the Internet or an intranet on the TCP/IP network.
HTTP
HTTP (HyperText Transfer Protocol) is the underlying protocol used by the
World Wide Web. It defines how messages are formatted and transmitted,
and what actions web servers and browsers should take in response to vari-
ous commands. For example, when you enter a URL in your browser, this
actually sends an HTTP command to the Web server directing it to fetch and
transmit the requested web page.
IEEE802.1x
This protocol for determining the user authentication method within the LAN
is compatible with wireless and wired LANs. Using the RADIUS server for
user authentication, communication with authenticated users is permitted
while all communication from unauthenticated clients is blocked, excluding
authentication requests.
IPP
IPP (Internet Printing Protocol) is a protocol for end users’ most common
printing situations over the Internet. It allows users to find out about a printer’s
capabilities, submit print jobs to a printer, determine the status of the printer
or print job, and cancel a previously submitted print job.
For more information on using IPP, See “Printing via IPP (Internet Printing
Protocol)” on page 145.
IPsec
The security technology that is used with TCP/IP. A service with enhanced
security can be provided by specifying the encryption of transmission packets
and the authentication protocol.
IPv6
Abbreviation for Internet Protocol version 6.
A protocol that has been prepared to replace the currently used IPv4 protocol
in response to increase in the number of devices that use the Internet.
Additional improvements include 128-bit IP addresses and added security
features.
