Usage Guidelines

Usage Scenario

The dns-server command is used on DHCPv6 servers. Before a host accesses the Internet, a DNS server needs to resolve the accessed domain name to an IP address. The DHCPv6 server needs to specify the IPv6 address of the DNS server for the global address pool so that the DHCPv6 client can be connected to the Internet. The DHCPv6 server specifies the IPv6 address of the DNS server when allocating IPv6 addresses to the clients.

Precautions

To specify multiple DNS servers, run the dns-server command to configure multiple DNS server addresses.
A maximum of two DNS server addresses can be configured for each IPv6 address pool. The first assigned DNS server address is used as a primary address. The priority of the first configured DNS server is higher than that of the other DNS server.

Example

# Specify a DNS server with the IPv6 address fc00:1::1 for domain name resolution when IP addresses in the address pool global1 are assigned to clients.
