About:
The need for this module came when I wanted to prevent commerce recurring
transactions from happening on production envorionments. By comparing
the $_SERVER['SERVER_ADDR'] address in a condition, I'm able to prevent this
on all other installations of the project.

Instructions:
Install module and add exposed rules condition to any rule.
Note: If running these rules via cron, the variables may not be available if use CLI or Drush based crons.

Example Rules condition component to check if site is "production"

{ "rules_site_is_running_on_production_server" : {
    "LABEL" : "Site is running on production server",
    "PLUGIN" : "and",
    "REQUIRES" : [ "rules_server_variables" ],
    "AND" : [
      { "rules_server_variables_compare" : {
          "variable" : "SERVER_ADDR",
          "value" : " [LAN IP OF SERVER]",
          "operator" : "equal_to"
        }
      },
      { "rules_server_variables_compare" : {
          "variable" : "SERVER_NAME",
          "value" : "[FQDN/DOMAIN NAME]",
          "operator" : "equal_to"
        }
      }
    ]
  }
}
