About

Inspired by go-discover, go-netaddrs is a Go (golang) library and command line tool to discover ip addresses of nodes in a customizable fashion suitable for any environment. It returns IP addresses (IPv4 or IPv6) given a

1. DNS name, OR
2. custom executable with optional args which (refer to examples under the folder sample_scripts/):
   • on success - exits with 0 and prints whitespace delimited IP (v4/v6) addresses to stdout.
   • on failure - exits with a non-zero code and optionally prints an error message of up to 1024 bytes to stderr.
