Chapter 10 Advanced Features and Security Building Up a Large Site−wide Cache with Forwarders Certain network connections discourage sending large volumes of traffic off−site, either because the network connection is pay−per−packet or because the network connection is a slow link with a high delay, like a remote office's satellite connection to the company's network.

You see, while you, as a human being, prefer to remember the names of computers, computers like to address each other by number. On an internet, that number is 32 bits long, dns and bind 5th edition pdf free download, or between 0 dns and bind 5th edition pdf free download 4 billion dns and bind 5th edition pdf free download so.
Pick 10 phone numbers out of the phone book at random and then try to remember them. Not easy? Now flip to the front of the phone book and attach random area codes to the phone numbers. This is part of the reason we need the Domain Name System. DNS handles mapping between hostnames, which we humans find convenient, and internet addresses, which computers deal with. In fact, DNS is the standard mechanism on the Internet for advertising and accessing all kinds of information about hosts, not just addresses.
Another important feature of DNS is that it makes host information available all over the Internet. Keeping information about hosts in a formatted file on a single computer only helps users on that computer.
DNS provides a means of retrieving information remotely from anywhere on the network. More than that, DNS lets you distribute the management of host information among many sites and organizations. You simply make sure your section, called a zoneis up to date on your nameservers.
The Domain Name System gives nameservers the intelligence to navigate through the database and find data in any zone. Of course, DNS does have a few problems.
