DNS
Domain Name System
DNS permits the assignment of IP addresses to computers or Domain names, which are easier to remember. A DNS server must administer this information for each LAN with an Internet connection. As soon as a page on the Internet is called up, the browser obtains the corresponding IP address from the DNS server so that it can establish the connection.
On the Internet. the assignment of domain names to IP addresses is based on a hierarchical system. A local PC only knows the address of the local name server. This in turn knows all the addresses of the PCs in the local network and the next higher name servers, which again know addresses and the next higher name servers.
