IP Address Converter

IPOK dev tools provide fast network diagnostics and data conversions, including IP purity, subnet risk, DNSBL blacklist, and ASN routing lookups.

Convert an IP between dotted decimal, decimal integer, hex and binary — common when writing firewall rules, matching logs, or storing IPs in a database (many systems store them as integers). Dotted or decimal input is auto-detected.

For IPv6 it shows the full expanded form, the canonical compressed form (::) and the 128-bit integer, handy for verifying configs. All conversion is local, never uploaded.

Converted locally, never uploaded. Turning an IP into decimal / hex is common in firewall rules, log matching and DB storage; IPv6 expand / compress helps verify configs.

FAQ

What is 192.168.1.1 in decimal?

3232235777, from 192×256³ + 168×256² + 1×256 + 1. Paste a dotted IP to auto-compute decimal / hex / binary.

Why are IPs stored as long numbers in databases?

Many systems store IPv4 as a 32-bit unsigned integer (compact, easy to compare / sort). This tool converts between the integer and dotted forms.

What does :: mean in IPv6?

:: stands in for one run of all-zero groups (it may appear only once in an address). This tool shows both the expanded and compressed forms.
