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