Cricket Liu is the co-author of all of O'Reilly's Nutshell Handbooks on the Domain Name System, "DNS and BIND," "DNS on Windows NT," "DNS on Windows 2000," "DNS on Windows Server 2003," and the "DNS & BIND Cookbook," and was the principal author of Managing Internet Information Services.

Dynamic update is, of course, another way to update zone data without restarting the name server; see "See Dynamically Updating a Zone" in Chapter 7 for details.

As documented at these zones: "." (the root), ARPA, IN-ADDR. Ask // your network administrator for the IP address of the responsible // master name server. It is always good idea to read CERT's security advisories and to subscribe to the Free BSD security notifications mailing list to stay up to date with the current Internet and Free BSD security issues.

options ; // If you enable a local name server, do not forget to enter 127.0.0.1 // first in your /etc/so this server will be queried. Name servers that are serving a lot of clients will benefit more from this approach than individual hosts. To use this mechanism, uncomment the entries below, and comment the hint zone above. NET are available for AXFR from these servers on IPv4 and IPv6: dns.icann.org, dns.*/ /* zone "." ; zone "arpa" ; */ /* Serving the following zones locally will prevent any queries for these zones leaving your network and going to the root name servers.

It can be convenient to become // a slave at least for the zone your own domain is in. // // Before starting to set up a master zone, make sure you fully // understand how DNS and BIND work.

They might have changed since these instructions were last updated. The first key in the listing, with the value 257 after the DNSKEY record type, is the one needed.

With older versions of BIND, just use , as appropriate.

Reloading individual zones, as shown above, was introduced in BIND 8.2.1 and again in 9.1.0.
