on the public internet — your router uses NAT to translate them to your public IP.

What does the binary representation show?

The binary form shows exactly which bits are set in the address. For IPv4, each of the four octets becomes 8 bits. This is useful for understanding subnet masks, CIDR notation, and how routers match IP prefixes.

Is my IP address stored when I use Detect My IP?

No — this tool calls a public IP detection API in your browser to return your IP, but Toolgin does not log or store it. Only the IP info API provider briefly sees your request.
