DNS

Domain Name System. An Internet service that translates domain names into IP

addresses. Domain names are a clear way of representing an Internet address.

The Internet, however, is actually based on IP addresses. For example, the URL

http //www.website.com might actually point to the IP address http

//123.456.789.0. Because maintaining a central list of domain name/IP address

correspondences would be impractical, the lists of domain names and IP

addresses are distributed throughout servers on the Internet in the Domain Name

System. If one DNS server cannot translate a particular domain name, it contacts

another one, and so on, until the correct IP address is returned.

DTIM

Deliver Traffic Indication Message. Used by access points to tell power-save

client devices that a packet is waiting for them.

DSCP

Differentiated Services Code Point is a model in which traffic is treated by

intermediate systems with relative priorities based on the type of services.

EAP-MD5 server

Servers running extensible authentication protocol to provide dynamic,

session-specific wireless encryption keys, central user administration. and

authentication between clients and access points. EAP-MD5 uses MD5 hashing

on client and challenge passwords. The WLSE monitors EAP-MD5 servers.
