IPCP The Internet Protocol Control Protocol (IPCP) is used, in a similar
way to DHCP, to configure a host with an IP address, gateway and
DNS server, when a PPP network connection is being used. With
the extension Robust Header Compression over PPP, the header
can be compressed for faster data transmission. Similarly, in IPv6
networks, the functionality is provided by the Internet Protocol ver-
sion 6 Control Protocol (IPV6CP).
IPSec IPSec (Internet Protocol Security) is a network protocol for encapsu-
lating other protocols so that they can be transported via the Internet
Protocol (IP) in the form of a tunnel (VPN). The protocol number for
IPSec depends on the protocol used. The Authentification Header
(AH) uses protocol number 51, while the Encapsulating Security
Payload (ESP) uses number 50.
IPv6 See IP.
ISDN Integrated Services Digital Network (ISDN) is a data transmission
standard that includes telephony, fax and data transmission. There
are two ISDN connection variants: Basic Rate Interface and Primary
Rate Interface.
ISDN address The ISDN address of an ISDN device comprises an ISDN number
followed by other numbers that relate to the specific terminal.
ISDN login The ISDN login is used to remotely configure the device via SNMP.
To do so, it needs to have a configured ISDN or wireless connec-
tion.
ISDN number The ISDN number is the network address of the ISDN interface.
ISDN router See Router.
ISP Internet Service Providers (ISPs) supply technical services for using
the Internet.
ITU The International Telecommunication Union (ITU) coordinates the
setting up and operating of telecommunications networks and ser-
vices.
Keepalive Keepalive packets are used to check that the communication part-
ner can be contacted.
Keepalive Keepalive is a mechanism for maintaining the network connection
and for checking that the communication partner can be reached.
Specific packets are usually sent to the network for this purpose.
