+MacAddress
+==========
+
+.. versionadded:: 7.1
+
+    The ``MacAddress`` constraint was introduced in Symfony 7.1.
+
+This constraint ensures that the given value is a valid MAC address (internally it
+uses the ``FILTER_VALIDATE_MAC`` option of the :phpfunction:`filter_var` PHP
+function).
+
+==========  =====================================================================
+Applies to  :ref:`property or method <validation-property-target>`
+Class       :class:`Symfony\\Component\\Validator\\Constraints\\MacAddress`
+Validator   :class:`Symfony\\Component\\Validator\\Constraints\\MacAddressValidator`
+==========  =====================================================================
+
+Basic Usage
+-----------
+
+To use the MacAddress validator, apply it to a property on an object that
+will contain a host name.
