Convert any decimal number back to its IPv4 or IPv6 address.
Enter a decimal number to convert it back to an IP address. Values up to 4,294,967,295 are converted to IPv4, and larger values up to 128-bit are converted to IPv6. This is useful when working with IP addresses stored as integers in databases or log files.
IP addresses are often stored as plain integers in databases for efficient storage and fast range lookups. An IPv4 address is a 32-bit number, so it fits in a single integer up to 4,294,967,295. IPv6 addresses are 128-bit numbers, producing decimal values up to 39 digits long.
Converting from decimal back to the dotted or colon-separated format is useful when reading raw database records, debugging network logs, or verifying IP range calculations. This tool handles both IPv4 and IPv6 ranges automatically based on the size of the input value.
