Dynamic DNS is a type of server that allows any information date that is save in a name server to be updated immediately. This particular DNS service is usually used on computers with varying IP addresses. It is possible to use the Dynamic DNS system for establishing connections with other sites on the Internet without knowing the IP address of a specific computer with the use of this system as well. This system is usually used by people who are connected to one of many different Internet Service Providers (ISPs).

One of the types of programs used to verify this information is TSIG (Transaction Signature), along with a hash system such as a HMAC-MD5 Hash Key. An alternative system has been developed my Microsoft in order to ensure DNS safety by way of the Dynamic DNS protocol. Microsoft’s GSS-TSIG uses Kerberos, which eliminates the need for the installation of a hash key.

Unfortunately Dynamic DNS does not work well with earlier versions of BIND (a very important protective program that some site owners and web hosting providers use for protection against DNS attack). However, later versions of BIND are compatible with quite a number of Dynamic DNS servers. There are both paid and free Dynamic DNS services that exist. There are also firewall services that may be compatible with the Dynamic DNS service. More and more updates are made every single day regarding the use of this type of DNS service.
