My WebServer DNS root zone file is outdated and it has no information about IPv6 and recently changed root server IP address. How do I update my root hints data file under CentOS 7 Server? Under Red Hat / CentOS / Fedora Linux, default location is /var/named/named.root, enter: # wget --user=ftp --password=ftp ftp://ftp.rs.internic.net/domain/db.cache -O /var/named/named.root Reload rndc to update information, enter: # rndc reload Another option is run dig command to fetch information: # dig +bufsize=1200 +norec NS . @a.root-servers.net > /var/named/named.root The root zone's nameservers change over time, don't assume this list is current.
