Automatic Private IP Addressing
APIPA
a service in Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008 that can automatically configure client IP addresses in the absence of a DHCP server; APIPA addresses do not contain a default gateway and can only be used to communicate on the local subnet
CIDR notation
the most common means of expressing a CIDR network address , such as 192.168.1.0/24 or 192.168.1.128/25
classful addressing
a means of segregating TCP/IP networks into Class A, Class B and Class C networks based on the network address taking up the 1st, 1st and 2nd, or 1st three octets of the IP address
default gateway
allows a host to communicate with devices that reside on a remote network
host
a computer, printer, or other physical device configured with a network interface card
host address
The portion of an IP address that is unique to an individual device
HOSTS file
text files used to provide name resolution for early TCP/IP networks
IP Address
a means of identifying a unique host on a TCP/IP network
IP Version 4
IPv4
the version of TCP/IP that has been most widely implemented on modern networks
IP Version 6
IPv6
a newer implementation of TCP/IP that includes a much larger address space and numberous security improvements over IPv4
name resolution
the process of mapping an IP address to a human-readable "friendly" name, such as www.lucernepublishing.com
Classless Inter-Domain Routing
CIDR
a means of more granularly segregating TCP/IPP networks based on the number of bytes used by the network address versus the host address
Dynamic Host Configuration Protocol
DHCP
a service used to automate the distribution of TCP/IP addresses and associated configuration information, such as the subnet mask, default gateway and preferred DNS server
fully qualified domain name
FQDN
a DNS name comprised of the host name with the domain name appended to it, such as server1.contoso.com, where server1 is the host name and contoso.com is the domain name
Internet Service Providers
ISPs
commercial or not-for-profit entities that provide customers with a means of accessing the Internet
network address
the portion of an IP address that is shared by all hosts on the same subnet
network address translation
NAT
allows one or more private IP addresses to be mapped to one or more public IP addresses to allow hosts with private IP addresses to communicate on the Internet or another public network
network protocols
provide teh logical "language" to allow computers to communicate acreoss a physical network medium
octets
a portion of an IP address that is 4 bytes in length
routing
the process of transferring data across a network from one LAN to another
static IP address
an IP address that has been manually configured by an administrator
subnet mask
used to define which portion of an IP address is the network address and which portion is the host address
subnet
a logical grouping of computers within a TCP/IP network, used to reduce network traffic and streamline administration
subnetting
The process of subdividing TCP/IP networks into smaller units called "subnets"
Transmission Control Protocol / Internet Protocol
TCP/IP
the most common network protocol in use today; the network potocol used on the Internet
name resolution
the process of mapping an IP address to a human-readable "friendly" name, such as www.lucernepublishing.com
IP Version 6 (IPv6

Network Access Protecton
NAP
Network Access Protection (NAP) is a feature in Windows Server 2008 that controls access to network resources based on a client computer’s identity and compliance with corporate governance policy. NAP allows network administrators to define granular levels of network access based on who a client is, the groups to which the client belongs, and the degree to which that client is compliant with corporate governance policy. If a client is not compliant, NAP provides a mechanism to automatically bring the client back into compliance and then dynamically increase its level of network access
Routing & Remote Access service
