Bash Script

Sample Bash script for extracting Domain Registration wiki page Domainreg and create a root zone file. Set the following shell (environment) variables before running the script to produce a customized zone file header for that root zone that match your DNS server:

  • RNS_FQDN - set this to the fully qualified domain name of your root name server. 
    •  export RNS_FQDN=rns.cp.net
  • RNS_IP - set this to the IP address of your root name server.
  • DNS_ADMIN_EMAIL - set this to the email address of your DNS administrator 
    •  export DNS_ADMIN_EMAIL=admin.cp.net
