(dī-nam´ik nat) (n.) A type of NAT in which a private IP address is mapped to a public IP address drawing from a pool of registered (public) IP addresses. Typically, the NAT router in a network will keep a table of registered IP addresses, and when a private IP address requests access to the Internet, the router chooses an IP address from the table that is not at the time being used by another private IP address. Dynamic NAT helps to secure a network as it masks the internal configuration of a private network and makes it difficult for someone outside the network to monitor individual usage patterns. Another advantage of dynamic NAT is that it allows a private network to use private IP addresses that are invalid on the Internet but useful as internal addresses.
Compare with static NAT.
- Dynamic RAM
A type of physical memory used in most personal computers. The term dynamic indicates that the memory must be constantly refreshed (reenergized) or it will lose its contents. RAM (random-access memory) is sometimes referred to as DRAM (pronounced dee-ram) to distinguish it from static RAM (SRAM). Static RAM is faster and less volatile than dynamic […]
- dynamic URL
A URL that results from the search of a database-driven Web site or the URL of a Web site that runs a script. In contrast to static URLs, in which the contents of the Web page do not change unless the changes are coded into the HTML, dynamic URLs are generated from specific queries to […]
- dynamic acceleration
A feature supported by some mice drivers that causes the mouse resolution to depend on how fast the mouse is moved. When you move the mouse fast, the cursor moves proportionally further (the resolution is low). This is useful for jumping across the screen. Without this feature, you might need to sweep the mouse several […]
- dynamic aspect-oriented programming
Dynamic aspect-oriented programming, or dynamic AOP, using wrapper technologies, offers a way of allowing components to be individually customized and extended. Dynamic aspect-oriented programming is relatively straightforward in a trusted environment, where (with the exception of bugs) aspects can be assumed to be safe. In an untrusted public computing environment, new aspects cannot be assumed […]
- dynamic content
Web site or blog content that changes frequently and engages the reader, dynamic content can include animations, video or audio.
