rldw

regex long, didn't write

A command-line utility used primarily to quickly strip IPv4 and IPv6 addresses from standard input. This is handy for rapidly pulling data out of log files for further processing, without having to paste in complicated regular expressions.

Commands

  • parse IPv4 and IPv6 addresses from stdin (rldw parse)
  • generate random publicly routeable IPv4 and IPv6 addresses (rldw generate)

Written in Go utilizing:

rldw parse examples

❗ rldw parse defaults with --ipv4 to true, in order to parse for ipv6 addresses you must use either rldw parse -4=false -6 or rldw parse--ipv4=false --ipv6

Parse nft sets for IPv4 addresses

$ nft list set inet filter scanners | rldw parse -4

45.76.146.20
45.148.10.81

Parse journalctl logs for IPv4 addresses and print stats

$ journalctl -n 5 --no-pager | rldw parse -4 -s

Parse ip addr output for IPv6 addresses

⚡ IPv6 address support is not perfect, use at your own risk 
ip addr | rldw parse -6 -4=false

Generate random IPv4 and IPv6 addresses

rldw generate can be used to generate random publicly routeable IPv4 and IPv6 addresses. This can be handy for generating unit test datasets.

IPv4: Generate 5 random IPv4 addresses

$ rldw generate -4 -c 5
62.150.113.112
176.59.94.136
105.238.3.48
98.55.211.53
144.35.170.232

IPv6: Generate 5 random IPv6 addresses

$ rldw generate -4=false -6 -c 5
