IP Address Info
Analyze IPv4 and IPv6 addresses to inspect IP versions, scope classifications, octets, and alternative format representations.
Run tool
This online IP address lookup tool analyzes any standard IPv4 or IPv6 string and breaks down its core technical properties. When you supply an address, the utility immediately identifies the IP version and evaluates standard address classifications, including whether the address is private, loopback, link-local, multicast, globally routable, unspecified, or reserved. In addition to structural categorization, the tool provides several parsed format representations. You can view the normalized IP string, the reverse DNS pointer format, and equivalent hexadecimal and binary representations. For IPv4 addresses, the interface also separates and displays the four distinct numeric octets. For IPv6 addresses, the binary field displays as not applicable while maintaining full hexadecimal and normalized formatting. If you leave the input blank, the tool automatically evaluates the default address 8.8.8.8. If an unrecognizable or malformed address string is entered, an error notice appears directly in the results panel.
Instructions
- Enter an IPv4 or IPv6 address into the Address field, or leave it blank to inspect the default address.
- Click the run button to parse and analyze the network address.
- Review the identified IP version, scope classifications, and converted address formats in the result panel.
Examples
- Input: 192.168.1.1: Identifies the input as an IPv4 address, marks it as private, separates octets into 192, 168, 1, and 1, and calculates hexadecimal, binary, and reverse DNS pointer representations.
- Input: 2001:db8::1: Identifies the input as an IPv6 address, displays the normalized expansion, outputs the reverse DNS pointer format, sets binary representation to N/A, and reports relevant scope classifications.
FAQ
Does this tool perform live DNS queries or check host reachability?
No. The tool parses address structure and constructs standard reverse DNS pointer strings locally from the input format. It does not perform active network requests, ping checks, or live DNS lookups.
What happens if I leave the Address input field empty?
When no address is entered, the tool automatically evaluates the default address 8.8.8.8 and returns its standard classifications and format representations.
Can I inspect both IPv4 and IPv6 addresses?
Yes. The tool supports standard IPv4 and IPv6 text strings, providing relevant scope classifications and format representations for either protocol version.
Why does the binary output show N/A for IPv6 addresses?
The binary representation is provided specifically for 32-bit IPv4 addresses. For 128-bit IPv6 addresses, the tool outputs N/A while continuing to provide complete hexadecimal and normalized representations.
