GeoIP2 CSV Format Converter

This is a simple utility for converting the MaxMind GeoIP2 and GeoLite2 CSVs to different formats for representing IP addresses such as IP ranges or integer ranges.

Compiled binaries for Linux/x86_64, Windows, and macOS (darwin) can be downloaded from the GitHub releases page.

Usage

Required:

• -block-file=[FILENAME] - The name of the block CSV file to use as input.
• -output-file=[FILENAME] - The file name to the output CSV

In addition, at least one of these is required:

• -include-cidr - Include the network in CIDR format
• -include-range - Include the IP range of the network in string format
• -include-integer-range - Include the IP range of the network in integer format
• -include-hex-range - Include the IP range of the network in hexadecimal format

Output

CIDR (-include-cidr)

This will include the network in CIDR notation in the network column as it is in the original CSV.

Range (-include-range)

This adds network_start_ip and network_last_ip columns. These are string representations of the first and last IP address in the network.

Integer Range (-include-integer-range)

This adds network_start_integer and network_last_integer columns. These are integer representations of the first and last IP address in the network.

Hex Range (-include-hex-range)

This adds network_start_hex and network_last_hex columns. These are hexadecimal representations of the first and last IP address in the network.
