A DNS address is the address to a server that converts a URL to an IP address. Most DNS address' are provided by your ISP, although there are many free DNS servers available.
The DNS server address refers to the reserved addresses that are used in each of the local network. The router on that network usually connects the users to the internet.

DNS is the domain name system for short .DNS is a system that maps a name to an address . Ip address for Gmail.com is 173.194.36.86 .
There is no such thing as "DNS for youtube". DNS simply is a system that tells you what IP address corresponds to a certain domain name.

TCP/ IP protocol suite uses a DNS client. DNS stands for Domain name system .A DNS server maps a name to an address.
The DNS server is used to translate an alphanumeric address into an IP address that a computer can understand. As such, the computer will know which domain name to contact.
A DNS server converts a name of a web address to a number so that the computer can recognise what website you are looking for through its' IP address.
A DNS Lookup is when a device that supports IP asks a DNS server for the IP address associated with a domain name. The DNS Server must "look up" the IP associated with that domain name.For example, if you were to go to Answers.com in your browser, your computer would initiate a DNS Lookup. This process involves asking the Primary DNS Server for Answers.com's IP address. The DNS Server will ask other servers until the IP address is found and the information returned to you.Assuming it is not cached, to find the IP address for wiki.answers.com, your DNS Server would first ask a DNS Root server for the DNS Server that handles "com". The root server would reply with the IP address for "com". Your DNS Server would then find the DNS Server that handles "com" and ask it for "answers.com". The "com" DNS Server would reply with the IP address for "answers.com". Your DNS server would finally find the DNS Server that handles "answers.com" and ask it for "wiki.answers.com".Once your computer receives the reply containing the IP address for wiki.answers.com, it can finally ask wiki.answers.com for the webpage it hosts.A common analogy is that DNS is like a very large phonebook. You look through the phonebook for the name you want and it will tell you the number you need to dial the person you're looking for. The process of looking up the number is a "DNS Lookup".If you would like to experiment with DNS Lookups, you can use the command line utility "nslookup" in Windows or Linux.
One can increase the speed of internet browsing by changing their DNS server address. A list of DNS servers can be found on the Comcast website. Changing the DNS address to a more reliable one should increase the browsing speed of the computer.
