Anycast address
A special purpose form or of integrated circuit that provides a way to implement specific programming logic directly into chip form thereby providing the fastest possible execution of such programming logic when processing data what makes it possible for high-speed high volume routes to perform complex address algorithms and management functions that can keep up with that of volumes and time sensitive processing needs

Classless inter domain routing cidr
A IP subnetting scheme in which all subnets use the same size subnet mask which therefore divides the subnetted address space into a fixed number of equal size subnets
Constant link subnet masking clsm

Domain

Domain name
Dtcp IP application layer protocol and service that manages an internet-wide distributed database of symbolic domain names in numeric IP addresses so that the users can be and get resources by name and get the correct IP addresses
Domain name system DNS
The name for the format used to denote numeric IP addresses we’re in four numbers are separated by periods
Dotted decimal notation
A networks connection in which the original sending and receiving IP addresses may not be altered and where I communications connection extends all the way from center to receiver while that connection remains active
End to end connection
An IEEE transformation permitting the burned in Mac addresses of an ICS to be padded in particular ways to create globally unique 64-bit interface identifiers for each interface
Eui-64-format
The portion of an IP address that represents the sum of the network portion of the address plus the number of bits used for submitting at Network address a class b address with a three bit summoning scheme would have an extended Network prefix of night/19 to 16 bits for the default Network portion plus three bits for the seven inning portion of that address with the corresponding subnet mask of 255.255.224.0.
Extended Network prefix
A network boundary device that sits between the public and private sides of a network and provides a variety of screening and inspection services to ensure that only safe authorized traffic flows from outside to inside considered a special type of Bastian host that prevents unauthorized external access to internal networks and manages internal access to external networks
Firewall
The right most bits in an IP address allocated to identify host on a super Network or sub Network
Host portion
An IPv6 addressing unicast and anycast addresses have the lower order bits of their addresses reserved for a bit string that uniquely identifies a particular interface either globally or at a minimum locally
Interface identifier
Computers or other networked devices that really Network traffic from its origin to the destination post
Intermediate hosts
The arm of the isoc originally responsible for registering deep in an allocating public IP addresses it’s now the responsibility of I can n
Internet assigning numbers authority i a n a
An organization that as a primary line of business provides internet access to individuals or organizations
Internet service provider
TCP IP terminology for router that provides access to resources outside the local subnet Network address
IP gateway
The process of replacing one set of numeric IP addresses with another set of numeric IP addresses either because of a change in ISP or an address reassignment
IP renumbering
You type of networking device that can bring switch router and network management functions within a single box makes it possible to create and manage multiples virtual subnets in a single device while offering extremely high bandwidth to individual connections between pairs of devices attached to that device
Layer 3 switch
An addressing scheme that is designed to be used only on a single segment of a local network
Link local address
An address that points directly back to the sender
Loop back address
A sublayer of the data link layer this layer is part of the media Access control definition in which network access methods such as ethernet and token ring apply
Mediae access control layer Mac
One of a block of addresses reserved for use in sending the same message to multiple interfaces or notes members of a community of interest subscribe to a multicast address in order to receive router updates streaming data and so on
Multicast address
That portion of an IP address that consists of the network prefix for the address
Network address
The leftmost octet or bits in a numeric IP address which identifies the network and subnet portions of that address
Network portion
The portion of an IP address that corresponds to the network portion of the address
Network prefix
A type of high air hierarchical address she used to implement open systems interconnection Network layer addressing and a logical point between the network and transport layer in the OSI model
Network service access point nsap
And IP address expressed in dotted decimals or binary notation

Public IP address
A specific level of service guarantee associated with application layer protocols in which time sensitivity requirements for data require that delays be controlled with indefinite guidelines to deliver viewable or audible data streams

Reverse proxying
A form of IP address analysis that permits routers to indicate general interest in a particular Network prefix that represents the common portion of a series of IP network addresses as a way of reducing the number of individual routing table entries that routers must manage

Site local address
A special bit pattern that masks off the network portion of an IP address with all ones
Subnet mask
A form of specialized IP network addresses that identifies the common portion of a series of IP network addresses used when route aggregation is in effect this approach speeds routing behavior and decreases the number of entries necessary for routing tables
Subnetting
A form of specialized IP network address that identifies the common portion of a series of IP network addresses used when route aggregation is in effect
