Domain Name Server A Domain Name Server (DNS) is the Internet’s way to map any valid and registered unique domain name to its actual Internet Protocol (IP) address:

cnn.com becomes 64.236.16.52IP addresses from those four octets, define the actual locations of places on the internetInternet Corporation For Assigned Names and Numbers (ICANN) maintains registrations

Twin Oaks Internet Presence We own a location on the Internet identified by our second-level Domain Name

twinoakstoastmasters.orgWe refer to our domain name for simplicity’s sake instead of its Internet Protocol (IP) address of 66.235.221.12The first part of a second-level domain, such as “www” indicates the type of host (server) within a domain

File Server A File Server is a specialized computer program that allows authorized users to place, use, and retrieve files within their dedicated folder located on the file server

We rent storage space on a file server for the club’s usage, such as:

Images

Web pages

PDF’s

Email/List Server For club-wide email messages, we use an Email/List Server:The email/list server is a specialized computer program that maintains a list of email addresses and associates that list to a particular email addressAny message and its content sent to that particular email address is redistributed to all valid email addresses maintained in that associated listNote: Our list server club-wide email address is not publicized outside of our membership to avoid nuisance messages (spamming) being sent to our members

There could other lists constructed as needed by the clubThe same procedure is used for each list regardless of the number of recipient email addresses
