Parameters
ip-address: Specifies the IP address used to spoof name query requests.
Description
Use the dns spoofing command to enable DNS spoofing.
Use the undo dns spoofing command 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 switch cannot
forward a DNS request, or answer the request. In this case, you can enable DNS spoofing on the switch
to spoof a reply with the configured IP address. Once a DNS server is reachable, the switch 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> system-view
[Sysname] dns spoofing 1.1.1.1
