    Explaining the supported values for that server config option about which interfaces and ports to listen on, or that bot config option about which servers to connect to.

    • Listen on a single port on localhost: Just put the number.

      • If types are a concern, supply any integer or a digit-only string.
    • Listen on any/all interfaces: *: + port number(s).

      • Specifies that you don't care about interfaces. Usually that results in listening on all available interfaces.
      • For multiple port numbers, see below.
    • For multiple values, separate them with at least one space.

      • You can safely put one comma before the spaces if you like to, or even between them. Spaces are any combination of " \t\r\n" = U+0020 space, U+0009 horizontal tab, U+000D carriage return and U+000A line feed.
    • Don't listen at all: - (Just put a hyphen-minus.)

      • Might be useful on servers that have additinal other means of interaction.
      • When encountered in a multi-value list, ignore the remaining values.
    • Listen on specific interface and ports: Put the interface (as hostname, IP.v4.addr.ess, [IP:v6:addr:ess] or *), a colon (:) and the port(s).

      • Separate multiple ports with comma (,), no spaces. Any space would separate the port from the interface, so it will be parsed as just a port number, as described above.
      • To include all ports of the previous address value, put a single _ U+005F low line) as the first port number.
      • To temporarily exclude (disable) a port number, put a single _ (U+005F low line) directly after it.

    JavaScript Parser

    An ipaddrportslist parser in JavaScript (ECMAScript) is provided in parser.js. For detailed examples see the test specs. Basic example:

    var net = require('net'), ipAddrPortsList = require('ipaddrportslist'),
      listenAddrs = ipAddrPortsList(process.env.HELLOPORT || 2002);
    listenAddrs.forEach(function listenOnAddr(lsnAddr) {
      var srv = net.createServer(), descr;
      /* ... handlers setup ... */
