1.	An ADSL (Asymmetric Digital Subscriber Line) router connects a PC to the internet. The DNS server IP address is specified on the ADSL router. Is it necessary to configure the DNS server IP address on the computer to access the internet?
Answer» It is necessary to CONFIGURE the DNS server IP address on the machine. Take the case of a person who wants to VISIT a website. When a user starts a browser and types the website's URL name, a DNS resolution is required, in which the URL name is submitted to a DNS server. The PC must START the DNS REQUEST, which necessitates the configuration of the DNS server IP address on the PC. The DNS request will fail if the PC does not recognise the DNS server IP address, and internet ACCESS will be lost.
