A logical process of combining bits. In ANDing, a bit with a value of 1 plus another bit with a value of 1 results in a 1. A bit with a value of 0 plus any other bit results in a 0.

1)      ANDing –

An IP addressing and subnetting method in which network and host information is manipulated without adhering to the limitations imposed by traditional network class distinctions. CIDR is also known as classless routing or supernetting. Older routing protocols, such as RIP, are not capable of interpreting CIDR addressing schemes.

2)      CIDR –(Classless Interdomain Routing) -

In CIDR notation, the number of bits used for an extended network prefix. For example, the CIDR block for 199.34.89.0/22 is /22.

3)      CIDR block –

In CIDR, a method of denoting network IDs and their subnet boundaries. Slash notation takes the form of the network ID followed by a slash (/), followed by the number of bits that are used for the extended network prefix.

4)      CIDR notation –

An IP addressing convention that adheres to network class distinctions, in which the first 8 bits of a Class A address, the first 16 bits of a Class B address, and the first 24 bits of a Class C address are used for network information.

5)      classful addressing –

A gateway that operates on the Internet backbone.

6)      core gateway –

The gateway that first interprets a device's outbound requests, and then interprets its inbound requests to and from other subnets. In a Postal Service analogy, the default gateway is similar to a local post office.

7)      default gateway –

A TCP/IP utility that queries the DNS database and provides information about a host given its IP address or vice versa. Dig is similar to the nslookup utility, but provides more information, even in its simplest form, than nslookup can.

8)      dig (domain information groper) –

A type of address translation in which a limited pool of Internet-valid IP addresses is shared by multiple private network hosts.

9)      DNAT (Dynamic Network Address Translation) –

The combination of an IP address's network ID and subnet information. By interpreting the address's extended network prefix, a device can determine the subnet to which an address belongs.

10)extended network prefix –

A TCP/IP utility that at its simplest returns either the IP address of a host if its host name is specified or its host name if its IP address is specified.

11)host –

A TCP/IP utility used to show or modify a client's host name.

12)hostname –

A service provided with Windows operating systems that allows one computer, the ICS host, to share its Internet connection with other computers on the same network.

13)ICS (Internet Connection Sharing) –

On a network using the Microsoft Internet Connection Sharing service, the computer whose Internet connection other computers share. The ICS host must contain two network interfaces: one that connects to the Internet and one that connects to the LAN.

14)ICS host –

A mail retrieval protocol that improves on the shortcomings of POP. The single biggest advantage IMAP4 has relative to POP is that it allows users to store messages on the mail server, rather than always having to download them to the local machine. The most current version of IMAP is version 4 (IMAP4).

15)IMAP (Internet Message Access Protocol) –

The most commonly used form of the Internet Message Access Protocol (IMAP).

16)IMAP4 (Internet Message Access Protocol, version 4) –

A standard for encoding and interpreting binary files, images, video, and non-ASCII character sets within an e-mail message.

17)MIME (Multipurpose Internet Mail Extensions) –

A route discovery and analysis utility that comes with UNIX and Linux operating systems. Mtr combines the functions of the ping and traceroute commands and delivers an easily readable chart as its output.

18)mtr (my traceroute) –

A technique in which IP addresses used on a private network are assigned a public IP address by a gateway when accessing a public network.

19)NAT (Network Address Translation) –

A TCP/IP troubleshooting utility that provides information about NetBIOS names and their addresses. If you know the NetBIOS name of a workstation, you can use nbtstat to determine its IP address.

20)nbtstat –

A protocol that runs in the Session and Transport layers of the OSI model and associates NetBIOS names with workstations. NetBIOS alone is not routable because it does not contain Network layer information. However, when encapsulated in another protocol such as TCP/IP, it can be routed.

21)NetBIOS –

A TCP/IP troubleshooting utility that displays statistics and the state of current TCP/IP connections. It also displays ports, which can signal whether services are using the correct ports.

22)netstat –

A TCP/IP utility that allows you to look up the DNS host name of a network node by specifying its IP address, or vice versa. This ability is useful for verifying that a host is configured correctly and for troubleshooting DNS resolution problems.

23)nslookup –

A TCP/IP utility that allows you to look up the DNS host name of a network node by specifying its IP address, or vice versa. This ability is useful for verifying that a host is configured correctly and for troubleshooting DNS resolution problems.

24)nslookup –

A command-line utility that combines the functionality of the tracert and ping commands (similar to UNIX's mtr command) and comes with Windows operating systems.

25)pathping –

An Application layer protocol used to retrieve messages from a mail server. When a client retrieves mail via POP, messages previously stored on the mail server are downloaded to the client's workstation, and then deleted from the mail server.

26)POP (Post Office Protocol) –

The most commonly used form of the Post Office Protocol.

27)POP3 (Post Office Protocol, version 3) –

A network whose access is restricted to only clients or machines with proper credentials.

28)private network –

A network that any user can access with no restrictions. The most familiar example of a public network is the Internet.

29)public network –

A utility for viewing or modifying a host's routing table.

30)route –

The prefix in an IPv6 address that identifies a route. Because route prefixes vary in length, slash notation is used to define them. For example, the route prefix indicated by 2608:FE10::/32 includes all subnets whose prefixes begin with 2608:FE10 and, consequently, all interfaces whose IP addresses begin with 2608:FE10.

31)route prefix –

The Application layer TCP/IP subprotocol responsible for moving messages from one e-mail server to another.

32)SMTP (Simple Mail Transfer Protocol) –

A type of address translation in which each private IP address is correlated with its own Internet-recognized IP address.

33)SNAT (Static Network Address Translation) –

The 64-bit prefix in an IPv6 address that identifies a subnet. A single IPv6 subnet is capable of supplying 18,446,744,073,709,551,616 IPv6 addresses.

34)subnet prefix –

In IPv4, a type of subnet that is created by moving the subnet boundary to the left and using bits that normally would be reserved for network class information.

35)supernet –

A 32-bit number that, when combined with a device's IPv4 address, indicates the kind of supernet to which the device belongs.

36)supernet mask –

A version of the traceroute utility found on some Linux distributions.

37)tracepath –

A TCP/IP troubleshooting utility that uses ICMP to trace the path from one networked node to another, identifying all intermediate hops between the two nodes. Traceroute is useful for determining router or subnet connectivity problems. On Windows-based systems, the utility is known as tracert.

38)traceroute (tracert) –
