Name Translation is the process of relating a name (like ' to an IP address (like '74.1') so that a website (or other service) on a computer can be accessed using an easily remembered name, rather than the IP address number of the computer.
Name Translation is implemented via a distributed database known as the Domain Name System.
Most home users who use DSL/Cable routers as DHCP/NAT servers to facilitate multiple host connections to the Internet should turn off dynamic DNS updates.
``So what if my host leaks a few packets to the global Internet? '' The reason is that inconsistent configuration between your home hosts and your local DNS servers can, and often does, cause leakage of DNS updates for private IP addresses to the global Internet.
Leakage of private DNS updates is caused by inconsistent configuration between DNS servers and DHCP client/server entities.
