IP Address Information Tool
IP Address Information Tool inspect ipv4 address ip decimal and binary private address checker convert ipv4 to binary dotted decimal to integer hex ip address converterInspect or convert one IPv4 value without a lookup
Select dotted decimal, unsigned integer, hexadecimal, or 32-bit binary input. The page converts the value into every supported form and identifies its well-known special-use range from the resulting address.
Four views of the same 32 bits
An IPv4 address contains 32 bits divided into four octets. Dotted decimal writes each octet from 0 through 255. Unsigned integer treats all 32 bits as one value from 0 through 4,294,967,295. Hexadecimal uses up to eight base-16 digits, while binary uses exactly 32 zeros and ones.
Accepted input
Dotted decimal requires four canonical base-10 octets. Integer input accepts decimal digits inside the unsigned 32-bit range. Hexadecimal accepts one through eight digits after an optional 0x prefix. Binary accepts exactly 32 bits after spaces are removed. Values outside those boundaries are rejected rather than wrapped.
Range information
Membership in fixed ranges can be calculated locally after any format is converted. The page recognizes private, loopback, link-local, shared, documentation, benchmarking, multicast, reserved, and other public-use address space. It makes no claim that an address is assigned, routed, reachable, or safe.
Worked example
For 192.168.1.25, the category is private-use because it falls inside 192.168.0.0/16. Its unsigned integer is 3232235801, hexadecimal form is 0xC0A80119, binary is 11000000 10101000 00000001 00011001, and reverse-DNS notation is 25.1.168.192.in-addr.arpa. Entering any of those first four forms returns the same result.
Representation does not change meaning
Conversion only rewrites bits. Private addresses are reused inside many unrelated networks and are not routed as public Internet destinations. A public-use label does not identify an owner or prove global routing. Some software rejects non-dotted forms even when they encode the same value, so use the format required by the receiving system.
Limitations and privacy
The entered value stays in this browser. No public-IP discovery, WHOIS, regional registry, ISP, organization, geolocation, reputation, reverse-DNS query, port scan, or reachability test occurs. IPv6, CIDR prefixes, and subnet calculations remain outside this page's scope. Special-use assignments can evolve; consult the IANA IPv4 Special-Purpose Address Registry for authoritative operational work.
IP Address FAQ
Does this reveal my current IP?
No. It analyzes only the IPv4 value you enter.
Can binary input contain spaces?
Yes. Spaces are ignored, but exactly 32 binary digits must remain.
Does reverse notation perform DNS?
No. It formats the query name only and makes no network request.
