  <p>
   The MySQL server listens on one or more network sockets for
        TCP/IP connections. Each socket is bound to one address, but it
        is possible for an address to map onto multiple network
        interfaces.

   Set the
   <a class="link" href="server-system-variables.html#sysvar_bind_address">
    <code class="literal">
     bind_address
    </code>
   </a>
   system
        variable at server startup to specify the TCP/IP connections
        that a server instance accepts. You can specify multiple values
        for this option, including any combination of IPv6 addresses,
        IPv4 addresses, and host names that resolve to IPv6 or IPv4
        addresses. Alternatively, you can specify one of the wildcard
        address formats that permit listening on multiple network
        interfaces. A value of *, which is the default, or a value of
   <code class="literal">
    ::
   </code>
   , permit both IPv4 and IPv6 connections on
        all server host IPv4 and IPv6 interfaces. For more information,
        see the
