Dynamic DNS (DDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information. The term is used to describe two different concepts.
TSIG (transaction signature) is a computer-networking protocol defined in RFC 2845. Primarily it enables the Domain Name System (DNS) to authenticate updates to a DNS database.
Using the RFC2136 DDNS update protocol, it is possible to change DNS zones without accessing the zone files. Management tools known to work that way are Admin4 and NicTool via its nsupdate [4] export mechanism.
Servers with this feature typically provide DNSSEC services. In addition, they support the TSIG (Transaction SIGnature) protocol, which allows DNS clients to establish a secure session with the server to publish Dynamic DNS records or to request secure DNS lookups without incurring the cost and complexity of full DNSSEC support.

A basic one is provided free to use as long as the user refreshes their access from time to time, thus keeping it active. Upgrades to the DDNS comes from purchases. Dynamic IP addresses are common on residential cable or DSL broadband accounts, and the typical users of DDNS would be the users of these types of internet connections. The service ...
A wildcard DNS record is a record in a DNS zone that will match requests for non-existent domain names. A wildcard DNS record is specified by using a * as the leftmost label (part) of a domain name, e.g. *.example.com.
Zero-configuration networking (zeroconf) is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite (TCP/IP) when computers or network peripherals are interconnected. It does not require manual operator intervention or special configuration servers.
It is thus necessary to run the DHCP Client service on pre-Vista machines, even if DHCP isn't being used to configure the machine in order to dynamically register a machine's name and address for DNS lookup. The DHCP Client service registers name and address data whenever they are changed (either manually by an administrator or automatically by ...
