Bootstrap DNS

For upstream servers of domain names, SmartDNS will use IP address servers for resolution, so BootStrap DNS usually does not need to be configured. However, if special needs arise, BootStrap DNS needs to be specified, which can be configured in the following ways:

1. Method 1: Specify BootStrap DNS for all servers

   Use the -bootstrap-dns parameter to specify a specific server as the BootStrap DNS.

   server 1.2.3.4 -bootstrap-dns
   server dns.server
   

2. Method 2: For specific servers

   Use the nameserver /domain/bootstrap-dns parameter to specify that a specific domain name uses a specific DNS for resolution.

   # Configure bootstrap DNS
   server 1.2.3.4 -group bootstrap-dns
   nameserver /dns.server/bootstrap-dns
   # This server will use 1.2.3.4 for resolution
   server dns.server
