The router can allocate DNS server addresses after being solicited to the devices
connected to it using PPP, PCs dialed to it for example, allowing these devices to
access the network using their domain names.
If you are connected to the router using a PC, you can execute the winipcfg command
or the ipconfig/all command to view the provided DNS server address.
Related command: ppp authentication-mode pap, ppp ipcp dns admit-any,

secondary DNS address as 100.1.1.2.

Description
Use the ppp ipcp dns admit-any command to enable the router to accept the
unsolicited DNS server address allocated by the peer without sending a DNS request.
When the router is connected using PPP to another device, a network access server of
a service provider for example, this allows the router to use the DNS server allocated
by the peer.
Use the undo ppp ipcp dns admit-any command to disable the router to accept the
unsolicited DNS server address allocated by the peer.
By default, the router does not accept the unsolicited DNS address allocated by the
peer.
Related command: ppp authentication-mode pap, ppp ipcp dns, local-user.
Example
# Enable the router to accept the unsolicited DNS server address allocated by the peer.
