IP addressing
Every computer on a network needs an IP address
Computers on a LAN have a local IP address -These are dynamic and can only be used on that network
The router has an external IP address. This is static for communicating the internet
Domain names are used so that people don't have to remember the four numbers for every website
The domain name system matches domain names with actual IP addresses
The system is made up of networked DNS severs throughout the world
A name server looks up a domain name in its database and returns the IP address
If the IP address is not in its database, it asks other name servers until it finds the address
