     5  #### **--mac-address**=*address*
     6  
     7  <<Container|Pod>> network interface MAC address (e.g. 92:d0:c6:0a:29:33)
     8  This option can only be used if the <<container|pod>> is joined to only a single network - i.e., **--network=_network-name_** is used at most once -
     9  and if the <<container|pod>> is not joining another container's network namespace via **--network=container:_id_**.
    10  
    11  Remember that the MAC address in an Ethernet network must be unique.
    12  The IPv6 link-local address is based on the device's MAC address
    13  according to RFC4862.
    14  
    15  To specify multiple static MAC addresses per <<container|pod>>, set multiple networks using the **--network** option with a static MAC address specified for each using the `mac` mode for that option.
