It also does what's calling "priming queries", which is to contact one of the known root servers from the hints list, and retrieve and up-to-date authoritative NS set for the root zone from the root zone itself. ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

How does Bind update the root servers? Does it go out and check, or is a

Root hints have been built in forever. (and that's "forever" in
Internet years)

Can bind works without defining root servers
Hi,
I can observe, bind can resolve host names without following entry in
named.conf. could anyone help me to understand this default behavior.
zone "." {
type hint;
file "root.servers";
};
