[dns]
=====

Overview DNS section. 

**dns1=x.x.x.x**
  By default is not defined.

  Specifies primary DNS to be sent to peer.

**dns2=x.x.x.x**
  By default is not defined.

  Specifies secondary DNS to be sent to peer.

.. admonition:: Note:

    Params in this section also may be applied with ``accel-cmd reload`` command, but for new connections.

Also *accel-ppp* has very interesting way to allocate DNS addresses which sent RADIUS server. Received RADIUS attributes is more prior than params in config. For *ppp* (pppoe, pptp, l2tp, sstp) connection type used attributes ``MS-Primary-DNS-Server``, ``MS-Secondary-DNS-Server``. For ipoe connection type need send attributes ``DHCP-Domain-Name-Server``
