What is Variable Length Subnet Mask (VLSM)? – Definition

By Dinesh Thakur

The term variable-length subnet mask (VLSM) refers to the fact that a network can configure with different subnet mask. The basic idea behind VLSM is to offer more flexibility by dividing a network into multiple subnets while optimizing the allocation of varying amounts of host space between subnets. Without VLSM, only one subnet mask can apply to an entire network. It would restrict the number of hosts given the number of subnets required. If you select the subnet mask so that it has enough subnets, you might not be able to assign enough host numbers in each subnet. The same is true for hosts; A mask that allows enough hosts may not provide enough subnet space. VLSM provides the ability to assign subnets with varying numbers of hosts, allowing the network administrator to use the address space better.

IPv4 and IPv6 Addressing

By Dinesh Thakur

As the Internet is a network of networks, addressing, is particularly important. This section provides an initial overview of the addressing problems through the first generation IP protocol IPv4 and IPv6 new generation. [Read more…] about IPv4 and IPv6 Addressing

What is Indirect Addressing?

By Dinesh Thakur

In a computer that allows indirect addressing, the assembly language programmer typically indicates an indirect address by adding a character such as * to the absolute or symbolic address, or by enclosing it in parentheses. [Read more…] about What is Indirect Addressing?

What is Application Service Provider (ASP)?

By Dinesh Thakur

Application Service Provider (ASP): A company that rents out the use of software running on its own SERVERS to remote customers, who may use a THIN CLIENT technology such as CITRIX WINFRAME or a PC and a web-based connection to log on to the service: the viability of such services depends upon the availability of a BROADBAND connection from client to server. [Read more…] about What is Application Service Provider (ASP)?

(IP) Internet Protocol – What is Internet Protocol (IP)?

By Dinesh Thakur

The Internet’s basic protocol called IP for Internet Protocol. The objective of starting this protocol is assigned to interconnect networks do not have the same frame-level protocols or package level. The internet acronym comes from inter-networking and corresponds to an interconnection fashion: each independent network must transport in the weft or in the data area of the packet an IP packet, as shown in Figure. [Read more…] about (IP) Internet Protocol – What is Internet Protocol (IP)?

IPv6 – What is IPv6?

By Dinesh Thakur

IPV6 is also known as IPng (Internetworking Protocol, next generation). The numbers of users of the internet are increasing day by day and the services offered to these users are also increasing. A huge number of addresses are needed to accommodate such vast number of hosts. The internet not only transmits textual data. It also allows us to transmit audio and video data. In such data, the high speed data transfer is desired. Internet working protocol version 6 (IPv6) was developed to overcome the shortcomings of IPv4. [Read more…] about IPv6 – What is IPv6?

Classless Addressing – What is Classless Addressing?

By Dinesh Thakur

• The fast growth of Internet led to the near depletion of the available addresses. [Read more…] about Classless Addressing – What is Classless Addressing?

Supernetting – What is Supernetting?

By Dinesh Thakur

• Supernetting is an addressing scheme in which several class C blocks can be combined to create a larger range of addresses. [Read more…] about Supernetting – What is Supernetting?

Subnet Mask – What is Subnet Mask?

By Dinesh Thakur

• Subnet mask uses the same format and representation technique as IP addresses. [Read more…] about Subnet Mask – What is Subnet Mask?

IP Address Classes or Classful addressing

By Dinesh Thakur

• IP addressing supports five different address classes: A, B, C, D and E. Only classes A, Band C are available for commercial use. [Read more…] about IP Address Classes or Classful addressing

What is IP Address? Types of IP Address

By Dinesh Thakur

In order to provide computer to computer communication via Internet, we need a global addressing scheme. Such an addressing is provided by Internet Protocol (IP) at the network layer.
It is a 32-bit address This is called an IP address or logical address. Which is made up of the network ID, plus a unique host ID. This address is typically represented with the decimal value of each octet separated by a period (for example, 192.168.7.27).   Every Host and router on the internet has an IP Address. This IP address is unique and no two devices on the Internet can have the same address at the same time. [Read more…] about What is IP Address? Types of IP Address

SubNetting – What is Subnetting?

By Dinesh Thakur

The process of subnetting involves dividing a network up into smaller networks called subnets or sub networks. Each of these subnets has its own specific address. To create these additional networks we use a subnet mask. The subnet mask simply determines which portion of the IP address belongs to the host. The subnet address is created by dividing the host address into network address and host address. [Read more…] about SubNetting – What is Subnetting?

What is MAC address (Media Access Control)? – Definition

By Dinesh Thakur

In a local area network (LAN) or other network, the MAC (Media Access Control) address is your computer’s unique hardware number. (On an Ethernet LAN, it’s the same as your Ethernet address.) [Read more…] about What is MAC address (Media Access Control)? – Definition

Private IP Address – What is a Private IP Address?

By Dinesh Thakur

An IP address is equivalent to your postal address and just like the mail service, each computer has an address so that it will only receive the information that is send by someone else. [Read more…] about Private IP Address – What is a Private IP Address?

Public IP Address – What Is a Public IP Address?

By Dinesh Thakur

An IP address is considered public if the IP number is valid and falls outside any of the IP address ranges reserved for private uses by Internet standards group. Public IP addresses are used by servers (including those for Web sites and DNS servers), network routers or any computer connected directly to the Internet via a modem. [Read more…] about Public IP Address – What Is a Public IP Address?

Multihomed – What is Multihomed?

By Dinesh Thakur

A Computer with multiple IP addresses to connected networks is known as Multihomed. A multihomed host is physically connected to multiple data links that can be on the same or different networks. For example, a computer with a Windows 2003 Server and multiple IP addresses can be referred to as “multihomed” and may serve as an IP router. [Read more…] about Multihomed – What is Multihomed?

IPV4 vs IPV6

By Dinesh Thakur

Internet protocol Version 4 (IPv4): Internet protocol is glue that holds the internet together. It transfers the datagrams from source to destination without considering that whether the machines are on the same network or not. IP is the main transport mechanism used by TCP/IP suit of protocols. IP provides connection-less, unreliable services. [Read more…] about IPV4 vs IPV6
