Domain Name Service (DNS)
A standard methodology for converting alphanumeric Internet domain names to IP
addresses.
Dynamic Host Configuration Protocol (DHCP)
A communications protocol enabling IP address assignments to be managed both
dynamically and centrally. With DHCP enabled on a node (a system, device, network
card, or access point), when it boots or is connected to a network, an address is
automatically assigned. Each assigned address is considered to be "leased" to a specific
node; when the lease expires, a new IP can be requested and/or automatically reassigned.
Without DHCP, IP addresses would need to be entered manually for each and every
device on the network.
dynamic IP address
A TCP/IP network address assigned temporarily (or dynamically) by a central server,
also known as a DHCP server. A node set to accept dynamic IPs is said to be a "DHCP
client."
Extensible Authentication Protocol (EAP)
Standard that specifies the method of communication between an authentication server
and the client, or supplicant, requesting access to the network. EAP supports a variety of
authentication methods.
Extensible Authentication Protocol Over LAN (EAPOL)
Protocol used for 802.1x authentication.
EAP-TLS
EAP using Transport Layer Security. EAP-based authentication method based on X.509
certificates, which provides mutual, secure authentication. Certificates must be
maintained in the authentication server and supplicant.
EAP-PEAP
Protected EAP-based authentication method based on X.509 certificates. Uses a two-
phase approach in which the server is first authenticated to the supplicant. This
establishes a secure channel over which the supplicant can be authenticated to the server.
Extended Service Set (ESS)
A set of multiple connected BSSes. From the perspective of network clients, the ESS
functions as one wireless network; clients are able to roam between the BSSs within the
ESS.
ESSID
Name or identifier of the ESS used in network configuration.
hostname
The unique, fully qualified name assigned to a network computer, providing an
alternative to the IP address as a way to identify the computer for networking purposes.
Hypertext Transfer Protocol (HTTP)
Protocol governing the transfer of data on the World Wide Web between servers and
browser (and browser enabled software applications).
Hypertext Transfer Protocol over SSL (HTTPS)
A variant of HTTP that uses Secure Sockets Layer (SSL) encryption to secure data
transmissions. HTTPS uses port 443, while HTTP uses port 80.
Independent Basic Service Set (IBSS)
A set of clients communicating with each other or with a network via an access point.
