Sockaddr is a command-line utility that makes it easy to query network address information from the local server. With sockaddr it is possible to create a list of the RFC 1918 addresses on a server, obtain the default gateway, or public IP addresses and use this information in other shell scripts. See the website for additional templating and IP math functions. WWW: https://github.com/hashicorp/go-sockaddr/tree/master/cmd/sockaddr
