show this help message and exit

-4 INTEGER, --ipv4mask INTEGER

truncate the last n bits (default: 12)

-6 INTEGER, --ipv6mask INTEGER

truncate the last n bits (default: 84)

-i INTEGER, --increment INTEGER

increment the IP address by n (default: 0)

-o FILE, --output FILE

file to write to

--input FILE

File or FIFO to read from (default: stdin)

-c INTEGER [INTEGER ...], --column INTEGER [INTEGER ...]

assume IP address is in column n (1-based indexed; default: 1)

-l STRING, --delimiter STRING

log delimiter (default: " ")

--regex STRING [STRING ...]

regex for detecting IP addresses (use optionally instead of -c)

-r STRING, --replace STRING

replacement string in case address parsing fails (Example: 0.0.0.0)
