Address resource record
type of DNS data record, maps IP add. of internet-conn. device to its domain name
-
APIPA
(automatic private IP add.) automaticly assigns Node's NIC an IP add. from 169.254.0.0 to 169.254.255.255 if an IP add. hasn't been assigned to the interface
-
ARP
(add. resolution protocol) Core protocol in TCP/IP, Network layer, ARP obtains MAC add. of host or node, database mapping MAC add. to host IP add.
-
BOOTP
(Bootstrap Protocol) App. layer protocol in TCP/IP, Centtral list of IP add. and their ass. MAC add. Precursor to DHCP
-
DDNS
(Dynamic DNS) Notifiys Service provider when users IP add. changes, provider propagates DNS record change across the internet
-
DHCP
(Dynamic Host Configuration Protocol) App. layer protocol in HTP/IP, manages the dynamic dist. of IP addresses on a network.
-
DNS
(Domain Name System or Service) Hierarchical way of tracking domain names and their add., mid-1980s, distributed over several key computers accros the internet, DNS is a TCP/IP service , App. layer of OSI

-
ICMP
(internet control message protocol) Core protocol in TCP/IP, notifies sender somthing has gone wroung and packes were not delivered
-
IGMP
(internet group managment protocol or Multicast protocol) TCP/Ip prot., manages multicast trans. , routers use to determine whicg nodes belong to a multicast group
-
internetwork
traverse more than one LAN segment and more than one type of network though a router
-
IP datagram
IP portyion of TCP/IP frame that acts as an envelope for data, holdering info. neccessary for routers to transfer data between subnets
-
IPv4LL
(IP version 4 link local) automatic add. assignment amoung locally connected Nodes, part of Zeroconf
-
Label
char. string that rep. a domain, either top-level, second-level, or third-level
-
Namespace
database of Internet IP add. and their assocuated names distributed over DNS name servers worldwide
-
Network ID
portion of an IP common to all nodes on the same network or subnet
-
NTP
(Network Time Protocol) Syn. clocks of computers on a network, NTP depends on UDP for trans. layer service
-
RARP
(reverse add. resolution protocol) core protocol in HTP/IP, Network layer, RARP table associates IP add. with a node's MAC add., RARP can be used to supply IP addresses to diskless workstations
-
Resolver
any host on the internet that needs to look up domain name information
-
Resource Record
element of a DNS database stored on a name server that contains info. about TCP/IP host names and their addresses
-
root server
DNS server maintained by ICANN and IANA that is an authority on how to contact the top-level domains, such as .com, .edu, .net, .us, ICANN oversees 13 root servers around the world
-
socket
logical add. assigned to a specific process running on a computer, some sockes are reserved for operating system functions

-
TCP/IP core protocols
IP, TCP, and UDP
-
Telnet
terminal emulation protocol used to log on mote hosts using TCP/IP protocol, Telnet resides in the app. layer
-
TFTP
(trivial file transfer protocol) unlike FTP, TFTP uses UDP and does not require you to log on to the host
-
TLD
(top-level domain) the highest level catagory used to distinguish domains. example .org, .com and .net
-
UDP
(user datagram protocol) core protocol for TCP/IP, transport layer, connectionless transport service
-
Zeroconf
(zero configuration) collection of prorocols desighned to simplify setup of nodes on a TCP/IP network, assighns a node an IP add, resolves node's host name and IP add. without requiring a DNS server, descovers service such as print services, without requiring a DNS server
