What does DNS stand for and what does it do?
Like when you are on your iPhone and you go to connect to a wireless connection. And it says DNS right under router.
Quote from site…
"The acronym DNS stands for Domain Name System. A domain is a unique address on the Web that identifies one particular Web site. The Domain Name System is the unique set of domain name records; it transcribes the textual domain names (such as www.google.com) into their numeric equivalents, i.e., IP addresses, in order to make it easier for computer networks to find them via numerical computer languages/protocols."
It can mean Domain Name Service or Domain Name Server. In that context it is asking if you want to enter IP address(es) for DNS servers. That should be automatic if you get an IP address automatically from the network (DHCP) which should also automatically assign netmask, gateway, and nameserver(s). If you manually assign a static (fixed) IP address, you also have to manually set those other things.
Since internet connections are actually done by IP address, DNS allows you to use simpler or easier to remember names to access things on the internet by resolving those names to IP addresses in the background.
