IPv4 converter
ClientEnter dotted decimal, decimal integer, hex, or binary—see every form at once. For prefixes use CIDR calculator.
About IPv4 converter
Convert IPv4 between dotted decimal, 32-bit integer, hex, and binary—client-side quick reference. The interactive transform on this page runs in your browser tab—Toolcore does not need your paste for the core operation described above.
How to use this page
Paste or type in the main workspace, run the primary action from the toolbar, then copy or download the result. Use Load example when the page offers it, or URL prefill (?q= / ?qb=) so agents and tickets open the same input.
Convert among dotted decimal, 32-bit integer, hex, and binary. See also CIDR calculator.

Nearby workflows on Toolcore
- IPv4 subnet table — Split a parent IPv4 CIDR into equal child prefixes: every subnet listed with network, broadcast, and host bounds—capped list, local only. when headers, identifiers, or reference tables need a sibling check.
- IPv6 expand & compress — Single IPv6 address: full 8-group expanded and RFC 5952 compressed text—::ffff:IPv4 mapped, not CIDR math—local only. when headers, identifiers, or reference tables need a sibling check.
- Hex encode & decode — UTF-8 text to hex and hex to text—strip spaces, local only. when headers, identifiers, or reference tables need a sibling check.
Common use cases
- Translate ACL numeric hosts to dotted form.
- Check integer IP values from logs or databases.
- Study bitwise layout before CIDR math.
Common mistakes to avoid
Using signed 32-bit integers
Decimal form here is unsigned 0–4294967295.
Subnet sizing
Use the CIDR calculator for prefix, mask, and host ranges.
FAQ
IPv6?
Use IPv6 expand and compress for v6 text forms.
Binary without dots?
Paste up to 32 bits with or without dot separators.
