(Optional) Configuring IPv6 DNS Spoofing
Context
If the device is enabled with IPv6 DNS proxy or relay but is not configured with a DNS server address or has no route to the DNS server, the device does not forward or respond to DNS query messages from DNS clients. If IPv6 DNS spoofing is enabled, the device uses the configured IPv6 address to respond to all DNS query messages.
In addition to enabling IPv6 DNS proxy or relay, one of the following
requirements must be met to make IPv6 DNS spoofing take effect:
- No DNS server is configured.
- A DNS server is configured, but dynamic DNS resolution is disabled.
- No route is reachable to the DNS server.
- No source IPv6 address is available for the outbound interface connected to the DNS server.
If one of the preceding requirements is met, when receiving an AAAA or A6 query, the IPv6 DNS proxy or relay return spoofing reply messages using the configured IPv6 address.
