Default level

2: System level

Parameters

ip-address: Specifies the IP address used to spoof name query requests.

Description

Use dns spoofing to enable DNS spoofing.

Use undo dns spoofing to disable DNS spoofing.

By default, DNS spoofing is disabled.

With DNS proxy enabled but no DNS server specified or no DNS server reachable, a device cannot forward a DNS request, or answer the request. In this case, you can enable DNS spoofing on the device to spoof a reply with the configured IP address. Once a DNS server is reachable, the device will send DNS requests to the server and return replies to the requesting DNS clients.

If you repeatedly execute the dns spoofing command with different IP addresses specified, the latest configuration will overwrite the previous one.

Examples

# Enable DNS spoofing and specify the IP address as 1.1.1.1.

[Sysname] dns spoofing 1.1.1.1
