Function of dynamic DNS

In Microsoft Windows networks, dynamic DNS is an integral part of Active Directory, because domain controllers register their network service types in DNS so that other computers in the Domain (or Forest) can access them.

Increasing efforts to secure Internet communications today involve encryption of all dynamic updates via the public Internet, as these public dynamic DNS services have been abused increasingly to design security breaches. Standards-based methods within the DNSSEC protocol suite, such as TSIG, have been developed to secure DNS updates, but are not widely in use. Microsoft developed alternative technology (GSS-TSIG) based on Kerberos authentication.

Some freeware DNS server software supports a different dynamic update procedure. They have a built-in DHCP server which automatically updates or adds the DNS data internally with entries about addresses dynamically allotted by the DHCP server, without the user needing to configure dynamic updates. One such server is Dual DHCP DNS.
