DNSUPDAT, which is the proper name of the facility, allows you to make updates to zone data in the primary, without taking the server down, and without an outage while the server reloads its file. This can be used to make long TTL modifications to zone files, permanent changes to machine configurations within the zone. It is, however, most useful for dialup devices which need short TTL entries during the period of time which they are transiently connected. This is particularly useful for permitting a single relay policy for email (most dialup machines are blocked from direct mail into hosts controlled by sane administrators), and is also useful for "tickled" devices. A "tickled" device is one you call, it sees the ringing, and it calls in to establish a connection. It then makes a DNS entry with its dynamically assigned IP address, which permits you to dial in to get IP connectivity on a local number, and remotely access the dialup machine by name; without this, there's no way to know the IP address of the dynamic assignment. This facility is also useful for assigning DHCP lease names, and names based on RADIUS accounting records. I personally don't use this, since I think that machines should do their own stateless autoconfiguration, and DCHP should die. I don't use the RADIUS accounting records because I don't control a RADIUS server these days. > > DNSSEC? > > http://cr.yp.to/djbdns/forgery.html This is substantially incorrect. His reading is based on trusting an exterior zone on the basis of trusting a signature authority; if, on thge other hand, you want to establish your own security associations internally, perhaps going so far as to establish exterior associations with other companies for whom you have a record of their public keys, you can do so. Also, it is out of date: NSI has stated an intent to start signing, as soon as the RFC goes standard. Meanwhile, there's still the license.
