Usage Guidelines

Usage Scenario

The IPv6 DNS client must work with the DNS server to implement dynamic domain name resolution. You can run the dns server ipv6 command to specify the IPv6 address of the DNS server. The IPv6 DNS client sends requests to the specified DNS server for domain name resolution.

Precautions

The IPv6 address of the DNS server must be a global unicast address or link-local address.
- If a link-local address is configured as the IPv6 address of the DNS server, specify the outbound interface for communicating with the DNS server.
- If a global unicast address is configured as the IPv6 address of the DNS server, do not specify the outbound interface for communicating with the DNS server.
The device supports a maximum of six IPv6 addresses of the DNS server.

Example

# Configure the IPv6 address of the DNS server to fc00:1::1.

[sysname] dns server ipv6 fc00:1::1
