IP Address Info
Enter an IPv4 address to classify it and see its integer, hex, and binary forms.
Understand any IPv4 address
An IP address carries more information than four numbers — its range tells you whether it is public, private, or reserved, and its bit pattern matters for masks and routing. Enter an address and this classifies it and shows its numeric forms.
172.16.5.4, for instance, is a private Class B address (inside 172.16.0.0/12), equal to the integer 2,886,730,500 and 0xAC100504 in hex. Loopback, link-local, and multicast ranges are flagged too.
Offline and private
This is a self-contained analysis of the address, not a server geolocation lookup, so it works offline and nothing you enter leaves your browser.
Frequently Asked Questions
What does it tell me about an IP?
Its historical class (A–E), whether it is private, loopback, link-local, or reserved, and its value as a 32-bit integer, in hexadecimal, and in binary.
What counts as a private address?
The ranges 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16, which are not routable on the public internet.
Is this a geolocation lookup?
No — geolocation needs a server database. This is a pure, offline analysis of the address itself, with nothing uploaded.
